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

Table 3

The location of the stress under different conditions.

Void size (m)	Joint stiffness
	10q	q	0.1q	0.01q
0.3	0.761	0.84	0.927	0.957
0.6	0.732	0.878	1.301	1.558
0.9	1.363	1.52	2.056	2.716

The maximum stress occurs at the top of loaded slab.
