• Abstract:
  A field and laboratory study was begun in 1995 to evaluate the engineering behavior of a stabilized soil from two test sections beneath a reconstructed roadway. This roadway is designated FM 1343 and is located in Medina County, south of SH 90, approximately 20 miles west of San Antonio, Texas. One test section was stabilized using Portland cement, and the other with lime. The primary intent of the research project was to make a comparison between the two stabilization methods in terms of their long-term effectiveness in controlling moisture susceptibility of pavement subgrade soils. Soil samples were obtained from both test sites. For the comparison, similar tests were performed on the soil samples obtained from each site. Initial testing indicated that both stabilization methods are comparable in plasticity reduction, strength increase and durability. Instrumentation necessary for long-term monitoring was installed at both test sites, and initial data collected. It is expected that Texas Department of Transportation (TxDOT) personnel will continue this data collection over the next 5 years. Appropriate conclusions regarding the effectiveness of lime versus cement will be drawn at the end of the 5-year monitoring period after the data collected has been reviewed.
