is the definitive computation tool for structural design and mechanical analysis of flexible pavements in India, developed by the Indian Institute of Technology Kharagpur (IITKGP) under the Ministry of Road Transport and Highways (MoRTH) Research Scheme R-56. It serves as the official software engine mandated by the Indian Roads Congress (IRC) guidelines—specifically IRC:37 —to perform mechanistic-empirical design checks by evaluating structural stresses, strains, and deflections under vehicle wheel loads.

IITPAVE is more than just a program; it is a mechanistic-empirical (M-E) software solution tailor-made for Indian conditions. It is the updated version of the earlier FPAVE program, developed under the Ministry of Road Transport and Highways (MoRTH) Research Scheme R-56, “Analytical design of Flexible Pavement”. The software allows engineers to move beyond outdated empirical methods and adopt a performance-based design approach that aligns with the latest guidelines of the Indian Roads Congress (IRC).

Utilizing IITPAVE provides several advantages for engineers: is the definitive computation tool for structural design

Using the design traffic (in terms of cumulative million standard axles, CMSA), find the permissible strain values from the performance equations provided in IRC:37-2018 or as per your project criteria. IITPAVE will output the computed strains. Compare: It is the updated version of the earlier
