Embodiment Construction
[0016] Such as figure 1 As shown, the present invention mainly adopts a double-rear-axle eight-wheel truck as a deflection detection vehicle to detect the rebound deflection of different subgrade deflection measurement points, and further calculate the rebound modulus of different measurement points of the subgrade respectively to obtain different measurement points. The arithmetic mean value of the point rebound modulus is used as the rebound modulus of the subgrade.
[0017] Combined with the roadbed entity project, explain the method of the present invention: use a Foton truck or an Iveco Hongyan double rear axle truck, check that the inflation pressure of each tire of the double rear axle truck is 1.20±0.05MPa; add goods to the double rear axle truck slot, Ensure that the axle load of the double rear axle is 200±1kN; adjust the relative position of the goods to ensure that the difference between the rear axle and the rear front axle load is less than 2kN; respectively plac...
