1引言随着干线公路沥青路面管理系统的推广，各地的车载式颠簸累积仪已逐步普及，这就为路面平整度的快速、准确测定提供了物质条件。以往工程验收和养护检查中采用3m直尺抽验法评定路面平整度，效率低、精度差，养护检查中有时甚至采用目测法评定，使路面平整度的重要性没有得 1 Introduction With the promotion of trunk road asphalt pavement management system, vehicle bumpy accumulators around the country have been gradually popularized, which provides a material condition for the rapid and accurate determination of pavement smoothness. In the past project acceptance and maintenance inspection by 3m ruler test method to assess the road surface roughness, low efficiency, poor accuracy, maintenance inspection sometimes even by visual assessment, so that the importance of pavement roughness did not have
