  • The frictional coefficients of several parts for cement concrete runway in an airport were tested by an anti-slide-test truck of T10 type.Different textural features were analyzed by photo analysis method and characteristic description method.The influence law of pavement superficial texture on frictional coefficient was discussed based on test results.A model of pavement anti-slide capacity was proposed based on texture characteristic parameters.According to the analysis of macro, rough and micro texture characteristic parameters, a pavement anti-slide frictional coefficient model was proposed based on texture characteristic.Analysis result shows that frictional coefficients vary from 0.40 to 0.42 when constructional depths are 0.6-0.7 cm on the similar texture characteristic roads.For the significant different texture characteristics, frictional coefficients are 0.43, 0.75 when constructional depths are 0.70, 0.78 cm respectively, so the influence of texture characteristic on pavement frictional coefficient can not be neglected.Based on the analysis of pavement texture characteristic parameters, the anti-slide model can be used to analyze the anti-slide capacity of old runway pavement quantitatively.
