Abstract

This paper describes the concept of a marginal cost method for quantitatively assessing the relative shares of load and non-load factors for pavement routine maintenance expenditures. A set of statistical models was formulated using an aggregate pavement performance approach to relate pavement routine maintenance expenditures with traffic loading and various non-load factors. The models considered the simultaneity between pavement performance and maintenance. For the Indiana state highway system, the load and non-load shares were found to be 26-74 for flexible pavements, 36-64 and 63-37 for jointed concrete pavements (JCP) and continuously reinforced concrete (CRC) pavements, and 30-70 for composite pavements. The results of this study will facilitate the apportionment of pavement routine maintenance expenditures for highway cost allocation in a fair and equitable manner. This paper is previously published in the 20th ARRB Transport Research Conference, held Melbourne 2001, and for the abstract see also ITRD E204222.
