The Weakening Effect of the Snow-Melting Agent on the Performance of Municipal Asphalt Pavement in the Severe Cold Region

Abstract:

According to the phenomenon that the road would get frozen during the severe cold region in the high latitude area of Inner Mongolia, this paper study on low temperature crack resistance indexes of the asphalt pavement-the bending stiffness modulus, changing rules of stiffness modulus that is the low temperature anti-crack property index of the asphalt pavement, and bending failure characteristic. The rule changes with the density of the commonly used Chlorine salt snowmelt agent changes. Then the paper analyses how does the Chlorine salt snowmelt agent exert influences on the two kinds of aggregates of bituminous concrete. Finally, it is concluded that the snow-melting agent can weaken the performance of the asphalt pavement. The existing snow-melting agent will be replaced by Affordable and efficient pollution-free deicing in the future.
