Since the loads causing failure of pavements are mostly applied by single, tandem,
tridem and other multiple axles, stresses should be determined for the conditions illustrated
in figs. 3 to 6. The IITRIGID software used in IRC:58-2002 for the computation of flexural
stress in the edge region due to single and tandem axle loads was based on Picket and
Ray (1951)’s work on computation of stresses in infinite slabs. The software is still valid for
computation of load stress in the edge region of pavements without any concrete shoulder
without any temperature gradient. Finite Element Method (FEM) is more appropriate for
stress
computation for a wide variety of load, temperature, geometry and boundary conditions.
Finite element analysis has been carried out using IITSLAB-II, a software developed at IIT
Kharagpur, to compute flexural stress due to the combined action of load (single, tandem and
tridem axles) and different temperature differentials (positive and negative).
