Problems solved by technology

[0004] However, general asphalt has average frost resistance. When used in cold regions, its structural strength is likely to decrease due to low temperature. Moreover, because permeable asphalt has many pores, once its structural strength decreases, it is more likely to be damaged by external forces. , resulting in affecting the use of pavement, therefore, there is still room for improvement

Abstract

The invention relates to the technical field of asphalt materials. Aiming at the problem that the structural strength of the asphalt is likely to decrease due to too low air temperature, a water-permeable asphalt is provided. 380-410 parts of material; 90-120 parts of fine aggregate; 3-5 parts of thiamethoxam; 0.5-1.5 parts of polyacenaphthylene. Also provided is a method for preparing water-permeable asphalt, comprising the following steps: S1. heating the asphalt to 170°C-180°C, adding thiamethoxam and polyacenaphthylene, and stirring evenly to form a premix; S2. adding fine powder to the premix Aggregate, stir evenly to form a fine mixture; S3. Add coarse aggregate to the fine mixture, stir evenly to form permeable asphalt. By adding thiamethoxam and polyacenaphthene to the permeable asphalt and mixing it with the asphalt in a specific ratio, the antifreeze performance of the asphalt is effectively improved, and the brittle point of the permeable asphalt is reduced, so that it is not easy to cause permeable asphalt due to temperature drop in cold regions The strength of the road is reduced, which makes the road structure more stable and improves driving safety.

Description

technical field [0001] The invention relates to the technical field of asphalt materials, in particular to a permeable asphalt and a preparation method thereof. Background technique [0002] Asphalt is often used to pave roads, and as the requirements for road drainage become higher and higher, permeable pavements emerge as the times require, and permeable pavements are usually paved with permeable asphalt. [0003] Permeable asphalt is an asphalt mixture with large porosity. By adjusting the ratio of coarse aggregate to fine aggregate, there are more gaps between coarse aggregates, so that permeable asphalt has large porosity to achieve water permeability. [0004] However, general asphalt has average frost resistance. When used in cold regions, its structural strength is likely to decrease due to low temperature. Moreover, because permeable asphalt has many pores, once its structural strength decreases, it is more likely to be damaged by external forces. , leading to the ...
