▎ 摘　　要

NOVELTY - A graphene-based modular self-melting snow pavement comprises a modular multi-phase material composed of multiple modular self-melting snow pavement units, which comprise a base plate, a lower asphalt layer, a graphene conductive asphalt layer, an electrode, an insulating asphalt layer, and a surface layer. The material of the base plate is lean concrete. The base plate is provided with continuous grooves along the transverse direction or the longitudinal direction. The lower asphalt layer is poured into the groove and bonded by an emulsified asphalt adhesive. The graphene conductive asphalt layer is arranged on the surface of the lower asphalt layer, and is bonded by the asphalt adhesive. The electrodes are arranged at intervals in the graphene conductive asphalt layer, and are arranged along the thickness direction of the graphene conductive asphalt layer. The insulating asphalt layer is adhered on the upper surface of the graphene conductive asphalt layer. USE - Graphene-based modular self-melting snow pavement. ADVANTAGE - The graphene-based modular self-melting snow pavement has excellent high-temperature stability, water stability, fatigue resistance, crack resistance, and conductivity. DETAILED DESCRIPTION - A graphene-based modular self-melting snow pavement comprises a modular multi-phase material composed of multiple modular self-melting snow pavement units, which comprise a base plate, a lower asphalt layer, a graphene conductive asphalt layer, an electrode, an insulating asphalt layer, and a surface layer. The material of the base plate is lean concrete. The base plate is provided with continuous grooves along the transverse direction or the longitudinal direction. The lower asphalt layer is poured into the groove and bonded by an emulsified asphalt adhesive. The graphene conductive asphalt layer is arranged on the surface of the lower asphalt layer, and is bonded by the asphalt adhesive. The electrodes are arranged at intervals in the graphene conductive asphalt layer, and are arranged along the thickness direction of the graphene conductive asphalt layer. The insulating asphalt layer is adhered on the upper surface of the graphene conductive asphalt layer. The surface layer is paved on the insulating asphalt layer. A joint exists at the junction of the graphene conductive asphalt layer in two adjacent modular self-melting snow pavement units. Conductive phase change joints are cast in the joints. The graphene conductive asphalt layer consists of 4-10 pts. wt. asphalt, 70-125 pts. wt. aggregate, 12-18 pts. wt. mineral powder and conductive materials. The conductive material is composed of graphene oxide-carbon fiber composite material and steel fiber composition. The addition amount of graphene oxide-carbon fiber composite material is 5.3-15.8% of the mass of asphalt. The amount of steel fiber added is 1.5-3% of the mass of asphalt.
