Abstract

The invention relates to a conductive slurry seal material and a preparation method and a paving technology thereof, and belongs to the field of road engineering. The conductive slurry seal material comprises the following components in percent by mass: 65-85% of aggregates, 3-8% of graphite, 0.5-2% of carbon fiber, 2.5-5% of emulsified asphalt, 2-6% of water, 0.5-1% of cement and 2-4% of epoxy resin A and B components, wherein the particle size of the used aggregate is 2.36-4.75mm. The paving thickness of the conductive slurry seal material during construction is 6-8mm. The conductive slurryseal material provided by the invention has high heating efficiency, is convenient to construct, is suitable for paving a conductive snow-melting and deicing structural layer of a newly-built road andan old road surface, and improves the driving safety on the road in winter.

Description

technical field [0001] The invention relates to a material design and preparation method of a slurry seal layer with a conductive function, which is mainly used in the field of road engineering, in particular to a conductive slurry seal layer material and a preparation method thereof. Background technique [0002] Ice and snow on the road in winter will have a serious adverse effect on the smoothness of the road and driving safety. The braking distance of a car on icy roads is 6 to 7 times that of dry roads, and it is easy to cause the vehicle to skid or roll over. Among all traffic safety accidents, the accidents when the road area is snowed and frozen are 5 to 10 times that of dry roads. According to data, the adhesion coefficient of asphalt pavement is about 0.6 in dry state, 0.2 in snow state, and only 0.15 in icy state. Therefore, on ice and snow roads, cars are prone to skidding, deviation and other phenomena, the braking distance is significantly extended, the opera...
