Abstract

The present application discloses an anti-condensation ice composite finishing method for asphalt pavement, comprising: (a) bottom layer construction: spraying a certain amount of oily epoxy asphalt-based cement on the asphalt pavement, spreading a layer of bottom layer basalt aggregate, oily After the epoxy asphalt binder is initially set, the bottom layer is compacted, and the oily epoxy asphalt binder is cured and formed until the oily epoxy asphalt binder is consolidated; (b) Anti-freezing ice construction: sprinkle a certain amount of anti-icing agent and distribute it in the gap of the bottom basalt aggregate (c) Surface layer construction: spray a certain amount of water-based polymer-modified asphalt binder, spread a layer of basalt aggregate on the sprayed water-based polymer-modified asphalt binder, and spray the water-based polymer-modified asphalt binder. After initial setting, the surface layer is compacted; (d) Cover material construction: spray a certain amount of cover material on the surface layer, and cure and shape. The anti-condensation ice composite finishing method can improve the anti-condensation and snow melting performance of asphalt pavement.

Description

technical field

[0001] The application belongs to the technical field of road construction, and in particular relates to an anti-icing compound surface treatment method for asphalt pavement. Background technique

[0002] Solving driving safety on icy roads in winter is a difficult problem in the world today. Research on how to improve driving safety on icy and snowy roads, avoid or reduce traffic accidents, improve road capacity and operational efficiency, form a good road safety management model, and become a winter road At the same time, road icing has become an urgent problem to be solved in our country. The research and development of scientific and effective road surface deicing technology has very important social and economic value.

[0003] The methods to solve road icing are mainly divided into passive deicing and active ice suppression. Passive deicing refers to traditional snow removal and deicing methods such as mechanical removal method and thermal deicing meth...
