Problems solved by technology

This technology has a certain effect when the temperature is higher than -2°C and the thickness of the ice layer is less than 2mm, but when the temperature is below -12°C and the thickness of the ice layer is greater than 10mm, the destructive power to the ice layer is extremely small and cannot effectively break the ice
In addition, the above-mentioned snow melting and deicing technology has no effect on improving the friction coefficient of the treated watery road surface, and there are still great hidden dangers to driving safety on rainy and snowy roads.

Abstract

The invention discloses an efficient snow-melting and deicing pavement wearing layer material and a preparation method thereof. The efficient snow-melting and deicing pavement wearing layer material is composed of three components A, B and C in a mass ratio of 100:(20-60):(150-350), wherein the component A is composed of epoxy resin, an elastic modifier, an epoxy active diluent, a snow-melting agent, a defoaming agent and a dispersing agent; the component B is composed of an epoxy curing agent, a curing accelerator, a coupling agent and pigment; and the component C is composed of waste rubber powder, waste rubber particles, magnetic iron powder and crystal whiskers. The efficient snow-melting and deicing pavement wearing layer realizes efficient snow melting and deicing under the synergistic effects of four ways, namely adoption of a snow-melting agent, strain icebreaking, strain heat release and microwave radiation heating. Compared with the prior art, the efficient snow-melting and deicing pavement wearing layer material has numerous advantages of low energy consumption, low cost, convenience in construction and maintenance, high snow-melting and deicing efficiency, environmental friendliness and improved pavement traveling safety and has broad application prospects.

Description

technical field [0001] The invention belongs to the technical field of pavement functional materials, and in particular relates to a high-efficiency snow-melting and deicing pavement wearing layer material and a preparation method thereof. Background technique [0002] Transportation is the main artery of the national economy, and snow and ice on roads seriously affect traffic safety and traffic efficiency, and are one of the important restrictive factors for economic development in high-cold and high-cold regions. Snow and icing lead to a significant decline in the anti-skid performance of the road surface, which is extremely detrimental to the driving dynamics and safety of the vehicle. How to effectively solve the problem of not closing the road or reducing the road closure in ice and snow days, avoiding traffic accidents or less traffic accidents, and forming a good The safe management mode of traffic management has become one of the important tasks of the traffic manage...
