Problems solved by technology

[0003] First of all, in view of the current domestic heating-type caulking adhesive market, due to the price, the products are uneven, and the fluidity is often poor during use, and the cracks cannot be effectively filled, resulting in false cracks; or insufficient adhesion and warping Or the phenomenon of secondary cracking due to the poor rebound and tensile properties of the material; or the high construction temperature causes a large amount of energy consumption; or the construction is greatly affected by the climate
[0004] Secondly, for the repair subsidy, through market research, it is found that there are also some problems with the seam tape, such as the phenomenon of warping and taking away due to insufficient viscosity; the car jumping phenomenon occurs due to the layer of glass fiber cloth, which affects the driving comfort; When fire is required in the process of use, it will affect the construction efficiency
[0005] Finally, for excavation and repairing, the construction cost is high, the construction is complicated, and the repair speed is slow. At the same time, it will cause environmental pollution and waste of resources due to excavation and repairing.

Description

technical field [0001] The invention relates to the technical field of road engineering materials, in particular to a high-temperature-resistant and low-temperature-resistant pavement gap repair subsidy. Background technique [0002] During the use of asphalt pavement, due to the repeated effects of external factors such as climate and load, different types of diseases appear on the pavement. Among them, pavement cracks are relatively common. At present, the method of treating asphalt pavement cracks mostly uses heating type joint glue , repair subsidy or excavation for processing. [0003] First of all, in view of the current domestic heating-type caulking adhesive market, due to price reasons, the products are uneven, and the fluidity is often poor during use, and the cracks cannot be effectively filled, resulting in false cracks; or insufficient adhesion and warping Or the phenomenon of secondary cracking due to the poor rebound and tensile properties of the material; or...
