Abstract
Polymer-modified binders (PMB) have found wide application in improving the durability and performance properties of asphalt pavement. To establish the prospects for modifying bituminous binders with polymers, it is necessary to study the basic physical and chemical characteristics of these materials. This paper presents the results of studying the main structural and thermophysical properties of polyethylene terephthalic waste. It was revealed that the presence of functional groups and the corresponding thermal characteristics of the polymer waste open the possibility of using them as modifiers in road construction.
