Tube Suction Test for Evaluating Durability of Cementitiously Stabilized Soils
The demand for pavement networks in the United States is greater than ever, and the conditions of existing roadways are worsening due to heavier vehicles and increased volume. According to the recent report by AASHTO/TRIP, only half of the nations major roads are in good condition (AASHTO, 2009). This report found that major urban centers have the roughest roads some with more than 60% of roads in poor condition. Weak subgrade soils are a leading factor in this regard. In the last few decades, pavement engineers have been challenged to build, repair and maintain pavement systems with enhanced longevity and reduced costs. Specifically, efforts have been made to improve the design methodology (AASHTO, 2004) and to establish techniques for modification of highway pavement materials. Cementitious stabilization is one of these techniques; it enhances the engineering properties of subgrade soils, which is essential for structurally sound pavements.
