Abstract: A numerical model calculating displacement of jointed slab on void foundation is established with finite element method. And a method for modulus back analysis of jointed slab is developed based on the theory of system identification. On the ground of above work, this paper has established an iteration method to identify void of rigid pavements using deflection data measured from falling weight deflectometer.

Key words: falling weight deflectometer, system identification, back analysis, joint, void
