Abstract

The invention belongs to the technical field of asphalt pavement crack repairing, in particular to an asphalt pavement crack repairing binder and a highway crack repairing adhesive tape prepared by the binder. The asphalt pavement crack repairing binder of the invention takes asphalt matrix, rubber powder, thermoplastic elastomer, cryogenic regulator, high temperature regulator, filler and hardness regulator as raw materials. The prepared asphalt pavement crack repairing binder has good adhesion, high-temperature flowing resistance and low-temperature cracking resistance, and the low-temperature resistance can resist 35 DEG C cold environment.

Description

technical field [0001] The invention belongs to the technical field of asphalt pavement crack repairing, and in particular relates to an asphalt pavement crack repairing adhesive and a road crack repairing adhesive tape prepared therefrom. Background technique [0002] With the rapid growth of the national economy, my country's highway construction has entered a good development period. The achievements of expressway construction are astounding. Asphalt pavement has been widely used in various highways and urban roads because of its advantages such as smooth driving, comfortable driving, low noise, convenient maintenance and recyclable utilization. At present, more than 90% of the expressways in our country are asphalt pavement. [0003] However, during the use of asphalt pavement, due to the rolling and friction of automobile tires and other vehicles, and the coupling effect of complex environment and heavy traffic load, pits and cracks will appear prematurely on the asph...
