SOIL RESILIENCE TEST FOR VIRGINIA FLEXIBLE PAVEMENT DESIGN METHOD

SUBGRADE SOIL STRENGTH IS PRESENTLY DETERMINED BY THE CBR TEST IN VIRGINIA. SINCE SOME SOILS IN THE STATE ARE HIGH IN MICA CONTENT AND ARE RESILIENT, THE PURPOSE OF THIS STUDY WAS TO DETERMINE IF THE EXISTING CBR TEST COULD BE MODIFIED TO MEASURE RESILIENT CHARACTERISTICS. REPEATED CBR AND TRIAXIAL TESTS WERE PERFORMED ON THREE SOILS AT TWO DIFFERENT MOISTURE CONTENTS. THE TEST RESULTS DID NOT CORRELATE. THE AUTHORS ASSUMED THE TRIAXIAL TEST AS REFEREE AND CONCLUDE THAT THE REPEATED CBR TEST IS NOT SUITABLE FOR MEASURING RESILIENCY. THEY RECOMMEND THAT ANY FURTHER WORK BE DIRECTED TOWARD A METHOD RELATING MICA CONTENT TO RESILIENCY AS DEVELOPED BY ROSTRON FOR SOUTH CAROLINA, OR TOWARD A REPEATED CONSOLIDATION TEST DEVELOPED BY SHEPHARD IN VIRGINIA. /BPR/
