摘要
为研究沥青路面抗滑性能衰减规律,依据实际道路交通量参数进行室内模拟并检测路面抗滑性能变化情况。首先,室内成型与北京市怀柔区杨雁路路面类型和技术指标相同的沥青混合料试件;其次,结合实际交通量参数利用MMLS3小型加速加载设备进行交通荷载模拟;最后,在不同测试周期下测试其抗滑性能。结果表明,在长期车辆荷载作用下路面抗滑性能先上升后下降,在服役一定时间后路面抗滑性能衰减趋于平缓,选用粗级配沥青混合料和高品质集料能提供较好的路面宏微观纹理,可有效改善路面抗滑性能。
In order to study the attenuation law, indoor simulations are carried out based on actual road traffic parameters and the changes in the pavement’s anti-skidding performance are detected. Firstly, the asphalt mixture specimens with the same pavement type and technical indicators as Yangyan Road in Huairou District, Beijing is indoor molded;Secondly, combing with actual traffic volume parameters, traffic load is simulated by MMLS3 small acceleration loading equipment;Finally, anti-skidding performance under different test cycles are tested. The results show that under long-term vehicle load, the pavement’s anti-skidding performance firstly rises and then decreases.After a certain period of service, the pavement’s anti-skid performance decays gradually. The choice of coarse-graded asphalt mixture and high-quality aggregates can provide better pavement macros texture and effectively improve the anti-skid performance of the road surface.
