The IITPAVE software has a wide range of applications in pavement design and analysis, including:
. It models the pavement as a system of multiple layers—typically including the bituminous surface, base, sub-base, and subgrade—each defined by its thickness, elastic modulus ( ), and Poisson's ratio (
IITPAVE is a specialized structural analysis utility engineered to model under standard vehicular loads. Rather than relying strictly on empirical charts, it applies mechanistic principles to evaluate how road sections handle stress.
The software models the pavement as a multi-layer elastic system. The bottom-most layer (the subgrade) is considered semi-infinite, while all upper layers are assumed to be infinite in the horizontal extent and finite in thickness. IITPAVE then calculates critical pavement responses, such as stresses, strains, and deflections, under a given wheel load. The key outputs that are of interest are:
