A determination of load and non-load shares of highway pavement routine maintenance expenditures

This paper describes the concept of a marginal cost method for quantitatively assessing the relative share of load and non-load factors for pavement routine maintenance expenditures. A set of statistical models has been formulated using an aggregate pavement performance approach to relate pavement routine maintenance expenditures with load and various non-load factors. The models have considered the correlation between pavement performance and maintenance. For the Indiana State Highway network, the load and non-load shares are found to be 26:74 for flexible pavements, 36:64 and 63:37 for jointed concrete pavements and continuously reinforced concrete pavements, and 28:72 for composite pavements. The results of this study will facilitate the apportionment of pavement routine maintenance expenditure for highway cost allocation in a fair and equitable manner.
