Roadbed quality control method based on dynamic resilience modulus correction

Abstract

The invention provides a roadbed quality control method based on dynamic resilience modulus correction, relates to the field of road engineering, and solves the technical problem that in the prior art, deflection value calculation is disjointed with actual working conditions on site, and roadbed construction quality misjudgment is easily caused. The method comprises the following steps: measuring a first dynamic resilience modulus of a roadbed base and a second dynamic resilience modulus of roadbed filler under different compaction degrees; calculating the difference between the actual moisture content of each layer of roadbed and the optimal moisture content of the corresponding roadbed filler, and calculating the actual dynamic resilience modulus of each layer of roadbed filler; converting the thickness of each layer of roadbed into the total equivalent thickness of the roadbed consistent with the actual dynamic resilience modulus of the topmost filler on the top surface of the roadbed; and based on the first dynamic rebound modulus, the total equivalent thickness of the roadbed and the actual dynamic rebound modulus of the topmost filler, determining the acceptance deflection value of the top surface of the roadbed for acceptance judgment of the construction quality of the top surface of the roadbed. The method is used for roadbed construction quality control scenes of traffic civil engineering.
