• Abstract:
  The presence of unstable soils in many areas of Louisiana results in numerous problems in design and construction in these areas. These problem soils are primarily of two categories, the first of which consists of the high clay contents and extreme plasticity that may, or may not, contain significant amounts of organic material. It is with the second category that this study is concerned. These soils are extremely mobile when moisture contents are high and they are frequently found in areas where the moisture content is near or above the liquid limit. Normal practice in this situation has been to either treat the top six or eight inches of this material with lime, or to place a better material above this soil and stabilize with cement. In many cases these approaches have been used in combination. Under some conditions these methods have not been entirely satisfactory, however, since mechanical and economic limitations on the depth of manipulation of the soil have prevented the achievement of sufficient depth of treatment to give the stability desired. ; In order to attempt to find some solution which will alleviate this situation, the Louisiana Department of Highways in cooperation with the United States Department of Commerce, Bureau of Public Roads, has initiated a study of methods of in-place lime treatment and partial stabilization. Several approaches to the problem are being tried.
