MATERIAL FOR RESTORE OF ASPHALT CONCRETE PAVEMENT Russian patent published in 2006 - IPC C08L95/00 

FIELD: sealing materials.

SUBSTANCE: invention relates to technology for manufacturing penetrating sealing agents. The material for restore of asphalt concrete pavement by impregnation comprising bitumen, solvent and additive involves vinyl-trimethoxysilane and/or octyl-triethoxysilane and natural and/or oil-polymeric resins and wherein solvent is chosen from the group involving toluene and/or benzene, and/or kerosene, and/or nefras, and/or solvent, and comprises also tetrabutoxy-titanium as a catalyst in the following ratio of components, wt.-%: vinyl-trimethoxysilane and/or octyl-triethoxysilane, 5-15; tetrabutoxy-titanium, 0.1-0.15; natural and/or oil-polymeric resins, 10-20; solvent, 40-50, and road bitumen, the balance. Proposed material provides deformability, heat resistance and simultaneously protection of asphalt concrete pavements against water and frosty destruction, inhibits filtration of water in asphalt concrete structure, provides protection of asphalt concrete and constructive layers of road pavements from surface water and can be used in building and repair of road pavements.

EFFECT: improved and valuable technical properties of material.
