Abstract

The invention discloses a direct-casting type anti-track agent, which is formed by the following components by weight in mixing mode: 20 to 40 parts of regenerative polyolefine plastic, 10 to 20 parts of regenerative polyester plastic, 2 to 10 parts of regenerative wax, 2 to 10 parts of organic powder body with small particle size and 5 to 10 parts of gilsonite. A preparation method of the direct-casting type anti-crack agent and a method for preparing asphalt mixture by adopting the direct-casting type anti-crack agent are further disclosed. Particles of the direct-casting type anti-crack agent can be directly cast in hot aggregate on construction sites to be mixed with the hot aggregate in drying mode, intermittent construction can be conducted, and the direct-casting type anti-track agent lowers or reduces probability of separation of modified asphalt in the cooling, transporting and storing processes, and break through limit and restraint brought by continuous production and construction.

Description

Technical field

[0001] The invention belongs to the field of composite polymer materials, and relates to a direct-investment type anti-rutting additive (brand name: Liqiang) that can improve the anti-rutting ability of an asphalt mixture pavement, a preparation method thereof, and preparation of asphalt by using the direct-investment type anti-rutting agent Mixing method. Background technique

[0002] With the continuous improvement of my country's economic level, the demand for motor vehicles has increased sharply and the types of diversification have promoted the vigorous development of the asphalt road industry. Correspondingly, the requirements for the performance of asphalt roads are getting higher and higher. Under external conditions such as the increase of heavy-load vehicles and the deterioration of climatic conditions, how to prevent and reduce asphalt pavement diseases has become another hot spot for road construction, maintenance and research workers. Among the many...
