摘要：AbstractThis paper presents a new treatment to icy road, anti-sliding layer with hot melting macadam. Experiments were done to investigate the different factors influencing the effect of hot melting macadam anti-sliding layer. The friction coefficient and texture depth of anti-sliding layer were taken as the quantitative index. The icy layer thickness, macadam particle size and macadam temperature were taken as influencing factors, and the full-scale test including three factors was carried out. The BPN (British pendulum number) was measured using British pendulum test, and the status of macadam spalling was observed at the same time. The TD (texture depth) was measured by handle sand patch, the significant analysis, multiple comparison and regression analysis were used to analyze the experimental data. Experimental phenomenon and data analysis show that the three experiment factors have remarkable effect on the design indexes, and there are also prominent interactions among them; the application result of hot melt macadam anti-sliding layer is optimum when icy layer is 2cm. At last 9.5mm particle size of macadam and 90°C temperature of macadam were recommend to use when the thickness of icy layer is 1cm∼3cm.
