| Anti-sliding performance of road is very important for traffic safety, especially ice roads in rainy winter must have good anti-sliding performance. Humid mountain areas in Southern China, many "sleet" disasters in winter,and because air is humid, the temperature low, this tends to produce thin ice and the dark ice at roads. The temperature around 0℃, the ice on the road surface is a long-time in the wet state, condensate water film makes the ice surface loss of surface friction completely, so that the road capacity to a substantial decline in anti-slide, significantly reduce motor vehicle driveability and driving safety, prone to traffic accidents, serious only closed to traffic, disrupting the normal life of the masses of people the state. Need to find effective ways to prevent Lumianjiebing, in the case of thin ice, can take advantage of the construction of the road itself, so that vehicles in the process, to automatically break the ice to maintain a good anti-sliding performance of the road. In this paper, rough road as the research object model, through experiments on the rough-type road in freezing , comparative analyzes the result of ice-breaking effect and anti-sliding performance.Firstly analyzes the road surface friction and anti-slide mechanism in this article, structure of different texture depths and different air void of the mixture were made by comparative analysis of ice sliding, obtained under certain precipitation can keep a good anti-sliding effect of the texture depth range of road surfaces constructed , and then determine the road surface drainage can ensure timely mixture target air void. Air void and texture depths as targets for the indicators of the rough-type road surface mix design .The test results for their conventional pavement performance to meet requirements, particularly still has a good anti-sliding effect after the road are freezing. Proved that the rough-type road has a good anti-sliding performance under the conditions in the little and thin ice .
