Application of Beckman Beam Method for Testing the Rebound Deflection of Roadbed and Pavement in Municipal Roads

路基路面回弹弯沉是反映路基路面整体承载能力的关键性指标,关系到道路的安全性、舒适性和使用寿命,而贝克曼梁法是测试路基路面回弹弯沉的一种快速而有效的路面无损检测技术。分析回弹弯沉检测技术在市政道路施工控制与验收中的应用,探讨温度、湿度、坡度等因素在回弹弯沉检测过程中对弯沉值产生的干扰,通过计算出的修正系数,消除这些因素对实测路表弯沉值的影响,为进一步提高市政道路工程质量检测的准确性和可靠性提供参考。

The rebound deflection of roadbed and pavement is a key indicator reflecting the overall bearing capacity of the roadbed and pavement,which is related to the safety,comfort,and service life of the road.The Beckman beam method is a fast and effective non-destructive testing technology for testing the rebound deflection of roadbed and pavement.The application of rebound deflection detection technology in the control and acceptance of municipal road construction was analyzed,and the interference of factors was explored such as temperature,humidity,and slope on the deflection value during rebound deflection detection.The influence of these factors on the measured road surface deflection value was eliminated through the calculated correction coefficient,providing reference for further improving the accuracy and reliability of municipal road engineering quality detection.
