Description

The invention relates to road building materials and can be used for the preparation of asphalt concrete mixtures for road paving.

The purpose of the invention is the disposal of waste.

A baking agent is prepared by mixing oil bitumen heated to 160 ° C with a biostimulator production waste — a dry oxidative composition of peat suspension with hydrogen peroxide. This waste has the following composition. The content of components,% by weight of organic residue:
