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

Table 4

The stress of loaded slab with different void sizes.

Void size (m)		Joint stiffness
Loaded slab	Unloaded slab	10q	q	0.1q	0.01q
0.3	0.1	0.779	0.851	0.929	0.964
	0.2	0.76	0.84	0.922	0.962
0.6	0.2	0.746	0.812	1.246	1.554
	0.4	0.725	0.802	1.281	1.556
0.9	0.3	0.71	0.837	1.766	2.625
	0.6	0.987	1.093	1.869	2.715
1.2	0.4	0.886	0.957	1.852	3.556
	0.8	1.332	1.353	2.144	3.749

The maximum stress occurs at the top of loaded slab.
