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

Table 5

The location of the stress under different conditions.

Void size (m)	Joint stiffness	Base course modulus (MPa)
		2000	4000	6000	8000	10000
0.3	q	0.825	0.802	0.781	0.761	0.744
	0.01q	0.922	0.906	0.886	0.864	0.844
0.6	q	0.815	0.793	0.772	0.753	0.736
	0.01q	1.299	1.302	1.315	1.325	1.34
0.9	q	0.8	0.78	0.76	0.741	0.724
	0.01q	2.012	2.115	2.184	2.232	2.269
1.2	q	0.778	0.763	0.744	0.727	0.71
	0.01q	2.518	2.745	2.881	2.976	3.046

The maximum stress occurs at the top of loaded slab.
