路面弯沉是路面及路基结构整体强度和刚度的直观反应,是工程整体强度质量的重要检测指标.因此,了解路面湾沉的变化规律,正确测试路面弯沉值,对于正确评价路面质量有着极其重要的意义.%Pavement deflection is the intuitive response of the strength and stiffness of pavement and roadbed structure and the important index to test the strength quality of the whole project. Therefore, it is very important for correct evaluation of pavement quality to understand the variation of road bay sink and test the pavement deflection values correctly.
