Abstract

The invention relates to a preparation method for a deicing, antiskid and denoising asphalt pavement material. The method is characterized by comprising the following steps: 1) preparation of rubber modified asphalt with high viscosity and high elasticity; 2) preparation of an organic / inorganic ice inhibiting material; 3) selection of mineral aggregate gradation; 4) preparation of the deicing, antiskid and denoising asphalt pavement material, which is realized by preparing mineral aggregate, the rubber modified asphalt with high viscosity and high elasticity, the organic / inorganic ice inhibiting material and fibers according to a mass ratio of 100: 4.8-5.1: 1.05-2.1: 0.225-0.533, heating the rubber modified asphalt with high viscosity and high elasticity at a temperature of 165 to 175 DEGC, and mixing and stirring the mineral aggregate, the rubber modified asphalt with high viscosity and high elasticity, the organic / inorganic ice inhibiting material and the fibers at a temperature of180 to 190 DEG C for 60 to 90 s, with paving temperature being 165 to 180 DEG C, so as to obtain the deicing, antiskid and denoising asphalt pavement material. The asphalt pavement material prepared by using the method has the characteristics of ice removal, skid resistance and noise reduction.

Description

technical field

[0001] The invention belongs to the field of material science and engineering, and in particular relates to a preparation method of an asphalt pavement material. technical background

[0002] With the rapid development of my country's transportation infrastructure, a large number of highway engineering projects have been launched one after another, and people's requirements for them are getting higher and higher. On the basis of driving safety, the demand for functionality is becoming stronger and stronger, especially for high-grade highways. highway. In the south, there is a lot of precipitation, and the use of ordinary asphalt mixture is likely to cause water accumulation on the road, and it is easy to generate water mist and glare when driving, which seriously affects the safety of driving, and many road sections must pass through residential areas. Although there are sound insulation devices The problem of driving noise still needs to be further improved;...
