Monitoring and performance evaluation of a road reconstruction project with lime stabilized fine-grained subgrade

The use of lime as a soil stabilizer is well documented in the literature. From a historical view point, the first project in modern times which used lime was built in 1948 at Fort Sam Houston in Texas. Army roadways had failed and needed to be reconstructed within a limited budget. Lime was used as a cost effective measure and mixed with the existing roadways. The Army constructed the two block section of roadway while the Texas Highway Department conducted the initial laboratory tests (National Lime Association, 1977). Because of the success of the initial project, both the Army and Texas Highway Department have used lime for soil stabilization.
