The invention relates to the technology for preparation of astringent for the highway engineering and can be applied in by-product-coking industry and highway engineering. The process is realised by mixing of coal-tar pitch and the additive by heating to the temperature of 60-80°C. The mixture of sour pitch of collecting and sour pitch of crude benzol distillation in the ratio 1:(0.6+0.8) is used as an additive. The additive agent is introduced into coal-tar pitch in the amount of 25+30 mass %, and the obtained composition is incubated during 15-20 minutes at 60-80°C and additionally is neutralized to the pH 3+4.
