[0073] A kind of asphalt mixture is characterized in that: comprising asphalt, gravel, waste tire particles, basalt fiber and mineral powder, in parts by weight:

[0074] Asphalt: 25 parts

[0075] Gravel: 3 servings

[0076] Waste tire pellets: 12 parts

[0077] Basalt fiber: 22 parts

[0078] Mineral powder: 2 parts.

[0079] The particle size of the gravel is 3 mm, the particle size of the waste tire is 3 mm, the basalt fiber is short basalt fiber, and the particle size of the mineral powder is 0.5 mm.

[0080] Particle size refers to the size of particles, usually the particle size of spherical particles is expressed by diameter, and the particle size of cubic particles is expressed by side length. For irregular mineral particles, the diameter of a sphere that has the same behavior as the mineral particle can be taken as the equivalent diameter of the particle.

Abstract

The invention discloses an asphalt mixture, which is prepared from 15 percent to 32 percent of asphalt, 8 percent to 14 percent of gravel, 9 percent to 14 percent of waste tire particles, 45 percent to 64 percent of basalt fiber and 4 percent to 7 percent of powdered ore in percentage by weight. The basalt fiber is added into the asphalt mixture for improving the intensity, the high-temperature-resistant and low-temperature-resistant performance of the asphalt mixture; the pavement made of the asphalt mixture cannot be damaged by ice and snow weather in northern area and the exposure in the sun in south area; the pavement flatness is high; tracks cannot be left; the potential safety hazards caused by tracks are eliminated.

Description

technical field [0001] The invention belongs to the field of road and bridge construction, in particular to an asphalt mixture used as a highway pavement. Background technique [0002] There are asphalt pavement and cement pavement on highways or urban street roads. Asphalt pavement has little friction on tires, but it is softened by heat in hot weather, and ruts are formed after the car is rolled, and asphalt is bonded to the tires. First, it is easy to cause traffic accidents. , but more damage to the tires. However, the cement road has a large friction to the tires, a large wear and tear on the tires, and the cost is relatively high. [0003] Therefore, asphalt mixture is mostly used for the road surface laid now. The existing asphalt mixture can be divided into two categories: petroleum asphalt and coal asphalt according to the different binders used; some countries or regions also use or mix it. Mixed with natural asphalt. According to the different types of aggregat...
