Low-dosage stainless steel microfilament conductive asphalt concrete electric heating ice and snow melting pavement
The invention discloses a low-dosage stainless steel microwire conductive asphalt concrete electric heating ice and snow melting pavement, and belongs to the field of research and development of intelligent and functional pavement materials. According to the method, the stainless steel microwires are doped in a mode of firstly mixing the stainless steel microwires with asphalt and mineral powder, and a voltage pre-applying mode and a three-piece electrode arrangement mode which are designed on the basis of a conductive mechanism are adopted; the conductive asphalt concrete can be endowed with excellent electric conduction and heat conduction performance on the basis of ensuring excellent mechanical and deformation performance of a traditional pavement structure material, namely asphalt concrete, so that when the conductive asphalt concrete is connected with an external power supply, the conductive asphalt concrete can be heated through electro-thermal conversion according to the Joule's law, and self ice and snow melting of a pavement is realized. The electric heating ice and snow melting pavement with the low mixing amount of the stainless steel microfilament conductive asphalt concrete can be directly applied to road sections with serious snow accumulation such as airfield runways, parking lots, bridge decks and tunnel entrances in the forms of conductive asphalt concrete full-size pavement, strip type pavement and overlay.
