Abstract

The invention discloses an asphalt pavement crack pouring material. The asphalt pavement crack pouring material is prepared from the following raw materials: 64 to 83 percent of matrix asphalt, 4 to 9percent of rubber powder, 1 to 2 percent of red brick powder, 2 to 5 percent of iron trioxide powder, and 10 to 20 percent of biomass oil. The asphalt pavement crack pouring material which is solid at a normal temperature can be rapidly changed to an injectable liquid material by virtue of a microwave heating way, so that the environmental pollution caused by the harmful gas generated by the traditional material and method can be avoided, and the material aging caused by the repeated heating of the traditional crack pouring material can also be overcome.

Description

technical field [0001] The invention belongs to the technical field of road engineering, and in particular relates to an environment-friendly asphalt pavement joint filling material. Background technique [0002] Asphalt pavement is exposed to the natural environment for a long time. Under repeated traffic loads, pavement diseases such as transverse joints, longitudinal joints and network cracks often appear, which seriously reduce the service quality and service life of the road. At present, the main treatment measures adopted by our country for the above-mentioned diseases are to use hot asphalt to seal the cracks, that is, to implement crack filling treatment. This treatment method can effectively alleviate the development of asphalt pavement cracks, and is a very effective technical means. The traditional asphalt pavement filling technology specifically refers to heating and softening asphalt at room temperature, and then pouring it into a huge iron container. The cont...
