石灰岩沥青路面铺装层抗滑耐磨性能研究

Study on the anti-skid and abrasion resistance of the anti-skid pavement of limestone asphalt pavement

结合施工案例,开展室内和室外试验对石灰岩沥青路面抗滑铺装层的抗滑耐磨性能进行研究。通过原材料试验和配合比设计,合理确定矿料级配和最佳油石比。通过试验对比分析石灰岩和玄武岩沥青混合料的抗滑性能,得出二者的衰减规律。分析施工现场沥青路面构造深度和摆值的检测结果,得出石灰岩沥青路面铺筑层可满足路面抗滑要求。

Combined with construction cases,indoor and outdoor tests were carried out to study the anti-skid and wear-resistant performance of limestone asphalt pavement anti-skid pavement.Through raw material testing and mix ratio design,the gradation of mineral materials and the best oil-stone ratio are reasonably determined.The anti-skid performance of limestone and basalt asphalt mixtures are compared and analyzed through experiments,and the attenuation law of the two is obtained.Analyzing the test results of the construction depth and swing value of the asphalt pavement at the construction site,it is concluded that the limestone asphalt pavement paving layer can meet the anti-skid requirements of the pavement.
