A SYSTEM FOR ESTIMATING PRESENT SURFACE CONDITION AND REMAINING SERVICE LIFE OF EXISTING PAVEMENT SECTIONS

THOSE CONCERNED WITH THE CONDITION OF HIGHWAY SURFACES AND HOW LONG PAVEMENTS WILL LAST BEFORE THEY NEED RESURFACING WILL BE INTERESTED IN THE SYSTEM PRESENTED HERE FOR ESTIMATING PRESENT SURFACE CONDITION AND REMAINING SERVICE LIFE OF EXISTING HIGHWAY PAVEMENTS. FINDINGS FROM THE AASHO ROAD TEST AT OTTAWA, ILL. ARE USED, TO DEVELOP THE SYSTEM WHICH FEATURES A SET OF NOMOGRAPHS TO SPEED UP CALCULATIONS. THE PROCEDURE, BASED ON THE SERVICEABILITY-PERFORMANCE CONCEPT ESTABLISHED IN TTHE ROAD TEST, IS INTENDED TO MINIMIZE SUBJECTIVE JUDGMENT, COMMONLY TERMED "THE HUMAN FACTOR" IN EVALUATIONS OF PAVEMENT CONDITION AND IN ESTIMATES OF REMAINING SERVICE LIFE. THE PERTINENT RESEARCH FINDINGS FROM THE AASHO ROAD TEST, ARE REVIEWED, WHICH, IN ADDITION TO THE PAVEMENT SERVICEABILITY-PERFORMANCE CONCEPT, INCLUDE PAVEMENT PERFORMANCE EQUATIONS AND AN EQUIVALENT AXLE-LOAD CONCEPT. PROCEEDING FROM CONCEPT TO PRACTICAL METHOD THEY THEN OUTLINE REQUIREMENTS FOR DEVELOPING A SYSTEM AND DESCRIBE USE OF THE SERVICE-LIFE NOMOGRAPHS. /AUTHOR/
