In order to quantitatively characterize the skid resistance performance of asphalt pavement in ice and snow weather; icy pavement; snow-covered pavement and snow-melting pavement were simulated in the climate laboratory. Pendulum friction tester and T2GO friction tester were used to obtain British pendulum number（BPN）and friction coefficient separately; and the Vaisala mobile detector was applied to detect the thickness of ice layer; snow layer and water film. For various pavement surface condition; the prediction methods of friction coefficient were proposed based on the main factors which causing the attenuation of skid resistance. The results show that the skid resistance performance of icy pavement is mainly affected by the ice layer thickness. The skid resistance performance of snow-covered pavement is affected by the interlayer sliding within the snow layer. During the snow-melting process; a thin ice layer; formed on the snow layer surface; causes a significant decrease in the skid resistance performance of the road surface. The BPN of icy pavement has a good linear relationship with friction coefficient. © 2024 Tongji University. All rights reserved;
