Abstract

The invention relates to graphene asphalt concrete and a preparation method thereof, which solves the technical problems that a paving material in the prior art is liable to damage, and automobile tail gas cannot be treated. The graphene asphalt concrete is prepared from the following raw materials in parts by weight: 300-500 parts of aggregates, 40-60 parts of asphalt, 50-80 parts of slag powder,10-30 parts of graphene oxide, 10-30 parts of titanium dioxide and 3-5 parts of carbon fibers. The invention further provides a preparation method of the graphene asphalt concrete. The graphene asphalt concrete is widely applied to the technical field of road engineering.

Description

technical field [0001] The invention relates to the technical field of road engineering, in particular to a graphene asphalt concrete and a preparation method thereof. Background technique [0002] With the development of my country's industrial construction, roads have also become a necessary condition. Especially the development of asphalt pavement. Compared with cement pavement, asphalt pavement has smooth surface, comfortable driving, small vibration, low noise, short construction period, convenient maintenance and repair, and is suitable for phased construction. However, due to large vehicles and long-term operation, the road surface is extremely easy to cause damage, and is prone to problems such as large and small pits, ruts, cracks and frost cracks. Therefore, we urgently need a paving material with high rolling strength to solve this problem. [0003] In recent years, with the rapid development of the motor vehicle economy, the production and use of motor vehicles ...
