Freezing-proof bituminous mixture as well as preparation method and construction method thereof

Abstract

The invention relates to a freezing-proof bituminous mixture as well as a preparation method and a construction method thereof, and belongs to the field of engineering technology. According to the invention, Mafilon is added into a bituminous mixture, so that the problem that bituminous pavement freezes in winter is solved, and the freezing point of the frozen pavement can be lowered to relieve freezing of the pavement in winter. The preparation process of the freezing-proof bituminous mixture is simple and convenient, so that the service performance of the bituminous mixture is ensured, and the effect of reliving the freezing of the pavement is achieved. According to the invention, the freezing temperature of the pavement can be lowered to about -3 DEG C to -5 DEGC; a pavement of a place with large snowfall is more easily subjected to snow removal as compared with a common pavement, and a great quantity of human, material and financial resources are reduced; the mixture contains components for relieving freezing, so that the effect of preventing accidental freezing is achieved; the driving safety of a car on the pavement can be improved in winter, and traffic accidents are reduced; compared with the common method for removing ice through spilling salt and the like, the ice removing method adopting the bituminous mixture has the advantages that nearly no damage to the environment is caused, a pavement method for protecting ecology is realized, and the pollution to the environment is reduced; the cost for the management and maintenance of the pavement in winter is lowered, and the better economical efficiency is achieved.

Description

technical field [0001] The invention relates to an antifreeze asphalt mixture and its preparation and construction method, in particular to the preparation of Mafilon antifreeze asphalt mixture and its construction method, and belongs to the field of engineering technology. Background technique [0002] At present, asphalt pavement is the main pavement type of expressways in my country, and has been widely used in major roads such as airport runways, bridge deck pavement, expressways, and urban roads, and most of the various pavement projects under construction are also made of asphalt pavement. However, most areas of our country have freezing phenomena in winter, and the problem of seriously affecting road smoothness and driving safety has become increasingly prominent. Snow and ice on the roads in winter will cause the airport to be closed and shut down, the expressway to be restricted and interrupted, and even cause serious traffic accidents, causing huge losses to people...

Problems solved by technology

However, salt spraying has brought many negative effects to the concrete pavement structure and the environment, mainly manifested in problems such as steel fiber corrosion, pavement peeling damage, and environmental pollution.

Many countries in the world have caused serious damage to roads and bridges due to the use of snow removal salt, and are currently spending huge sums of money on repairs, resulting in huge economic losses

The method of cable heating to melt snow and ice is difficult to construct and lay out, and once a problem occurs in the cable, it will take a lot of work to find the problem and maintain the line, and the cost will be high
