Problems solved by technology

This method has poor stability, and the salt substances are easily washed away by rainwater and lost in large quantities.
On the non-arterial roads of urban roads, it is mainly relying on manual snow removal and ice breaking at present. However, with the increase of car ownership and the increase of expressways, tunnels and bridges, it is difficult to meet people's travel requirements only by manual snow removal. Ice and snow gradually tend to be mechanized and automated, reflecting technical characteristics such as safety, speed, and environmental protection

Abstract

The invention provides a micro-surfacing mixture with the snow-melting function. The micro-surfacing mixture is prepared from, by weight, 73.5-74.5 parts of aggregates, 8-9 parts of SBR (styrene butadiene rubber) modified emulsified asphalt, 4-5 parts of mineral powder, 7-9 parts of water, 1.2-1.8 parts of cement, 1-4 parts of microencapsulated phase change materials and 1-4 parts of an acetic acid type snow-melting agent, and the aggregate grading type of the micro-surfacing mixture is MS-3 type. The invention further provides a method for preparing the micro-surfacing mixture with the snow-melting function. By the arrangement, deicing or snow-melting function can be achieved on snow-ice covered roadway, active snow-melting function of the roadway is achieved, the deicing and snow-melting problem in winter can be effectively solved, simpleness in preparation is achieved, and wide actual application value is realized.

Description

technical field [0001] The invention belongs to the technical field of road pavement, and in particular relates to a micro-surfacing mixture with snow-melting function and a preparation method thereof. Background technique [0002] After many years of driving on the existing asphalt concrete pavement and cement concrete pavement in our country, a considerable part of the pavement has a variety of surface functional diseases although the overall structural strength is intact. For the maintenance and repair of this part of the pavement structure, from the perspective of reducing the impact on the pavement elevation and saving resources, it is only necessary to restore its surface function, and the use of micro-surface maintenance technology is an ideal solution, and in preventive maintenance Or in new roads, the micro-surface can also function as a surface wear layer, so the micro-surface mixture has been widely used in road surface preventive maintenance. [0003] In winter,...
