About this document
EVA Copolymers by lucas is a document available to read on EtoBox.
The document summarizes research on modifying road bitumen with ethylene-vinyl acetate copolymers (EVA) of different molecular weights and vinyl acetate contents. EVA was introduced into heated bitumen in particulate form. The addition of EVA was found to form a three-dimensional structural grid that improves the physicochemical properties of bitumen, such as increasing softening temperature and reducing penetration depth. The highest impact was seen with a EVA of molecular weight 25,000, which extended the
