NEW TESTS FOR MEASURING ELASTICITY OF MICACEOUS SUBGRADES AND THEIR APPLICATION TO FLEXIBLE PAVEMENT DESIGN

THIS REPORT SUMMARIZES A STUDY /1/ OF FLEXIBLE PAVEMENT PERFORMANCE CONDUCTED BY CLEMSON COLLEGE FOR THE SOUTH CAROLINA HIGHWAY DEPARTMENT AND THE U. S. BUREAU OF PUBLIC ROADS. THE RESEARCH WAS INITIATED IN JULY 1960 TO DETERMINE THE CAUSE OF POOR FLEXIABLE PAVEMENT PERFORMANCE ON SEVERAL PRIMARY HIGHWAY SECTIONS AND TO RECOMMEND PROCEDURES FOR THE IMPROVEMENT OF PERFORMANCE IN FUTURE CONSTRUCTION. ROUTINE CLASSIFICATION, MOISTURE AND DENSITY TESTS OF THE SUBGRADE AS WELL AS TESTS OF THE PAVEMENT AND BASE WERE PERFORMED ON SITES OF WIDELY DIFFERING PERFORMANCE RATINGS. IN ADDITION TO THE ROUTINE TESTS, OTHER SPECIAL TESTS WERE ALSO PERFORMED. TEST RESULTS AND PAVEMENT PERFORMANCE WERE THEN CORRELATED WITH BENKELMAN BEAM DEFLECTION MEASUREMENTS TAKEN AT ALL TEST SITES AT DIFFERENT SEASONS FOR A PERIOD OF TWO YEARS. /AUTHOR/
