A Deep Dive into IRC:42-1972 – A Standard for Pavement Construction Materials

‍

The Indian Roads Congress (IRC) Code 42-1972 provides a robust framework for evaluating locally available materials for pavement construction. Designed to optimize cost and ensure quality, the code outlines procedures for testing, documenting, and utilizing materials like aggregates, road stones, and soil-gravel mixtures. It is an essential guide for engineers striving to balance economic efficiency with structural durability in road projects.
