Performance Evaluation of Polymer-Modified Asphalt

Abstract

Enhanced properties and better performance of polymer-modified asphalt in comparison to regular one made it a promising and attractive option in the field of pavement engineering. Since polymer additives result in increased resistance to such issues as rutting, cracking, and fatigue, thereby improvement of physical and mechanical characteristics make Polymer-modified asphalt a reliable solution for extreme weather conditions and high-traffic. Moreover, better performance results in not only increased durability but also safety of roadways, especially in districts that are prone to high loadings and large temperature fluctuations.

In order to optimize PMA additives researchers had to investigate a variety of polymers and binders, as well as different types of methodologies to make assessments and comparisons of their performance because the selection of an appropriate evaluation technique that can comprehensively describe polymers’ behavior remains a challenge. The main goal of this study is conducting a comprehensive analysis and comparison of approaches that were used in earlier studies to evaluate PMA’s performance. Also, to assess strong and weak sides of current methodologies, suggesting optimized evaluation and  application of polymer mixed asphalt in pavement construction.  The usage of sustainable materials - like recycled polymers and recovered asphalt - will also be covered in this research paper. As the road construction industry shifts to more ecologically friendly options, these materials are widespread lately
