Study on Effect of Freeze-thaw Conditions on Epoxy-based Permeable Surface Layer
In order to explore the evolution law of the properties of epoxy permeable surface layer under the condition of freeze-thaw cycle,the appearance,quality loss and strength degradation were taken as evaluation indexes,and the freeze-thaw cycle test was carried out.The results indicate that the epoxy-based porous pavement layers showed a relatively low mass loss rate of less than 0.1%,which is far below the required performance standards,after 30 freeze-thaw cycles.The strength degradation rate of the layer was relatively high,but the loss rate of compressive strength was around 10.85%,which is lower than the specified requirement of 20%.Overall,the experiment results suggest that epoxy-based porous pavement layers exhibit better freeze-thaw resistance.
