Bituminous concrete material capable of reducing adhesion of snow ice on road surface and preparation method thereof

Abstract

The invention provides a bituminous concrete road surface material capable of reducing adhesion of snow ice on a bituminous road surface and a preparation method thereof, relating to bituminous road surfaces such as a freeway, a ramp, an overhead, a bridge surface and the like. The bituminous concrete road surface material comprises the following components: 107 organic silicon rubber modified bitumen, ore aggregate and ore powder. The preparation method comprises the following steps: firstly, preparing a 107 organic silicon rubber modified bitumen cement material; and then preparing an organic silicon rubber modified bituminous mixture. By utilizing a high hydrophobic bitumen film which is formed by organic silicon rubber with low surface energy on the surface of the aggregate and insidethe gap of the aggregate, the adhesion of the snow ice on the road surface is reduced, thus the snow ice is easy to eradicate.

Description

technical field [0001] The invention relates to an asphalt concrete pavement material for reducing ice and snow cohesion and a preparation method thereof, and relates to asphalt pavements such as highways, ramps, viaducts, and bridge decks. Background technique [0002] In winter, ice accumulation on asphalt concrete pavement is usually difficult to effectively remove, and traffic accidents caused by ice accumulation often lead to billions or even higher direct economic losses. In order to ensure traffic safety and avoid major accidents, during the ice disaster warning period, expressway management departments often take closed measures reluctantly, and the resulting losses are also very large. [0003] Common deicing methods include chemical deicing agents, mechanical deicing and thermal deicing. Chemical deicing methods use chemical active agents to lower the freezing point of road surface water to delay the crystallization of ice. Usually, there are alcohol deicing metho...

Problems solved by technology

Conductive pavement ice and snow melting technology refers to the addition of polymer, carbon or metal conductive admixtures to pavement pavement materials, so that highly insulating pavement pavement materials have the ability to sense and convert heat and electricity. Electric energy is converted into heat energy, and the heat energy is conducted upward through the contact surface between the pavement material and the ice and snow, so that the ice and snow absorb heat and melt. This method consumes a lot of energy
