Exact value of contact pressure normally assumed in pavement design is:
5 kg/cm²
6 kg/cm²
7 kg/cm²
9.5 kg/cm²
If tyre is under-inflated, the relation between contact pressure (CP) and tyre pressure (TP) is:
CP = TP
CP < TP
CP > TP
CP = 0
Rigidity factor of tyre is defined as the ratio of:
Tyre pressure / Contact pressure
Wheel load / Tyre pressure
Contact pressure / Tyre pressure
Wheel load / Contact area
Equivalent Single Wheel Load (ESWL) is defined based on equality of:
Contact pressure
Vertical stress or deflection
Tyre pressure
Wheel spacing
At depth z = d/2, ESWL for a dual wheel assembly is equal to:
P
2P
P/2
4P
Equivalent Axle Load Factor (EALF) is proportional to:
(P1/P2)2
(P1/P2)3
(P1/P2)4
(P1/P2)5
