Microstructural design and thermal characterization of composite diatomite-vermiculite paraffin-based form-stable PCM for cementitious mortars

The thermal performance of cementitious mortars can be improved with the use of form-stable phase change materials (PCMs) consisting of a solid-liquid paraffin mix impregnating diatomite in a diatomite-vermiculite mineral system. The present study includes designing, developing, and characterizing a novel PCM based on a combination of diatomite and calcined, expanded vermiculite, and an optimized paraffin system consisting of a mixture of solid paraffin and naphthenic oil. The diatomite is expected to store the paraffin and wrap the vermiculite particles, increasing the amount of stagnant air. X-ray fluorescence is used to assess the chemical composition of the diatomite and vermiculite. Differential scanning calorimetry (DSC) and Fourier transform infraredspectroscopy (FT-IR) measurements are used to characterize the paraffin mixes aimed at optimum performance for residential and commercial buildings. PCM samples made from paraffin and diatomite (PCM1), vermiculite (PCM2), and a mix of diatomite and vermiculite (PCM(1 + 2)) are characterized by scanning electron microscopy and FT-IR. Cement mortars are prepared in the volume ratios of 1:4 cement:sand (reference mortar), 1:4:1 cement:sand:diatomite, 1:4:1 cement:sand:vermiculite, and 1:4:1 cement:sand:PCM. The thermal properties of these materials are evaluated. The DSC results of the paraffin mixtures indicate that 20% naphthenic oil is the ideal concentration in the paraffin mixture to optimize the solid-liquid temperature (57.45 °C) and latent heat for building applications (159.42 J/g). All PCMs have reduced thermal conductivities compared to the reference mortar (1.47 W/m·K), with the lowest being associated with the PCM(1 + 2) sample (0.82 W/m·K). The PCM(1 + 2) sample also presents an improved combination of diffusivity, volumetric heat capacity, and thermal resistivity. The simultaneous addition of vermiculite and diatomite to the PCM composition improves the thermal properties, while maintaining the basic characteristics such as chemical and structural stability.

Modified Soybean Oil as a Processing Oil for Styrene-Butadiene Rubber Tire Tread Compounds

ABSTRACT Soybean oil (SBO) was modified with polystyrene via a radical graft polymerization reaction for use as a processing oil in tire tread compounds. Poly(styrene-butadiene)/polybutadiene rubber compounds with silica and carbon black, containing different processing oils including naphthenic oil (NO), aromatic oil (AO), SBO, and polystyrene-modified SBO (SBO-PS), were formulated, vulcanized, and tested. The curing behavior, mechanical properties, and dynamic properties were investigated. The cure test results showed that all SBO-based rubbers had a shorter scorch time and cure window than the NO- and AO-based rubbers. The tensile tests demonstrated that partial and complete replacement of NO with SBO led to reduced tensile modulus but increased elongation of rubber. For the rubbers compounded with SBO-PS and with a 50/50 mixture of NO/SBO-PS, tensile strength and elongation were higher than for the NO-based rubber. The same tendency was observed when SBO-PS–based rubbers were compared with SBO- and AO-based rubbers. SBO-PS–based rubbers demonstrated better tensile properties than AO-based rubbers and far better properties than SBO-based rubbers. In the tear resistance test and durometer hardness test, SBO-PS contained rubbers that showed similar properties to NO-containing rubber. The dynamic mechanical analysis of SBO-PS–containing rubbers demonstrated that use of this compound in tire treads is expected to improve both rolling resistance and wet traction when compared with an AO-based rubber. The modification of SBO with grafted PS is a promising method of making processing oil, which can replace petroleum-based processing oils with bio-based renewable oils in tire tread compounds while improving their properties.

A Crude Awakening: Effects of Crude Oil on Lipid Metabolism in Calanoid Copepods Terminating Diapause.

Calanus finmarchicus and Calanus glacialis are keystone zooplankton species in North Atlantic and Arctic marine ecosystems because they form a link in the trophic transfer of nutritious lipids from phytoplankton to predators on higher trophic levels. These calanoid copepods spend several months of the year in deep waters in a dormant state called diapause, after which they emerge in surface waters to feed and reproduce during the spring phytoplankton bloom. Disruption of diapause timing could have dramatic consequences for marine ecosystems. In the present study, Calanus C5 copepodites were collected in a Norwegian fjord during diapause and were subsequently experimentally exposed to the water-soluble fraction of a naphthenic North Sea crude oil during diapause termination. The copepods were sampled repeatedly while progressing toward adulthood and were analyzed for utilization of lipid stores and for differential expression of genes involved in lipid metabolism. Our results indicate that water-soluble fraction exposure led to a temporary pause in lipid catabolism, suggested by (i) slower utilization of lipid stores in water-soluble fraction-exposed C5 copepodites and (ii) more genes in the β-oxidation pathway being downregulated in water-soluble fraction-exposed C5 copepodites than in the control C5 copepodites. Because lipid content and/or composition may be an important trigger for termination of diapause, our results imply that the timing of diapause termination and subsequent migration to the surface may be delayed if copepods are exposed to oil pollution during diapause or diapause termination. This delay could have detrimental effects on ecosystem dynamics.

Effect of different contents of nano-SiO2 particles on water diffusion behavior in insulating oil

As an important component of the internal insulation system in a transformer, insulating oil will gradually age during the long-term operation of the transformer, which will lead to a degradation of its insulation performance. Previous studies have demonstrated that the addition of nano-SiO2 particles can effectively improve the breakdown voltage of insulating oil. Nano-SiO2 can effectively restrain the movement of water molecules in oil, which is one of the important reasons for nano-SiO2 particles to increase the breakdown voltage. The diffusion behaviors associated with different water contents in insulating oils with different nanoparticle contents are discussed herein, and the mechanisms at work in nano-SiO2 modified insulating oils are described on the molecular level. In this paper, simulations were based on naphthenic mineral oil, according to the mass ratio of the alkanes, which can fully represent the main physical and chemical properties of the insulating oil were employed in building the model, the mass-based percentages of water in the models were 1%, 3% and 5%, within each group, the models included an oil/water mixture containing nano-SiO2 which the mass-based percentages of nano were 1%, 2%, 3%, 4%, 5%. Prior to molecular dynamics simulations, the model was geometrically optimized, after which it was annealed and again geometrically optimized. Those systems that achieved equilibrium and energy convergence after this process could be employed for the molecular dynamics simulation. Through the analysis of the experimental results, the optimal concentration of nano-SiO2 particles for moisture binding in insulating oil was studied from a microscopic point of view. These results should assist in providing a theoretical foundation for further research regarding nano-modified insulating oils. In engineering applications, the content of nanometer SiO2 particles can be changed according to the moisture content at different times in the oil, so as to achieve the optimal binding of water, thus keeping the insulating oil with the best electrical performance.

Effect of surface contamination on the durability and strength of stainless steel – polyisobutylene pressure-sensitive adhesive bonds

Cleaning of substrate's surface with a solvent is a standard step in a procedure of adhesive joints preparation while carrying out adhesion tests. However, is cleanliness of substrates really so important? The effect of contamination of substrate's surfaces with vegetable (sunflower) and mineral (naphthenic) oils on the strength and durability of adhesive joints formed by neat and organoclay-filled polyisobutylene-based PSAs with a stainless steel substrate was studied. For the filled composition, the strength of the adhesive joints was higher, even with the contaminated surface, than for the system with the neat PIB. Contamination of the surface leads to the formation of a weak layer of plasticized polymer, which contributes to decreasing of the adhesion strength and durability. These parameters, however, are restored over time, which could be connected with the absorption of the contaminants by the adhesive material, as a result of polymer swelling, and their migration to the bulk of the adhesive. The ability of contaminants that can be absorbed and removed from the surface into the bulk of the adhesive is determined by their solubility in the adhesive. It was demonstrated using laser microinterferometry method that PIB is miscible with naphthenic oil, whereas PIB − sunflower oil system exhibits upper-critical-solution-temperature behavior. These observations provide an explanation to the growth trends of durability and strength of the joints over time in the cases of sunflower and naphthenic oil contamination of the substrate's surface.

Off-line TLC-IR (UATR) characterization of additives in EPDM rubber

Abstract Sulfur donor accelerators and vulcanization agents, such as peroxides, due to their chemical characteristics and good thermal stability properties in rubber formulations, are essential to provide solutions in different sectors, such as aerospace and automotive, since they reduce the polymer degradation process (reversal), which can influence the performance of the elastomeric material. In this way, the use of methodologies for the components knowledge of a formulation is imperative for the structure proper establishment/property relationship of the elastomeric artifacts. The development of methodology that can separate and characterize the rubber formulation components is a constant challenge, still allows gaps, and is usually done by conventional but not coupled instrumental techniques. In this scenario, this paper aimed to contribute to the use of the off-line coupling of thin-layer or thin-layer chromatography (TLC)/infrared spectroscopy (FT-IR), by universal attenuated total reflection (UATR) for N-cyclohexyl-2-benzothiazolesulfenamide (CBS), tetramethyl thiuram disulphide (TMTD) and dicumyl peroxide (DCP), in formulations of ethylene and propylene diene monomer (EPDM) rubber containing the plasticizer naphthenic oil. This plasticizer was characterized in formulations that presented higher content of this compound, but the eluting systems were not effective in separating DCP. However, better separation of CBS and TMTD was observed.

Influence of extender oil composition on flowing property, thermal stability, and morphology of styrene‐b‐ethylene‐co‐butylene‐b‐styrene copolymer/polypropylene/oil blends

In this study, a series of styrene‐b‐ethylene‐co‐butylene‐b‐styrene copolymer (SEBS)/polypropylene (PP)/oil blends with different kinds of oil composition was developed through melt blending. The effect of oil with different composition and properties on its phase equilibrium and “redistribution” in multiphasic SEBS elastomer was systematically studied for the first time. Moreover, an integral influencing mechanism of oil composition on the structure and properties of SEBS/PP/oil blends was also put forward. The mineral oil was mainly distributed in ethylene/butylene (EB)/PP phase, which greatly enhanced the processing flowability of SEBS/PP/oil blends. With increasing oil CN content, a redistribution of oil appeared and excess naphthenic oil (NO) entered the interphase of soft and hard phases. The dynamic mechanical thermal analysis (DMTA) analysis indicated that the polystyrene (PS) phase was plasticized, which also helped to improve the processing fluidity of blends. However, the plasticizing of physical cross‐linking point PS resulted in a decrease in mechanical strength and thermal stability. Small‐angle X‐ray scattering (SAXS) and transmission electron microscope (TEM) results showed that PS phase (45 nm to 55 nm) cylindrically distributed in EB/PP/oil matrix, the excess NO in the interphase enlarged the distance between PS phase and widen the escape channel for oil migration. At over 45% oil CN content, the electron density difference between soft and hard phases reduced to the minimum, same as TgPS, indicating a deeper plasticizing effect. The PS phase swelled and exhibited elastic behavior; thus, the force could be uniformly transferred between two phases. Importantly, a recover in strength and thermal stability was observed in O‐5 blend. This work significantly filled the gap of studies in oil‐extended thermoplastic elastomers (TPEs), exhibiting great theoretical guiding significance and application value.

Effect of Quenching Media and Tempering Temperature on Fatigue Property and Fatigue Life Estimation Based on RBF Neural Network of 0.44 % Carbon Steel

Abstract. In this work, the effect of the quenching media (brine, water, and two types of naphthenic mineral oils) and the tempering temperature (200, 400, 600 ∘C) on the static mechanical properties and the fatigue life has been investigated using 300 fatigue and 36 static tension tests. S–N curves and standard deviations of fatigue life under each heat treatment condition were calculated and shown. The fracture surfaces of the selected 11 specimens were observed by the scanning electron microscope and the reasons of affecting the fatigue life were discussed. To estimate the mean fatigue life under the conditions of any given tempering temperature and cycle stress amplitude based on 300 fatigue tests, the mean fatigue life estimation method based on RBF neural network was presented and verified by 12 other fatigue tests. The test results have shown that (1) the mean fatigue life decreases with the increase of tempering temperature for the same quenching media, (2) the mean fatigue life using brine is more than water which is more than naphthenic mineral oils for the same tempering temperature, and (3) the proposed method based on RBF neural network could accurately estimate the mean fatigue life when the tempering temperature and cyclic stress amplitude are given for each quenching medium.

Effects of the chemical structure of surfactants on the stability of naphthenic oil-based metalworking fluids

In this study, various nonionic surfactants (NS) with different ethylene oxide (EO) numbers and tail lengths and its binary blends with anionic surfactants (AS) were used as emulsifiers for naphthenic oil to form the microemulsion metalworking fluids (MWFs), and the effects of them on the stability of the emulsion system were investigated by formulation triangle method. The results indicated that binary complex surfactants of NS and AS as emulsifiers exhibited better emulsifying effect than that of single NS. NS with different EO numbers and tail lengths presented various emulsifying effects. NS (EO = 10) exhibited the greatest number of stable formulations, especially the TX-10, but no linear relationship existed between the number of stable formulations and the tail length of NS. In addition, aromatic primary alcohol ethoxylate (APAE) series surfactants containing benzene groups similar to the cycloalkanes in the naphthenic oil so that presented the best emulsifying affect and the greatest number of stable formulations. The co-surfactant of sodium dodecyl benzene sulfonate (SDBS) binary blends with NS exerted the best synergistic effect, and the stable formulations numbers were ranged from 5 to 7, next sodium stearate (SS) comes last followed by sodium dodecyl sulfate (SDS-1) and sodium dodecyl sulfonate (SDS-2).

Tribological performance of nanographite-based metalworking fluid and parametric investigation using artificial neural network

This paper investigates the impact of palm oil methyl ester (POME) and graphite nanoflakes as additives on the thermophysical and tribological properties of naphthenic and groundnut oil blends. Different ratios of the two oil blends containing the selected additives were formulated and tested. The results show that both POME and graphite nanoflakes could be potential friction modifiers. Notably, the four-ball tribometer test reveals that the addition of 7 vol% of POME to naphthenic oil and 0.01 wt% graphite nanoflakes to naphthenic oil results in the reduction of wear scar diameter by 24% and 59%, respectively. Surface micrographs of aluminum workpiece subjected to simple turning operation in a CNC machine corroborated the wear test results. POME in naphthenic oil resulted in better surface finish relative to POME-formulated groundnut oil. The experimental data were analyzed using artificial neural network (ANN) to gain a better understanding of the entire work. The sensitivity analysis developed from the chosen ANN models exhibited the nature of influence of the input parameters (groundnut concentrations, POME, and naphthenic oil) on the outputs (Noack volatility, thermal conductivity, and wear).

Bio‐processing aids based on jatropha seed oil and its epoxidized derivatives in carbon black‐reinforced natural rubber

Jatropha seed oil (JSO) is renewable oil with unique characteristics including a high flash point, low viscosity and saponification value, and a solubility parameter close to that of natural rubber. The incorporation of JSO and its epoxidized derivatives containing 50% (EJSO‐50) and 100% mole epoxide groups (EJSO‐100) in carbon black‐filled natural rubber was compared with the incorporation of paraffinic, naphthenic, and treated distillate aromatic extract oils in a range of 2–10 phr. The results showed that JSO promoted good rubber processability similar to that achieved with paraffinic and naphthenic oils, with the advantages of the shortest cure time and scorch time. However, it was found that the epoxide groups especially in EJSO‐100 can interfere in the vulcanization reaction resulting in poorer cure behaviors and mechanical properties. The abrasion resistance of the rubber containing JSO was the highest and progressively improved in a range of 4–8 phr. Moreover, using the various oils at this range of values can improve filler dispersion, sustain the tensile properties, and achieve a balance between wet grip and rolling resistance. J. VINYL ADDIT.

Performance de óleos naftênicos: estabilidade térmica e lubricidade

Os óleos minerais são constituídos de moléculas orgânicas que apresentam um processo de degradação termo-oxidativa complexo. O objetivo deste trabalho foi avaliar a cinética de degradação térmica dos óleos naftênicos NH10, NH20 e NH140, por meio de termogravimetria, e analisar a lubricidade dos óleos NH20 e NH140, por meio de um sistema mecânico com engrenagens (teste de bancada). Os parâmetros energia de ativação e resistência térmica foram determinados com as metodologias descritas nas normas ASTM E1641−16 e ASTM E1877–17. Os resultados indicaram a maior estabilidade térmica para o NH10, o que pode ser confirmado pela resistência térmica (220,93 °C) e pela energia de ativação (92,974 kJ mol-1), cujos valores são superiores aos dos óleos NH20 (187,06 °C, 42,856 kJ mol-1) e NH140 (133,53 °C, 45,282 kJ mol-1). Nos ensaios de lubricidade do NH20 (base para lubrificantes) e NH140 (base para graxas), analisaram-se os parâmetros valor de root mean square (RMS), fator de crista e fator K. Os resultados quanto ao fator K mostram que o valor obtido para o sistema de engrenagens sem lubrificação (187,75) foi maior do que o obtido para o sistema lubrificado com NH20 (185,16) e NH140 (28,88), e esses valores são consistentes com ensaios de desempenho de lubrificantes.

In vitro toxicity testing in hemocytes of the marine mussel Mytilus galloprovincialis (L.) to uncover mechanisms of action of the water accommodated fraction (WAF) of a naphthenic North Sea crude oil without and with dispersant

Dispersants used in oil spills could result toxic to marine organisms and could influence the toxicity of oil compounds. The aim of this work was to uncover the mechanisms of action of the water accommodated fraction (WAF) of a naphthenic North Sea crude oil produced at 10, 15 and 20 °C without and with the dispersant Finasol OSR52 (WAF and WAFD, respectively) using hemocytes of the marine mussel Mytilus galloprovincialis. Primary cultures of hemocytes were exposed in glass-coated microplates to different WAF or WAFD dilutions (0.25, 2.5, 25, 50 and 100%) and to the dispersant alone at the same concentrations present in the WAFD dilutions (1.25, 12.5, 125, 250 and 500 mg/L). Of the two in vitro approaches tested, the second one was selected which involved exposure of hemocytes for 4 h to unfiltered WAF, WAFD and dispersant dilutions without cell culture media. WAF decreased hemocytes viability only at the highest dilution whereas WAFD and the dispersant alone were cytotoxic at the three highest concentrations. Temperature of production of WAF, WAFD and dispersant did not influence their cytotoxicity to hemocytes. WAF increased ROS production and MXR transport activity in hemocytes. Exposure to WAFD and dispersant increased ROS production, provoked plasma membrane and actin cytoskeleton disruption and decreased phagocytic activity. In conclusion, the dispersant tested was toxic to mussel hemocytes and it greatly increased the toxicity of WAFD. The present data could be useful for the environmental risk assessment of oil spills and their remediation strategies in the marine environment.

INVERSE GAS CHROMATOGRAPHY STUDY OF HANSEN SOLUBILITY PARAMETERS OF RUBBER PROCESS OILS (DAE, TDAE, MES, AND NAP)

ABSTRACT Process oils are used for rubbers to improve their flexibility and processability in industry. The solubility parameter is a convenient way to determine the solubility of materials. Inverse gas chromatography was used to calculate the solubility parameters and depict solubility spheres for distillated aromatic extract (DAE), treated distillate aromatic extract (TDAE), mildly extracted solvate (MES), and hydro processed naphthenic oil (NAP). Results showed that despite the similarity in values of the solubility parameters of DAE and TDAE at ambient temperature, increasing temperature led to a significant difference in values. In contrast to other oils, TDAE showed a better compatibility with polar solvents. In addition, the interaction parameters showed no specific dependence on the temperature for DAE, MES, and NAP, except for polar solvents and TDAE. DAE had the highest compatibility with aromatic solvents. Upon raising the temperature to values greater than 100 °C, the compatibility trend between oils and toluene was the same for all oils investigated, except for TDAE, which increased with increasing temperature whereas others showed a reduction. The increase in the alkyl chain was also effective in increasing the compatibility of the probes as well as their interaction parameter values. The solubility parameters (δ2) of process oils were determined to be 18.9, 18.9, 18.5, and 19.0 (J/cm3)0.5 for DAE, TDAE, NAP, and MES at 25 °C, respectively.

Studies of different types of insulating oils and their mixtures as an alternative to mineral oil for cooling power transformers

Because of their availability and low cost, mineral oils have been widely used for a long time in power transformers to allow their insulation and cooling. However, their low fire safety and low biodegradability potential have made it necessary to look for other insulating liquids as an alternative to this mineral oil used in high voltage electrical equipment. This work presents an experimental study to compare between the physicochemical characteristics of mineral oil, olive oil, sunflower oil and different oil mixtures. In order to determine mainly the breakdown voltage and the electrical field intensity of electro-convection, oils insulating should be mixed in precise amounts. All tests have been realized in accordance with the standard test procedures: IEC 60156, IEC 60245 and IEC 61125. The obtained results of testing new as well as aged oil samples concerning the resistivity, the dissipation factor tgδ, the conductivity, the viscosity, the breakdown voltage, the increase of the water content and the flexibility of the oil to the movement in an electrical field, show that a half mixture of naphthenic oil and olive oil could be a potential liquid for the insulation of electrical devices and especially power transformers mounted in areas which have a non-cold climate.

Analysis and mechanism of adsorption of naphthenic mineral oil, water, formic acid, carbon dioxide, and methane on meta-aramid insulation paper

Based on surface science, adsorption of mineral oil, water, gas products (typified by CO2 and CH4), and acids (typified by formic acid) on meta-aramid insulation paper has been investigated by molecular dynamics simulations. When the adsorption process finishes, the free volume fraction in the crystalline region is very small owing to the stable molecular arrangement of fiber. In addition, the number of pores on the surface of the meta-aramid fiber and the pore size are small, and the stable configuration of hydrogen bonds plays an important role, so it is difficult for the mineral oil and aging products to enter the meta-aramid crystalline region. The irregular arrangement of molecules in the amorphous region means that it is easier for the mineral oil and aging products to enter the amorphous region than the crystalline region, and the influence of these substances on the amorphous region is greater than that on the crystalline region. The order of the adsorption strengths of the four types of aging products on meta-aramid fiber is formic acid > water > CO2 > CH4. Therefore, it is necessary to monitor the acid and water contents in transformers with meta-aramid insulation paper as the solid insulation material.

Effect of wood flour and naphthenic oil on morphology, rheological and mechanical properties of EPDM/PP/AL composite

Abstract Thermoplastic elastomer (TPE), made from ethylene propylene diene monomer (EPDM) and polypropylene (PP) base on reactive blending, has an excellent processing performance and characteristics and a wide range of applications. In this paper, EPDM, PP and ammonium lignosulfonate (AL) were selected as raw materials, wood flour (WF) of poplar tree was used as filler, naphthenic oil was used as plasticizer, DCP vulcanization system with dynamic vulcanization was carried, to make a new kind of composite material. This research studied the influences of wood flour and naphthenic oil content on the microstructure, mechanical properties and rheological properties of the composite material. The result showed: the content of wood flour and naphthenic oil has big impact on composite material. With the increase of the wood flour content, the mechanical properties are increased firstly and then decreased. The viscosity and modulus of the composite is improved with the increase of wood flour. With of the increase of the amount of naphthenic oil, the mechanical properties, viscosity and modulus of the composites decreased. When the content of wood flour is between 30–60 parts and the content of naphthenic oil is less than 20, the EPDM/PP/AL composite is suitable for using as the core layer elastic material of composite floor.

Oxidative stability of mineral naphthenic insulating oils: Optimization of commercial antioxidants and metal passivators

Mineral naphthenic oil is normally used in transformers, circuit breakers and other electrical equipment for insulating and cooling functions. Due to their usage conditions, it may be subjected to oxidation reactions caused by the presence of oxygen, water and metals, affecting the oil performance. Using the ASTM D2440 method, oxidation studies were carried out on insulating oil, using commercial antioxidants and metal passivators, to assess and compare their thermal oxidative stability, monitored by FTIR analysis, total acid number and sludge content on the oxidized samples. An experimental sequence for combinations of antioxidants and metal passivators was devised to seek the best concentrations that could be used to improve the stability of the insulating naphthenic oil. The combination of antioxidant Irganox L115 and metal passivator Irgamet 039 achieved the best performance in inhibiting the oil oxidation among the studied samples.

The Effect of Direct-to-Plant Styrene-Butadiene-Styrene Block Copolymer Components on Bitumen Modification.

Five types of material, styrene-butadiene-styrene block copolymer (SBS), ethyl-vinyl-acetate (EVA), naphthenic oil, maleic anhydride grafted ethylene-vinyl acetate copolymer (EVA-g-MAH) and butylated hydroxytoluene (BHT) were used as the raw ingredients for manufacturing direct-to-plant SBS in this paper. Thirteen kinds of direct-to-plant SBS with different EVA/SBS and naphthenic oil/SBS were prepared as well as the processes diagrammatic sketch of dispersion and swelling of direct-to-plant SBS modifier in bitumen were discussed. Microscopic images of direct-to-plant SBS modified bitumen with different components were obtained using fluorescence microscopy. The micro-images were analysed and quantified with MATLAB software. The influence of key components on the micro-morphology of direct-to-plant SBS-modified bitumen is discussed, followed with the tests on melting points and the melting indexes of direct-to-plant SBS with different EVA/SBS and naphthenic oil/SBS. The performances test of bitumen and bituminous mixture modified by these direct-to-plant SBS were also conducted. Results show that, with the ratio improvement of EVA/SBS or naphthenic oil/SBS, the number of the pixel dot number of area (SBS) in microscopic images increased. Enlargement of the pixel dot number of centre line elongate and the structure fineness was observed, indicating that the dispersion and swelling effect of the SBS modifier in bitumen had been improved. Meanwhile, the macro index, such as the melting point and melting index of direct-to-plant SBS, was also improved corresponding to the increase of EVA/SBS ratio or naphthenic oil/SBS ratio. With the addition of EVA or naphthene oil content, penetration and ductility of direct-to-plant SBS modified bitumen received gradual enhancement, but the softening point and viscosity were found out to be decreased. The high-temperature and low-temperature performances of direct-to-plant SBS modified bituminous mixture can be effectively improved by adding EVA or naphthenic oil. By meeting the required performances of direct-to-plant SBS, modified bitumen and bituminous mixture, the component of direct-to-plant SBS is recommended as, SBS:EVA:naphthenic oil:EVA-g-MAH:BHT is 1:0.1–0.5:0.05–0.2:0.03:0.05. For the compatibleness of SBS with different bitumen are different, necessary tests verification is recommended to be carried out prior to usage.
