高速公路沥青路面车辙与路面使用性能影响分析

通过对王楼至兰考高速公路长期的观测与调查,研究了车辙病害的发展情况、外部环境因素及其对路面使用性能的影响。研究结果表明：河南地区高速公路沥青路面车辙病害与气温、交通荷载、降雨量等外部环境关系显著,高温以及重载车辆的反复荷载作用是造成车辙的主要原因;河南地区高速公路典型病害的发展可直接反应在路面平整度的变化中,车辙与平整度存在线性相关关系,可通过修复车辙来保证路面良好的平整度。

Analysis of Ruts on Asphalt Pavement and Their Impact on Pavement Performance

The development of rut disease and its external causes and impact on pavement performance were studied in terms of long-term observation and investigation on Wanglou-Lankao Expressway. The results show that in Henan Province, rut diseases are mainly caused by high temperature and repeated load from heavily loaded vehicles; there＇s a linear relationship between ruts and evenness, so the evenness of asphalt pavement could be guaranteed by repairing ruts.
