Abstract

The invention relates to filling glue for filling an asphalt pavement crack. The filling glue comprises a component A and a component B, wherein the application amount of the component B is 2-5% of that of the component A; the component A comprises the following components in parts by weight: 100 parts of film forming agent, 15-30 parts of filler, 1.5-5 parts of coloring agent, 40-60 parts of modifier, 0.1-0.3 part of catalyst and 30-50 parts of plasticizer; the component B comprises 1-6 parts of crosslinking agent, 2-6 parts of tackifier and 1-5 parts of chain extender; the filler and the coloring agent are both modified by a coupling agent; and the coupling agent is any one of gamma-aminopropyltriethoxysilane, gamma-glycidyl ether oxypropyl trimethoxysilane, isopropyldioleicacyloxytitanate and isopropyltrititanate. The filling glue provided by the invention has high bonding strength, high strength, good elasticity and leveling property and good workability. The phenomena of oil stains and bleeding on the repaired pavement are avoided, and the driving safety is not influenced.

Description

technical field [0001] The invention relates to a repair and maintenance material for filling cracks in asphalt pavement, in particular to a seam-filling glue for filling cracks in asphalt pavement and a preparation method thereof. Background technique [0002] Asphalt roads in my country are mainly semi-rigid base structures, and reflective cracks are more serious. With the channelization of road traffic and the intensification of loads, the cracks of asphalt pavement are becoming more and more serious, and the damage of rainwater is also becoming more and more prominent. Subsequently, the smoothness of the road surface is reduced, the strength and stability of the roadbed are weakened, and driving safety is seriously threatened. [0003] The industry often uses modified asphalt to repair cracks, but the elastic modulus difference between the existing crack repair materials and the joint groove wall concrete is large, the low-temperature adhesion is low, and the low-tempera...
