基于便携测温测厚仪的沥青摊铺质量可视化实时管理

为避免公路沥青路面施工过程中施工温度和摊铺厚度数据记录的人为因素干扰,研制了用于沥青摊铺厚度、施工温度测量和同步定位的便携式测温测厚仪。为实现沥青摊铺质量可视化实时管理,构建了公路施工三维可视化模型,提出了监测信息三维网络可视化集成模型,并基于该便携式装置开发了网络环境下公路路面沥青摊铺厚度温度可视化实时管理系统。应用该系统对天津某高速公路沥青摊铺进行监控,除极少数测点的摊铺厚度和初压温度之外,摊铺温度和终压温度合格率均达到100%。工程应用表明,路面沥青摊铺厚度和施工温度得到良好控制,该系统有助于提高沥青路面摊铺质量管理的效率与水平。

Real-time visual management of the asphalt pavement quality basing on a portable temperature and lift-thickness measuring device

In order to avoid the influence of human behaviors in the data records of construction temperature and lift thickness, a portable detecting device has been developed with the functions of construction temperature measuring, lift thickness measuring, and simultaneous positioning. In the meantime, for the implementation of real-time visual management of the asphalt pavement quality, a three-dimensional highway construction model and a visual integration model of monitoring information were built, and then under the network environment, a real-time visualization system for the quality management of asphalt pavement was developed based on the portable detecting device. This system was applied in a highway project with asphalts pavement in Tianjin, and the qualified rates of the most measurements, except lift thickness and initial compacting temperature in several points, were up to 100%. The results indicate that the asphalt pavement temperatures and the lift-thickness of project were under good control. This system can improve the management efficiency of asphalts pavement quality, and provide a new technical approach for the quality control of road construction.
