Asphalt concrete pavement material composition capable of absorbing microwaves

Abstract

The invention discloses an asphalt concrete pavement material composition capable of absorbing microwaves. The composition is prepared from the following raw materials in parts by weight: 10-15 partsof pyrite slag powder, 5-10 parts of carbon fiber powder, 2-6 parts of taconite powder, 1-2 parts of magnetite ore powder, 2-5 parts of quartz sand powder, 0.2-0.5 part of manganese dioxide, 30-40 parts of asphalt, 5-8 parts of limestone ore powder, 0.2-0.3 part of aluminum oxide, 0.1-0.2 part of nickel oxide, 0.2-0.4 part of cobalt oxide and 4-6 parts of copper ore powder; the carbon fibers, thecopper ore powder and iron ore substances such as the pyrite slag powder in the component materials have stronger thermal conductivity and microwave absorption capacity, wherein the carbon fibers cannot only improve the mechanical property parameters of the asphalt concrete pavement materials and improve the tensile strength, but also have higher microwave absorption capacity, so that the absorption capacity of the pavement material to the microwaves can be effectively improved after the carbon fibers are added into the asphalt concrete pavement material composition.

Description

technical field [0001] The invention relates to the technical field of road pavement materials, in particular to a microwave-absorbing asphalt concrete pavement material composition. Background technique [0002] Snow often freezes on asphalt roads in winter. In this kind of weather, vehicles are facing great difficulties in driving, and traffic accidents are extremely prone to occur. Therefore, the ice and snow on the road must be removed in time. At present, methods such as machinery and chemicals are commonly used to clear road ice and snow, but there are many problems that mechanical deicing will cause damage to the road surface, and may not be able to completely remove ice and snow; while chemical deicing is better, but it will damage the road. 1. Corrosion of bridges will reduce the service life. At the same time, chemicals may enter rivers and lakes with melted ice and snow, pollute water sources and damage vegetation. Due to the different properties of the road sur...
