基于路况云图的沥青路面施工均匀性快速无损检测评价技术
|
摘要
沥青路面的施工不均匀会导致沥青路面早期损害,从而大大缩短其使用寿命。在施工过程中及时发现并采取补救措施尤为重要。文章在分析沥青路面检测技术的基础上,采用激光断面仪、探地雷达快速无损采集沥青路面平均剖面深度、厚度、压实度的点状检测数据,利用点状检测数据绘制路面状况分布云图,评价分析沥青路面施工均匀性。
Asphalt pavement construction uniformity will leads to pavement early damage, thus reduce it's service life. It is important to find the uniformity area in time and take measures. Based on the analysis of asphalt pavement detection technology, the spotted test data of depth, thickness and compaction degree of asphalt pavement were collected by laser cross section and ground penetrating radar. Using the point detection data, the road surface distribution cloud map was drew to evaluate and analyse asphalt pavement construction uniformity.
