INITIAL PROBLEMS CONFRONTED IN THE KENTUCKY INCREMENTAL-COST STUDY

DIFFICULTIES ARE DISCUSSED OF THE DECISIONS IN DEFINING WHAT IS THE BASIC VEHICLE AND THE BASIC ROAD. IN AN INCREMENTAL-COST STUDY, IT IS ESSENTIAL THAT INCREMENTS IN PAVEMENT DESIGN STANDARDS BE BASED ON BOTH AXLE LOADS AND TRAFFIC VOLUME. THE METHOD OF HIGHWAY CLASSIFICATION, WHEN FOLLOWED IN KENTUCKY, LED TO FOURTEEN BASIC DESIGN STANDARDS FOR RURAL ROADS. WHEN OTHER MODIFICATIONS WERE COUNTED, A GRAND TOTAL OF THIRTY-FOUR CLEARLY IDENTIFIED STANDARDS RESULTED. THE DETERMINATION OF MAINTENANCE COSTS AND THE CONSTRUCTION OF MAINTENANCE-COST INDEXES ALSO PRESENTED MANY PROBLEMS WHICH ARE DISCUSSED.
