<p>Ethylene-vinyl acetate copolymers having a melt index of 700-10000 and a vinyl acetate content of from 1-40% by weight (based on the copolymer) are used as components of bitumenous binder compositions for the surface dressing of roads to improve the temperature range of their operability, the particular EVA's are also found to have good compatibility with the types of bitumen used.</p> |
