AN EVALUATION OF METHODOLOGY FOR PREDICTION AND MINIMIZATION OF DETRIMENTAL VOLUME CHANGE OF EXPANSIVE SOILS IN HIGHWAY SUBGRADES: VOLUME I--RESEARCH REPORT
This report concludes a 4-1/2-year study involving an evaluation of methodology for prediction and minimization of detrimental volume change of expansive soils in highway subgrades. The purpose of the study was to evaluate and make recommendations concerning the major aspects of expansive soil in highway subgrade problems: namely, describe (on the basis of physiographic areas) the occurrence and distribution of expansive soils, define and verify the roles of the microscale mechanisms that cause volume change, evaluate expedient methodology for identification and classification of potentially expansive soils, evaluate methodology for testing and prediction of anticipated volume change, evaluate and recommend appropriate treatment alternatives for new and existing highways, and recommend practical procedures for design and construction of new pavements and maintenance of existing pavements. /FHWA/
