METHOD FOR APPLYING IMPREGNATING COMPOSITION BASED ON BITUMEN FOR TREATMENT OF ASPHALT CONCRETE PAVEMENTS

摘要

FIELD: road construction.;SUBSTANCE: invention relates to the field of road construction. The method for accelerating the hardening of a water-based bitumen-containing impregnating composition on a road surface includes the following steps: the surface of the laid road surface is cleaned of dirt, then a water-based bitumen-containing impregnating composition without solvents is applied to the surface of the road surface and leveled with a thin uniform layer, in the period from the moment of application of the specified impregnating composition and until it is completely dry, an aqueous solution containing CaCl2 is sprayed over the impregnating composition, which causes rapid polymerization of the impregnating composition. The invention is developed in the subclaims. ;EFFECT: simplification of the technology of laying a protective road surface and reduction of its drying time to a condition suitable for use.;6 cl
