Strength Evaluation on Stabilized Sub Grade of MMGSY Road

Abstract

Abstract Village and Other districts’ roads play an important role to establish a link between the private and the commercial sector and it is beneficial for the financial growth of a nation. Govt. intended to upgrade and new construct the Village Road (VR) & Other District Road (ODR) road through Pradhan Mantri Gram Sadak Yojana (PMGSY) & Mukhya Mantri Gram Sadak Yojana (MMGSY) since 2000 therefore Structural Analysis is essential for upgrading the existing pavement performance. Conventional practice is based on the lab. outcomes but due to seasonal various required field evolution for getting correct periodic data for up gradation as well as construction of non plan road. Various techniques are available for structural evaluation of pavement. DCP (Dynamic Cone Penetration) test is a well-known practice to evaluate the strength of subsoil on the field. The DCP test is the simplest apparatus designed by Transportation Research laboratory (TRL), UK for on-field strength assessment. Presence research carries out a laboratory and field investigation on the subgrade of MMGSY road of central Gujarat, India, and also focuses on the enhancement of strength of subgrade utilization of nano materials. The relationship of DCP penetration in mm/blow with Field The California Bearing Ratio (CBR) & CBR with resilient modulus of sub grade soil (Mrs) was also established at MMGSY road for structure performance evaluation of the pavement.
