Problems solved by technology

The shortcomings of these current snow removal methods are: 1. The power of infrared heating and resistance heating methods is too high and the cost is too high, which is incompatible with the national energy-saving policy; Low, resulting in extremely low snow removal efficiency
Furthermore, under the common frequency of microwaves used, the thickness of the heating is about ten centimeters, and more energy is wasted in the depth of the road surface, so that the energy of the surface layer of the road surface is insufficient, resulting in energy waste and restricting the efficiency of ice and snow removal

Abstract

The invention relates to a composite asphalt pavement material for removing snow and a paving method for a composite asphalt pavement. The pavement material comprises a component A and a component B. The component A is made of, by weight, 40% of coarse aggregate, 26% of fine aggregate, 8% of base asphalt, 7% of additive, 8% of graphite, 4% of junked tire powder, 4% of brass mineral powder, 0.5% of stabilizer, 0.5% of antioxidant and 2% of assistant. The content of graphite in the component B is twice that of the graphite in the component A. The pavement of an A-B-A structure is adopted, the strength of a traditional asphalt pavement paved by the same material is improved, and the snow removing efficiency is improved; the recycled waste plastic can be used, and good economic benefits and the environment-friendly function are achieved; the pavement has the advantages of being good in stability and aging resistance, good in low-temperature cracking preventing performance, adaptive to cold temperature difference areas, and long in service life; the pavement can be easily processed and formed according to construction conditions, and field road construction operation is sample; the pavement is free of pollution, resistant to corrosion and environmentally friendly.

Description

technical field [0001] The invention relates to the technical field of road engineering construction, in particular to a composite asphalt pavement material for snow removal and a laying method for the composite asphalt pavement. Background technique [0002] Transportation is an important factor to measure the development of national economy. In northern my country and high-altitude areas, winter generally lasts for a long time, and the amount of snowfall is large. Floating snow, snow, and ice accumulate on the road surface, which has a serious impact on the transportation industry and personal safety. In order to respond to the national development strategy and narrow the gap between the rich and the poor, we must first overcome the existing transportation problems and improve the current situation of the existing transportation industry. [0003] The traditional snow and ice removal methods include physical, chemical and mechanical methods. These snow removal methods hav...
