Evaluation of Conventional and Sustainable Modifiers to Improve the Stiffness Behavior of Weak Sub-Grade Soil

The paper focuses on the improvement of clayey soil (A-6) with locally available and cheap modifiers, in terms stiffness behavior weak subgrade for flexible pavement. modifiers used include lime (hydrated), marble waste sand. specimens underwent triaxial testing Clegg impact testing. Triaxial involved assessment resilient modulus (MR) using Impact Hammer. According to study, proved be most influencing modifier as it improves better than other modifiers. A quite accurate statistical relationship between MR variables (including Impact) procedure has been established
