Modern Soil Stabilization Techniques
Soil stabilization techniques are necessary to assure adequate subgrade stability, especially for weaker or wetter soils. It is widely recognized that the selection between the cementitious stabilizing agents cement and lime is based on the Plasticity Index (PI) of the primary soil type being improved. A PI of 10 is considered by many as the threshold that justifies the cost for use of Portland cement compared with lime. The use of bituminous stabilizing agents is somewhat less common, but worthy of consideration. Foamed bitumen is a developing technology that shows excellent performance. In the comparison of cement versus bitumen for stabilization, similar advantages and disadvantages as Portland Cement Concrete (PCC) versus Hot Mix Asphalt (HMA) pavements are recognized. Cement stabilization offers worldwide availability and ease of application. Bituminous stabilization provides material flexibility and resistance to cracking. Depending on regional availability, cost for construction is variable.
