Abstract
Influence of layered silicate types on composite ratio of multi-dimensional nanomaterials (MDNs) in styrene-butadiene-styrene copolymers modified asphalt (SBSMA) was investigated. Two types of layered silicate, organic expanded vermiculite (OEVMT) or organic montmorillonite (OMMT), were selected to combine MDNs with nano-titanium (nano-TiO2). Physical, rheological and aging characteristics of SBSMA with MDNs were tested. The results show that introducing MDNs can augment the ductility, viscosity, elasticity and rutting factor of SBSMA to a certain extent, and the OMMT + TiO2 leads to more apparent increase in viscosity compared with the OEVMT + TiO2. Moreover, the physical and rheological properties of SBSMA after thermo-oxidative and ultraviolet aging can be improved simultaneously by introducing MDNs, and the improvement effect depends on the composite types and ratios. The optimal ratios of MDNs in SBSMA, OEVMT(1%) + TiO2(3%) and OMMT(1%) + TiO2(2%), are recommended. Furthermore, the OEVMT(1%) + TiO2(3%) possesses the better resistance for thin film oven test and ultraviolet aging, while the OMMT(1%) + TiO2(2%) has the better resistance for pressure aging vessel aging.
