Roadbed modulus inversion method for asphalt pavement structure
The invention discloses a roadbed modulus inversion method for an asphalt pavement structure, and relates to the technical field of road engineering. Comprising the steps of obtaining pavement structure data, FWD detection data and an inertia point parameter model, determining a trial calculation range and an initial trial calculation value of the roadbed modulus of the asphalt pavement structure, inputting the pavement structure data into the inertia point parameter model to obtain an inertia point position and a theoretical deflection value, and determining actually measured deflection corresponding to the inertia point position according to the FWD detection data, and by calculating the deflection difference between the theoretical deflection and the actual deflection at the inertia point, when the deflection difference is within a set range, outputting a roadbed inversion modulus value. According to the invention, the effect of accurate inversion of the roadbed modulus can be realized.
