Pavement Design

IRC 15 is the CONSTRUCTION code for concrete roads — IRC 58 designs the pavement, IRC 15 tells you how to BUILD it. Covers PQC laying (slip-form is standard for…

IRC SP:16 defines how smooth a road must be — using IRI (International Roughness Index) as the primary measure. New NH bituminous surface must achieve IRI ≤2.5 …

This IRC code is crucial for engineers involved in the construction of low-volume roads and rural access roads where WBM technology is a viable option. It detai…

IRC 37 is India's primary code for flexible (bituminous) pavement design — used for every national and state highway project. The 2018 edition adopts a mechanis…

This IRC code outlines the methodology for designing cement concrete mixes for pavements, focusing on achieving specific strength and durability requirements. I…

IRC SP:46 covers fibre reinforced concrete (FRC) for pavements — adding steel or synthetic fibres to PQC improves crack resistance, reduces slab thickness by 15…

This IRC code is essential for engineers involved in concrete pavement construction and maintenance. It details the crucial practice of joint sealing, which aim…

IRC 58 is India's primary code for rigid (cement concrete) pavement design — the counterpart of IRC 37 for flexible pavements. Uses fatigue and erosion criteria…

This IRC code provides a comprehensive framework for designing and constructing cement concrete pavements on rural roads. It emphasizes appropriate material sel…

IRC SP:62 adapts IRC 58 (rigid pavement design) for low-volume rural roads. Thinner slabs (150-200mm), lower concrete grade (M30), and simpler construction (no …

This IRC code details the construction of Roller Compacted Concrete (RCC) pavements, a high-strength, economical pavement type suitable for heavy-duty applicati…

This IRC code is essential for engineers involved in road construction, offering a framework for incorporating cement-treated and recycled materials into paveme…

CRCP eliminates transverse joints (the weakest point of conventional concrete pavement) by using continuous longitudinal reinforcement (0.6-0.7%) that holds tig…

IRC SP:72 is the rural road version of IRC 37 — flexible pavement design for traffic <2 MSA. Uses a simplified CBR-based catalogue approach (no mechanistic anal…

This IRC code outlines the principles and practices for designing and constructing Roller Compacted Concrete (RCC) pavements. It details the selection and propo…

The IRC Guidelines for Conventional and Thin White-Topping focus on ensuring the durability and performance of concrete pavement overlays. It details essential …

This IRC code outlines the established procedures for employing the Benkelman Beam Deflection Technique to evaluate the structural adequacy of flexible pavement…

This IRC code serves as a vital resource for engineers involved in the lifecycle management of rigid pavements. It details systematic approaches to identify and…
