The depth and thickness of concrete pavement is the same.
As cross-section of concrete pavement is Double trapezoidal. So thickness or depth at the interior of concrete pavement is equal to 0. 85 thickness or depth at sides of concrete pavement.
Depth/thickness of concrete pavement is given by (3W/flexural stress). Where W = wheel load.

depth of concrete = d = √(3w/stress),
d= √(3*6300/21)=30,
Now,
Thickness of Concrete= 0.85*d,
t=0.85*30,
t=25.5cm.
d= √(3*6300/21)=30,
Now,
Thickness of Concrete= 0.85*d,
t=0.85*30,
t=25.5cm.

depth of concrete=d= sqrt(3w/stress),
d=sqrt(3*6300/21)=30,
Now,
Thickness of Concrete= 0.85*d,
t=0.85*30,
t=25.5cm.
d=sqrt(3*6300/21)=30,
Now,
Thickness of Concrete= 0.85*d,
t=0.85*30,
t=25.5cm.

Wheel load 3600.
Stress 21
√3 * 3600/21=√300=30
Now
.85* d= .85 * 30 = 25.5cm.
Stress 21
√3 * 3600/21=√300=30
Now
.85* d= .85 * 30 = 25.5cm.

What is the difference between the depth of concrete and thickness of concrete @Quasim.

Using Goldbeck equation:
t = (3W÷stress)^0.5.
t interior = 0.85t.
t = (3W÷stress)^0.5.
t interior = 0.85t.

Stress = load/area,
Thickness at interior is 0.85 d.
Thickness at interior is 0.85 d.

d = (3W/stress)^0.5,
= (3 * 6300/21)^0.5,
= 30.
= (3 * 6300/21)^0.5,
= 30.
