The pavement made by rolling crushed stone according to the principle of embedded and squeezing can also be used as the surface layer or base of the pavement. The structural strength of the crushed stone pavement mainly depends on the interlocking and locking of stone particles and the bonding effect of the grouting material. The force of interlocking and locking depends on the strength, shape, size, surface roughness and rolling quality of the stone material itself. The cohesive force depends on the cohesive force of the filling material and the size of the adhesion between the material and the material. Generally, the initial investment of crushed stone pavement is not high, and it can be improved in stages with the increase of traffic volume. The roughness of the pavement is poor, the dust is easy to be raised, and the rainy days are muddy.
