FLEXIBLE PAVEMENT RESEARCH IN SOUTH DAKOTA
IN 1961 THE SOUTH DAKOTA DEPARTMENT OF HIGHWAYS COMPLETED THE SECOND YEAR OF A THREE-YEAR FLEXIBLE PAVEMENT STUDY. THIS STUDY IS INTENDED TO EVALUATE DESIGN PROCEDURES PRESENTLY IN USE IN SOUTH DAKOTA. THIRTY-FOUR PROJECTS, TOTALING APPROXIMATELY 425 MILES OF HIGHWAY WERE SELECTED AS BEING REPRESENTATIVE OF THE VARIOUS DESIGNS OF HIGHWAYS CURRENTLY BEING CONSTRUCTED. THESE TEST PROJECTS ARE BEING EVALUATED IN TERMS OF PERFORMANCE AND COST. PERFORMANCE IS BEING DETERMINED THROUGH CONDITION SURVEYS, ROAD ROUGHNESS DETERMINATIONS, PLATE BEARING TESTS, AND BEAM DEFLECTION TESTS. INITIAL CONSTRUCTION COSTS AND ANNUAL MAINTENANCE COSTS DURING THE LIFE OF THE PROJECT ARE BEING RECORDED TO COMPARE WITH PERFORMANCE DATA. OTHER FACTORS WHICH INFLUENCE PERFORMANCE AND COST ARE ALSO BEING STUDIED. THESE INCLUDE THE AMOUNT AND TYPE OF TRAFFIC, TYPE OF SOIL, GEOLOGY, AND CLIMATE, AND THE QUALITY OF THE VARIOUS MATERIALS USED IN CONSTRUCTING THE HIGHWAY. THE RESULTS OF THIS STUDY WILL NOT BE AVAILABLE UNTIL AFTER THE THIRD YEAR OF TESTING. HOWEVER, THE PROCEDURES BEING USED, THE ALTERATIONS MADE IN PROCEDURES, THE EQUIPMENT BEING USED, MODIFICATIONS MADE IN THE EQUIPMENT, AND SOME OF THE PRELIMINARY RESULTS OF THE STUDY ARE DISCUSSED IN THIS PAPER. /AUTHOR/
