摘要
基于沥青路面抗滑耐久性研究进展,归纳了沥青路面抗滑耐久性影响因素,对比了室内加速磨光试验机,并分析总结了常见的抗滑性衰变模型.结果表明,沥青路面抗滑耐久性受材料、荷载和环境共同影响,室内加速磨光能在一定程度上模拟现场沥青路面磨耗磨光现象;长期抗滑预估模型趋向于由单一因素向多因素发展,模型参数选择应立足于实际,并平衡好难度和精度要求.
Abstract
Based on the progress in the research on skid resistance durability of asphalt pavement,the influencing factors of skid resistance durability of asphalt pavement are summarized,the existing indoor accelerated polishing test machines are reviewed,and the common skid resistance attenuation models are analyzed and concluded.The results show that the skid resistance durability of asphalt pavement is affected by materials,load and environment,indoor accelerated polishing can simulate the in-situ abrasion and polishing of the asphalt pavement to a certain extent,the long-term skid resistance prediction model tends to develop from a single factor to multiple factors.The selection of model parameters should be based on reality and balance the difficulty and accuracy requirements.
