Mechanical Behavior of Concrete Pavement considering Void beneath Slabs and Joints LTE

Table 2

The location of the stress under different conditions.

Void size (m)	Joint stiffness
	10 q	q	0.1 q	0.01 q
0.3	0.782	0.85	0.93	0.965
0.6	0.775	0.84	1.212	1.551
0.9	0.768	0.826	1.705	2.61
1.2	0.759	0.81	1.739	3.499

The maximum stress occurs at the top of loaded slab.
