What is Seasonal Heave in Expansive Clays about?
This paper discusses the challenges of constructing road pavements on expansive clay subgrades, highlighting the seasonal movements of the soil due to moisture changes. It presents a seasonal heave prediction method for Australia and reviews techniques such as lime stabilization, prewetting, and drainage to mitigate these issues. The authors emphasize the importance of appropriate site drainage and the construction of pavements on initially wet subgrades to reduce damage and maintenance costs.
