![]() ![]() The studied soil types involved Fine grained silt (ML), poorly graded sand (SP), soft sand, Sandy-Clay (CH), Salty sand, clay and soft clay. Ten recent studies that have used different stabilizing mechanisms for stabilizing the strength capacity of different subgrade soils used as pavement foundations. The current research aims to review some relative efficiency of several mechanical and chemical stabilizing mechanisms that have been currently examined by several researchers independently. Hence, it is quite agreed that there is a necessity for evaluating and assessing the comparative performance of these pavement subgrade stabilizing methods and treatments. Some of these techniques and materials are becoming more common due to their comparative cost-effectiveness, practicality and efficiency. ![]() There are a variety of techniques and materials that have been lately developed and employed for stabilizing weak subgrade soils in pavement construction. ![]()
