Study on Deicing Mechanism of High-elastic/salt-storage Functional Pavement

Snow and ice on pavement surface will reduce anti-skid performance between tire and pavement which will cause traffic safety problem. High-elastic/salt-storage asphalt mixture is a recently widely used functional pavement for snow removal and ice melting. In this paper, a three-dimensional finite element model of pavement structure under five different working conditions is established. Then, the pavement structure under the most unfavorable conditions can be determined through calculating and analysing for the maximum compressive strain index in the ice layer. And the sensitivity of the ice melting effect parameters including ice thickness, temperature, thickness and modulus of high elastic pavement with salt storage were respectively discussed under the most unfavorable conditions.
