MARGINAL MAINTENANCE AND REHABILITATION COSTS. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN
User charge responsibilities (UCR's) for pavement maintenance and rehabilitation (M&R) were calculated using the efficiency-based cost allocation scheme. The steps necessary to satisfy the method involve use of the Economic Analysis of Roadway Occupancy for Maintenance and Rehabilitation (EAROMAR) model to calculate agency pavement M&R costs for various traffic volumes. The types of damage predicted are those most prevalent to both rigid and flexible pavements such as rutting, cracking, loss of Pavement Serviceability Index (PSI), faulting, and pumping. The M&R activities prolong the service life or restore structural capacity. Policy dictates the trigger values wherein the damage is repaired. The rate of change of pavement M&R costs with respect to vehicle equivalent single axle load (ESAL) level (marginal cost) is then determined by linear regression. The UCR's for various types of vehicles are calculated by multiplication of the marginal cost by the vehicle-ESAL factor for each vehicle class. Reasons for the difference between the results of the Federal Highway Administration's (FHWA's) Research, Development, and Technology (RD&T), and the Massachusetts Institute of Technology (MIT) studies are discussed. The asphalt grade, vehicle-ESAL factor, pavement structural capacity, and overlay models are evaluated. Based on the FHWA RD&T runs, you can conclude marginal M&R costs are relatively independent of pavement type and environmental zone. The major finding is the relationship between marginal costs and pavement thickness; i.e., thicker pavements had lower marginal costs. Hypothetically, increased traffic has less effect on stronger pavement systems.
