Paper Title:
Microscopic Mechanism Analysis and Experimental Study of Void Beneath Slab
  Abstract

The main cause of cement concrete pavement fracture is void beneath slab, while water is an important factor of void beneath slab. In order to clearly understand impact of water on void beneath cement concrete pavement, this paper analyzes penetration soaking role and scouring of water and studies the evolution process of void under slab. It is founded that the erosion of the grassroots and void beneath the plate influence each other. Conducting a Small-size simulation test by using Falling Weight Deflectometer (FWD), the movement condition of the water in empty area under concrete road and the effect of void size on current scour are got under the action of moving load.
