Abstract

The invention discloses a kind of modified asphalt with epoxy resin and rubber powder and solidifying agent. The weight proportion of said components is as follows: asphalt 100 units, rubber powder 3- 20 units, epoxy resin 1- 5 units, solidifying agent is 15% of that of epoxy resin. The penetration, softening point, low- temperature extension and torsional elasticity are better than that of normal asphalt. The modified asphalt is sticking material, and the flowability at high temperature and extension at low temperature is good. It can be used to repair asphalt concrete road surface and slow down the reflective crack generation, and increase life length for asphalt road.

Description

technical field

[0001] The invention relates to modified asphalt used for road surface maintenance and repair, in particular to an asphalt modified by epoxy resin and rubber powder. Background technique

[0002] Semi-rigid base and cement concrete pavement have the advantages of high rigidity, abundant material sources, strong diffusion load capacity, durable use, small daily maintenance workload, and stable structure. They occupy a large proportion in my country's high-grade pavement. However, due to problems in pavement structure design, construction, maintenance, and even overloaded operation, many cement concrete pavements have entered the maintenance period. Paving the asphalt concrete surface directly on the old cement concrete pavement, or paving the semi-rigid base layer on the old cement pavement for reinforcement and then paving the asphalt concrete surface layer, is a common method to improve the old road surface and increase the bearing capacity of the pavement s...
