Asphalt mixture with conductive function and preparation method thereof

Abstract

The invention discloses a preparation method of an asphalt mixture with a conductive function. The method is characterized by comprising the following steps of: (1) preparing a wear-resistant conductive material: mixing and stirring 10 to 15wt% of phenol, 8 to 15wt% of formaldehyde, 25 to 30wt% of EDOT, 5 to 10wt% of dicumyl peroxide, 5 to 10wt% of reduced graphene oxide, 3 to 10wt% of glass fibers, 2 to 8wt% of silicon nitride and the balance of water, raising the temperature to 80-95 DEG C, reacting for 4-10 hours, and then performing temperature reservation; (2) mixing asphalt and aromatichydrocarbon oil into a wear-resistant conductive material mixed solution; and (3) molding to obtain the asphalt mixture with the conductive function. The invention also provides the asphalt mixture with the conductive function, which is prepared by the method. The asphalt mixture has the properties of high conductivity, high strength and toughness, hydrophobicity, oxidation resistance, wear resistance and the like.

Description

technical field [0001] The invention relates to the field of asphalt mixture, in particular to an asphalt mixture with conductive function and a preparation method thereof. Background technique [0002] Asphalt is an organic gelling material composed of hydrocarbons of different molecular weights and their non-metallic derivatives, which has waterproof, moisture-proof and anti-corrosion properties, and has been widely used in road surface paving. However, when the existing asphalt materials are used on the road for a long time, on the one hand, oxidation and wear will occur under the action of load and natural environment, resulting in asphalt aging and road surface performance degradation; on the other hand, the insulating asphalt pavement Snow removal in winter takes too much manpower and material resources, but conductive asphalt can raise the temperature of the road surface to above zero degrees Celsius by means of electricity, so as to achieve the purpose of snow remova...
