Analysis of Engineering Performance and Environmental Impact of Asphalt Pavement Debonding and Ice Suppression Materials

Abstract

Aiming at the maladies of high labor intensity, the low efficiency of ice and snow removal, and environmental pollution in traditional ice-deicing and snow-melting methods, we successfully developed a material that can effectively reduce the adhesive force between ice and snow with the pavement, aimed at the characteristics of the road ice de-icing and snow melting. According to the evaluation index and method of de-icing performance, we determined the ratio of the three components of the film-forming component, the adhesive component, the modified ice suppression component, and the preparation technology. It has no perfect evaluation index and method for the viscosity-reducing and ice-defending materials at present, this paper further evaluates the performance of the viscosity-reducing and ice-defending materials from the aspects of ice-deicing performance, durability, and environmental performance. The results show that the viscosity-reducing and ice-defending material has good permeability and water resistance. The material still has good ice-deicing performance after seven rounds of cycle tests at the same time, indicating that it has a good slow-release performance. It is verified that the viscosity-reducing and ice-defending materials have good durability using the low-temperature accelerated test. Finally, from the analysis and evaluation of the environmental protection performance of the viscosity-reducing and ice-defending materials, the materials have no effect on the growth of plants and their average corrosion rate is much lower than the average corrosion rate of the snow melting test piece, which means that the viscosity-reducing and ice-defending materials have good environmental performance.
