Guidelines for the Design of Flexible Pavements (Fourth Revision) (without the CD) 2019 الطبعة
IRC 37:2019 delivers detailed instructions for designing flexible pavements tailored to India's conditions, emphasizing both structural integrity and functionality throughout the pavement's lifespan. It includes methodologies for traffic evaluation, layer composition, material characteristics, and fatigue damage evaluation, with additional focus on frost-prone regions. This code is crucial for engineers and planners aiming to create cost-effective and long-lasting flexible pavement systems under diverse traffic and environmental influences.
