Improving the Bitumen Quality through the Comprehensive Polymer-Based Modification

Abstract

One of the ways to improve the qualities of asphalt and concrete mixes is to modify the binding agent in its composition with polymer additives. The article presents rubber with polyethylene and vinyl acetate (sevilen) as a modifying additive to the road construction bitumen. The impact of rubber on the properties of the polymer bitumen binding agent (PBBA) was analysed. The mode of action of the complex additive was explained, the evidence-based concentration of rubber in PBBA was identified.
