Effect of Deicing Salt on Road Performance of Asphalt Mixture
To ensure the normal operation of road transportation after snowfall,machinery and snow melting agents are applied for de icing and snow melting.However,snow melting agents can cause damage to the performance of asphalt mixtures and further affect the road performance of asphalt pavements.The article summarizes the impact and damage mechanism of three common types of snow melting agents on the road performance of asphalt mixtures.The results show that traditional chloride based snow melting agents have the greatest negative impact on the performance of asphalt pavement and have a significant impact on the surrounding environment;Non chlorinated snow melting agents have a relatively small impact on road performance,but their cost is high and their preparation process is complex;As a new type of snow melting salt,environmentally friendly composite snow melting agent reduces the adverse effects of the other two snow melting agents to a certain extent,providing direction and ideas for the design and development of environmentally friendly long-life anti freezing asphalt pavement.
