In order to prepare conductive asphalt concrete with good electrothermal performance,graphene-carbon fiber(rGO-CF) was used as the conductive phase material.The heat transfer principle of melting snow and ice of the concrete,and analyzed the calculation method of the heat generation and transfer during the snow melting and ice melting process.The Marshall test piece of the concrete was subjected to a temperature increase test,and the optimal rGO was determined according to the cost and the heating efficiency.The dosage was 0.5wt%,and the CF dosage was 0.3% of the aggregate mass.Under this dosage,the heating test and the snow-melting and ice-melting test were conducted on the concrete specimens.And the structure of the concrete was designed and analyzed its feasibility.
