Abstract

The invention provides active snow melting material for asphalt pavements and a preparation method thereof. The active snow melting material can be used for mountain roads, highways, viaducts, ramps, airports, municipal roads turnings and other asphalt pavements. The active snow melting material comprises a snow melting agent, a diluent, a binder and a curing agent, and a target product can be obtained through material crushing, mixing, granulation, drying and other steps. When the last layer of the asphalt pavements is paved, the snow melting agent is added and mixed, the capillary phenomenon of the asphalt pavement capillary structure is utilized, so that air moisture is condensed into water in the capillary structure, and salt in the snow melting agent is dissolved, when the salt is dissolved in water, heat is released, meanwhile, the freezing point of the water is reduced, and the purposes of snow melt and ice resistance are achieved.

Description

technical field [0001] The invention belongs to the technical field of active snow melting, and relates to an active snow melting material for roads and a preparation method thereof. Background technique [0002] my country has a vast territory, and the winter temperature in the central and northern regions is low. In rainy and snowy weather, the road surface is very easy to freeze, which reduces the friction between the road surface and vehicles and brings a lot of inconvenience to people's traffic. The traffic accidents caused by it every year have caused great casualties and property losses to the society. [0003] At present, the practical snow removal technology can be mainly divided into two types: mechanical snow removal and snow melting salt. These two kinds of methods all will expend huge manpower, material resources, financial resources, and snow removal is untimely, and effect is poor. Regardless of whether it is snowing or not, mechanical snow removal needs to ...
