Recent research has shown that the subgrade soil type and its engineering properties govern the performance of the pavement, especially for clayey soils. However, current application of the Pavement_ME in Indiana does not fully account for the changes of type of soil and stiffness that may arise with treatment. This research addresses this issue by exploring engineering properties, namely fines content, plasticity index, unconfined compression strength and resilient modulus of subgrade stabilization alternatives. The effects of changes in moisture content and temperature on the stiffness of treated subgrades are also studied. Three A-7-6 soils and one A-6 soil mixed with …
