AASHO ROAD TEST FINDINGS APPLIED TO STATE HIGHWAY COST ALLOCATION STUDIES

RESULTS OF THE PAVEMENT EXPERIMENTS ON THE AASHO ROAD TEST HAVE BEEN APPLIED IN ALLOCATING COST RESPONSIBILITY TO MOTOR VEHICLE USERS IN COMPREHENSIVE STUDIES OF HIGHWAY FINANCE IN KANSAS AND SOUTH DAKOTA. THE ROAD TEST FORMULAS WERE USED IN APPORTIONING PAVEMENT COSTS AMONG VEHICLE CLASSES IN THE INCREMENTAL SOLUTION OF THE ALLOCATION PROBLEM. THE INCREMENTAL SOLUTION, WITH OTHER ALLOCATION SOLUTIONS AND TAX DATA, GUIDED THE FORMULATION OF RECOMMENDATIONS ON USER TAXATION. THE ROAD TEST EQUATIONS WERE USED AS A MODEL FOR PREDICTING PERFORMANCE UNDER TRAFFIC OF TYPICAL PAVEMENT STRUCTURE DESIGNS. THESE DESIGNS REFLECTED LOCAL CONDITIONS AND COSTS IN SEVERAL AREAS OF EACH STATE. PAVEMENT COSTS REPORTED IN HIGHWAY NEEDS STUDIES WERE THEN ALLOCATED TO USERS IN PROPORTION TO THEIR INFLUENCE ON PAVEMENT PERFORMANCE. THE PAVEMENT ALLOCATION WAS A RELATIVELY SMALL PART OF THE TOTAL USER RESPONSIBILITY, BUT FOR THE HEAVIER TRUCKS IT WAS A VERY SIGNIFICANT PART. THE INCREMENTAL SOLUTION TENDED TO ASSIGN GREATER RESPONSIBILITY TO LIGHT VEHICLES AND LESS TO HEAVY TRUCKS COMPARED WITH THE COST- FUNCTION SOLUTION OR THE AVERAGE OF THE VEHICLE-MILE AND TON-MILE SOLUTIONS. IN FORMULATING RECOMMENDATIONS, THE INCREMENTAL SOLUTION WAS PARTICULARLY USEFUL BECAUSE IT REFLECTED THE INFLUENCE OF VEHICLE TYPE AND AXLE CONFIGURATION. THE ROAD TEST EQUATIONS ASSIGN LESS RESPONSIBILITY TO TANDEM AXLE UNITS THAN TO SINGLE AXLES OF SIMILAR WEIGHT. /AUTHOR/
