Abstract

This application relates to the field of asphalt concrete, and specifically discloses a permeable high-strength asphalt concrete and a preparation method thereof. The permeable high-strength asphalt concrete comprises the following components by weight: 10-15 parts of asphalt base material, 15-20 parts of mixed aggregate, 25 to 30 parts of mineral powder, 45 to 50 parts of cement and 10 to 15 parts of reinforcing filler, the reinforcing filler includes polyester fiber and basalt fiber mixed in a mass ratio of 1:2 to 5; its preparation method includes: S1, first take Prepare the asphalt base material, then mix the mixed aggregate, mineral powder, cement and reinforcing filler according to the formula, and collect the mixture; S2, mix and mix the asphalt base material and the mixture, and then collect the permeable high-strength asphalt concrete Materials; the permeable high-strength asphalt concrete of the present application can be used for pavement of roads and bridges. It has excellent mechanical strength and water permeability, and improves the durability of permeable asphalt concrete materials.

Description

technical field [0001] The application relates to the field of asphalt concrete, more specifically, it relates to a permeable high-strength asphalt concrete and a preparation method thereof. Background technique [0002] Due to its good water permeability, permeable asphalt concrete is widely used in pavement fields such as road surfaces and bridge decks. The use of permeable asphalt concrete for pavement has the following three benefits: (1) Safety benefits: The runoff formed by rainwater on the road surface in rainy days will be weakened, and the probability of water drift will decrease as the depth of the surface structure increases. (2) Environmental benefits: The noise generated by the suction and compression of the tire and the road surface is reduced from the source, and the large gap has the effect of absorbing noise, alleviating the phenomenon of excessively high road surface temperature in summer, and alleviating the city's "heat island effect" . (3) Economic ben...
