摘要
路面平整度是决定行车舒适性的重要因素之一,由于西藏特殊的气候条件,路面平整度控制一直是沥青路面铺筑的一大难题。以G6京藏高速公路那曲至羊八井段为例,提出西藏高原地区沥青路面初始平整度的控制措施。在改进施工工法的基础上,引入车载式高精度激光断面仪快速检测技术,对施工过程中及工后平整度进行检测评价。总结归纳了工程施工中取得的相关技术成果,以期为西藏沥青路面平整度控制提供实践经验参考。
Road smoothness is one of the important factors that determine driving comfort.Due to the special climate conditions in Tibet,road smoothness control has always been a major problem in asphalt pavement paving in plateau areas.Taking the first expressway in Tibet,the newly built project between Naqu and Yangbajing section of G6 Beijing-Tibet Expressway as an example,the smoothness control measures of asphalt pavement in high altitude areas have been proposed.Being based on the improved construction method,the vehicle-mounted high-precision laser profiler rapid detection technology has been introduced to detect and evaluate the flatness during and after construction.The related technical achievements obtained in the project have been summed up in order to provide a reference for the smoothness control of asphalt pavement in Tibet.
