Technical Field

Background
The unit is 0.01mm, and the unit is the total vertical deformation value (total deflection) or the vertical rebound deformation value (rebound deflection) generated at the wheel gap position of a roadbed or a road surface under the load action of a specified standard vehicle. The rebound deflection refers to the deformation of the roadbed or the road surface which can be recovered after unloading after vertical deformation under the action of specified load. The rebound deflection of the road surface not only reflects the integral rigidity and the strength of the roadbed and road surface structure, but also has certain internal relation with the use state of the road surface. Generally, the larger the rebound deflection value is, the larger the plastic deformation of a road surface structure is (the rigidity is poor), and meanwhile, the fatigue resistance is also poor, so that heavy traffic is difficult to bear; on the contrary, the road surface structure has good fatigue resistance and can bear heavy traffic. In addition, the rebound deflection is easy to test, so that the design deflection is adopted as the design index of the overall rigidity of the pavement in the existing asphalt pavement design method in China. And under the action of standard axle load, the road surface rebound deflection value Ls does not exceed the road surface design deflection value Ld meeting the requirements of the road surface use state and the design service life as the design standard, namely Ls is less than or equal to Ld. The method is used as an important weight detection index after completion of the project and reflects the overall strength quality of the pavement. Therefore, the method for correctly testing the deflection of the pavement has an important effect on evaluating the strength of the pavement.
