ESTIMATIONS ON INDIRECT TENSILE STRENGTHS FOR LIME-TREATED MATERIALS

WITHIN THE FRAMEWORK OF A RESEARCH EFFORT CONCERNED WITH THE EVALUATION OF TENSILE PROPERTIES OF STABILIZED SUBBASE MATERIALS, IT WAS DESIRED TO ESTABLISH A MEANS TO PREDICT INDIRECT TENSILE STRENGTH FROM TEXAS HIGHWAY DEPARTMENT TESTS FOR LIME-TREATED MATERIALS. EXPERIMENTS WERE DESIGNED TO DEVELOP A PREDICTIVE EQUATION IN TERMS OF FACTORS INVOLVED WITH MIX DESIGN, CONSTRUCTION, AND CURING AND TO DETERMINE WHETHER ACCEPTABLE CORRELATIONS EXIST BETWEEN THE INDIRECT TENSILE TEST AND BOTH THE COHESIOMETER TEST AND THE UNCONFINED COMPRESSION TEST. THESE CORRELATIONS WERE DEVELOPED BY USING 2 APPROACHES: THE FIRST VARIED 5 FACTORS (COMPACTIVE EFFORT, MOLDING WATER CONTENT, LIME CONTENT, CURING TEMPERATURE, AND CLAY CONTENT) AT 3 LEVELS EACH, AND THE SECOND, BASED ON TEXAS HIGHWAY DEPARTMENT TESTING PROCEDURES, VARIED ONLY MOLDING WATER CONTENT, LIME CONTENT, AND CLAY CONTENT BECAUSE CURING TEMPERATURE AND COMPACTIVE EFFORT ARE FIXED BY THE TEST SPECIFICATIONS. IT WAS FOUND THAT ACCEPTABLE CORRELATIONS FOR LIME-TREATED MATERIALS EXIST FOR BOTH APPROACHES BETWEEN THE INDIRECT TENSILE TEST AND COHESIOMETER TEST, THE INDIRECT TENSILE TEST AND UNCONFINED COMPRESSION TEST, AND THE INDIRECT TENSILE TEST AND THE COMBINED RESULTS OF THE COHESIOMETER AND UNCONFINED COMPRESSIVE TEST. THESE CORRELATIONS PROVIDE THE CAPABILITY OF ESTIMATING THE INDIRECT TENSILE STRENGTH FROM THE COHESIOMETER OR THE UNCONFINED COMPRESSION TEST DATA OR BOTH FOR LIME-TREATED MATERIALS USED IN PAVEMENTS NOW IN SERVICE. /AUTHOR/
