Discussion on Issues Related to Laser Deflection Detection of Asphalt Concrete Pavement
Road surface deflection not only reflects the overall strength and stiffness of the structural layer and soil layer of the road surface,but also has a certain internal connection with the use status of the road surface.As an important testing indicator after the completion of the project,it reflects the overall strength and quality of the road surface.In the practice of new road construction,the deflection value,as an important indicator of pavement structure,needs to be tested before the handover acceptance;In road maintenance operations that have already been put into operation,it is also necessary to investigate and evaluate the condition of the road surface.However,traditional deflection detection methods are time-consuming and labor-intensive,making it difficult to meet the needs of rapid detection.As an emerging detection instrument,the biggest advantage of the laser deflection detector is its ability to quickly detect road surface deflection,and its work efficiency far exceeds traditional detection methods.
