Abstract

The article presents the results of research on the production of polymer-bitumen binder (PBB) based on mixtures of non-oxidized and oxidized petroleum products, namely high-viscosity tar, darkened vacuum distillate, and oxidized petroleum bitumen 70/100, obtained at technological installations of Limited Liability Partnership (LLP) “JV Caspi Bitum’’ and styrene-butadiene-styrene (SBS) block copolymer brand L 30-01A modifier in the presence of a stabilizer. The results obtained show that the introduction of the SBS modifier in the presence of a sulfur stabilizer improves the performance characteristics of PBB, such as elasticity, ductility, softening temperature, penetration, and brittleness temperature.

Highlights

With insignificant transport loads, conventional building materials can provide an acceptable quality of work for several decades, but recently this situation has changed dramatically
At many modern oil refineries, there is a tendency to increase the depth of selection of distillate fractions from fuel-oil residual during vacuum distillation in order to increase the depth of crude oil refining. This leads to a significant increase in the viscosity of the resulting tar, which according to numerous studies is not the optimal raw material for the production of bitumen by oxidation
In order to optimize the composition of the raw material for the production of oxidized bitumen, it is possible to add to its composition various high-boiling petroleum products, in particular darkened vacuum distillate (DVD)

Summary

Introduction

Conventional building materials can provide an acceptable quality of work for several decades, but recently this situation has changed dramatically. There are more and more cars, the traffic intensity increases. The load on the road increases significantly. Traditional binder in the form of bitumen can no longer provide the necessary characteristics of the roadway. The specific disadvantages are as follows: high sensitivity to temperature changes; low elasticity; poor mechanical characteristics; ageing property. Over the past 30 years, research has been continuously conducted to improve the economic efficiency and practicality of using hot bitumen. To improve the technological qualities of the traditional binder, it is advisable to use polymeric materials [1]
