Abstract

Belonging to the technical field of asphalt, the invention in particular relates to a superhard asphalt and a preparation method thereof. The superhard asphalt comprises the following raw materials bymass: 120-150 parts of asphalt; 10-19 parts of polyethylene; 15-20 parts of stearamide; 10-15 parts of sterin; 5-10 parts of epoxy resin; 1-3 parts of vinyl triamine; and 3-5 parts of a DH-2 reinforcing agent. The invention has the beneficial effects that: the cohesion and elasticity of asphalt are improved, the high temperature stability of asphalt can be effectively improved; and at the same time, the brittleness temperature is lowered, the tensile strength of asphalt is enhanced, the hardness of asphalt is increased, and the damage rate of highway is greatly reduced.

Description

technical field [0001] The invention belongs to the technical field of asphalt, and in particular relates to a superhard asphalt and a preparation method thereof. Background technique [0002] Bitumen is a material commonly used in the preparation of paving and roofing materials. In the road-building and road-laying industries, it is a well-established and practical method to coat aggregate materials, such as sand, gravel, crushed stone, or mixtures thereof, with hot fluid bitumen, which coats the coated material while it is still hot. Spread as a uniform layer on a subgrade or previously constructed road and compact the uniform layer by rolling with a heavy-duty roller to form a smooth-surfaced road. With the rapid development of highway construction in our country, while the mileage of highways has increased rapidly year by year, the traffic flow and heavy-duty vehicles on the highway have increased rapidly, and the wear and tear of the road surface has greatly increased ...
