摘要
The research aims at the preparation and characterization of a functional porous ultra-thin friction course (PUFC) with recycled steel slag as aggregate. At first, the PUFC was designed by modified Bailey method and Particle interference theory, and selected through the Technique for Order Preference by Similarity to an Ideal Solution (TOPSIS) method with index of weight. Then the resistance to dynamic water damage of PUFC was characterized byMoisture Induced Sensitivity Tester (MIST). Meanwhile, the SWMM software was used to simulate drainage performance of PUFC under different rainstorm intensities in Wuhan. Finally, the induction heating efficiency, self-healing property and snow and ice melting property of PUFC with steel wool fibers were investigated. The results demonstrate the PUFC gradation with pores ratio of 21.2% presents the best durability performance. The factors of cycles, temperature, and pressure during the dynamic water damage processing will conduct the weaken impact on the mechanics of PUFC, particularly the temperature. It is also found that the PUFC has the capacity to reduce the runoff, but there is a limitation to this reduction which is 10a of the return period. Furthermore, PUFC with steel wool fibers can be inductively heated, which helps to heal the cracks inside PUFC meanwhile also melt the ice and snow on the surface. Thus, the PUFC can be effectively prepared and its performance of self-healing, drainage, and snow and ice melting contribute its applicability in sponge city engineering.
