Design of Flexible Pavements by IRC 37:2018

Flexible Pavement Design Simulator

Adjust the sliders below to see how traffic characteristics affect the required thickness of flexible pavement layers. Higher traffic volume, heavier axle loads, and longer design life all increase the stress on the pavement, requiring thicker layers (Surface, Base, Sub-base) to distribute the load and prevent premature failure.

Daily Traffic Volume (Standard Axles/day): 2000 Axles/day

Average Load per Axle (kN): 80 kN

Design Life (Years): 15 Years
