Research on the Intelligent Detection Technology of the Compaction Quality of Asphalt Concrete Pavement
Compaction quality control is a key link of road construction,directly affecting the performance and life cycle of the road.In order to solve the engineering technical pain points of poor sampling representativeness,lagging quality assessment,large error and low efficiency of manual detection means,and avoid the risk of construction collision of heavy machinery in the compaction process,this paper is based on the vibration spectrum analysis method to build a calculation model to estimate the compaction degree using vibration acceleration.By linking the field compaction quality test results,the standard compaction spectrum is established,and the rapid and dynamic monitoring system of the core quality control indexes such as compaction degree and compaction temperature is realized.The roller collision warning system module is developed,which integrates the functions of regional detection,acoustic and optical alarm,braking and monitoring feedback.The site test application shows that the system has stable working efficiency,complete detection coverage,strong representativeness of feedback indexes,and high construction safety.
