MODIFICATION OF BITUMINOUS BINDING ADDITIVE MALEIC ANHYDRIDE
The article discusses the relevance of using a polymer-bitumen binder, and also shows the numerous advantages of polymer-modified bitumen in comparison with unmodified ones (durability, crack resistance, rutting resistance, elasticity, etc.). The results of experiments are presented, in which the dependences of the quality indicators of the polymer-bitumen binder on the ratio of reagents obtained by the reaction with maleic anhydride at 150°C for 2 hours and secondary low-density polyethylene at 180°C were revealed.
