FLEXIBLE PAVEMENT PERFORMANCE STUDIES IN ARKANSAS
THIS PAPER REPORTS THE TEST METHODS USED AND RESULTS OBTAINED IN EVALUATING THE PERFORMANCE OF 115 MI OF FLEXIBLE PAVEMENT. THE PAVEMENT VARIES IN AGE FROM THREE TO EIGHT YEARS, FROM HIGH-TYPE ASPHALTIC CONCRETE IN EXCELLENT CONDITION TO DOUBLE SURFACE TREATMENTS THAT HAVE REQUIRED EXTENSIVE MAINTENANCE. ALL OF THE ROADS ARE ON THE SAME SOIL AREA AND HAVE SIMILAR CLIMATIC CONDITIONS. THE DEFLECTIONS WERE MEASURED BY THE BENKELMAN BEAM WITH HELMER RECORDER. SEVEN SERIES OF DEFLECTIONS WERE MADE OVER A PERIOD OF TWO YEARS AT SOME 500 DIFFERENT STATIONS. IN-PLACE DENSITIES AND MOISTURE CONTENTS WERE DETERMINED AT ABOUT ONE-THIRD OF THESE STATIONS. ALSO MOISTURE-DENSITY SAMPLES OF THE SUBGRADE WERE TAKEN AT THE EDGE OF THE PAVEMENT AT DIFFERENT SEASONS TO STUDY THE VARIATIONS OF MOISTURE AND DENSITY WITH TIME. PHYSICAL PROPERTIES OF SUBGRADE AND BASE MATERIALS ARE ALSO REPORTED. VISUAL CONDITION SURVEYS WERE MADE AT FREQUENT INTERVALS DURING THE LIFE OF THE PROJECT TO DETECT CHANGES IN THE PAVEMENT CONDITION. /AUTHOR/
