浅议路基路面回弹弯沉检测中存在的问题

摘要

从回弹弯沉的定义和重要性出发,阐述现行路基路面设计、施工及检测规范中各类弯沉的概念、区别和联系,对规范中弯沉现场测试标准车参数、路面弯沉检测过程中温度测试频率、温度修正方法、弯沉特异值标准及舍弃原则提出合理化建议,对影响路基、路面弯沉季节影响系数的相关因素进行分析,指出目前设计和检测中存在的问题,并建议各省、市或自治区根据其实际情况建立各自的路基、路面弯沉季节影响系数地方性标准,以规范检测工作.%Based on the definition and importance of rebound deflection,this paper explained the concept, distinction and connection of various tyPes of deflection in the existing subgrade/pavement design, construction and inspection. This paper put forward some suggestions on parameters of the standard vehicle for site rebound test for onsite rebound test and rationalizing the temperature test frequency, temperature correction method,the specific value of the deflection and the abandonment principle in pavement rebound site test. This paper analyzed relevant factors influencing the subgrade/pavement deflection season influence coefficient,and pointed out problems existed in current design and testing, and suggested that the provinces, municipalities or autonomous regions may establish their own roadbed, road deflection season influence coefficient standards to standardize the testing work.
