Main Article Content
Abstract
An analysis was made of the possibility of using sludge from the production of sulfonate additives and low molecular weight polyethylene for the modification of bituminous materials. It has been established that the combined effect of the components of the proposed combined additive on the structure of the bituminous binder makes it possible to increase its heat resistance, plasticity and elasticity, with acceptable adhesion to the surfaces of mineral materials. Modification of road bitumen with a combined additive based on sludge from the production of a sulfonate additive and low molecular weight polyethylene will expand the range of polymer modifiers for polymer-bitumen compositions, reduce the involvement of imported additives, reduce the burden on the environment and obtain a positive economic effect.
