A Study of Cost Comparison of Flexible Pavement Using Different Soils

Abstract

India is home to the world’s second-largest road network. It has a diverse range of soil types, each with its own set of conditions and characteristics, on which the road network is built. IRC: 37-2018 was used for the Design and Cost Analysis of Flexible Pavement for five distinct types of soils: Black cotton soil, Alluvial soil, Sandy soil, Red Laterite soil, and Murram soil. The Resilient modulus which depends on CBR value of the soil has been found to influence the pavement thickness, strength and performance. The project’s cost is determined by the pavement thickness, which again is determined by the soil’s CBR value. By employing a soil with a high CBR value, the project’s pavement thickness and cost will be decreased. On poor or problematic soils, soil stabilisation techniques should be employed to improve CBR value and save project expenses. According to the findings, employing the CBR value improves the pavement’s strength and hence saves time when planning a pavement.
