TENSILE PROPERTIES OF SUBBASES FOR USE IN RIGID PAVEMENT DESIGN

THIS REPORT SUMMARIZES THE FINDINGS OF PROJECT 3-8-66-98, "EVALUATION OF TENSILE PROPERTIES OF SUBBASES FOR USE IN NEW RIGID PAVEMENT DESIGN," AND DESCRIBES A SERIES OF RESEARCH ACTIVITIES RELATED TO THE DEVELOPMENT OF A METHODOLOGY FOR EVALUATING THE TENSILE PROPERTIES OF STABILIZED MATERIALS AND A STRUCTURAL DESIGN PROCEDURE FOR STABILIZED PAVEMENT LAYERS. THIS SUMMARY INCLUDES INFORMATION DEVELOPED ON THE TENSILE CHARACTERISTICS OF ASPHALT-TREATED, CEMENT-TREATED, AND LIME-TREATED MATERIALS, INCLUDING THE CORRELATION OF THE INDIRECT TENSILE TEST WITH THE COHESIONMETER, THE UNCONFINED COMPRESSIVE TEST, AND THE HVEEM STABILOMETER. IN ADDITION, THE RESULTS OF A LIMITED SERIES OF FATIGUE TESTS CONDUCTED USING THE INDIRECT TENSILE TEST ARE SUMMARIZED. THE STABILIZED LAYER DESIGN PROCEDURE DEVELOPED BY THE PROJECT AND REPORTED IN RESEARCH REPORT 98-13 IS DISCUSSED AND SUMMARIED. FINALLY, THIS REPORT PROVIDES A SUMMARY OF THE FINDINGS AND RECOMMENDATIONS WHICH HAVE EMANATED FROM THIS PROJECT AND PROVIDES A SYNTHESIS OF IMPLEMENTATION INDEAS FOR PUTTING THE FINDINGS OF THE PROJECT INTO PRACTICE. THESE INCLUDE ASPECTS WHICH HAVE ALREADY BEEN PUT TO USE AS WELL AS THOSE WHICH ARE PROJECTED FOR THE FUTURE. /NTIS/
