EXPLANATION OF MAINTENANCE VARIANCE: AN ANALYSIS OF SASHTO STATES

In an effort to better explain maintenance cost variation between states, a standardized questionnaire survey was made of all SASHTO states plus Oklahoma and Texas. Definitions of overhead costs, were standardized, and all costs attributable to the maintenance organization were considered. Reporting problems are discussed, and the reported data are analyzed and tabulated. Individual prediction equations were developed for each area of expenditure, and a sample equation is shown. The study which produced consistent results, also found that a much better explanation of variation between states can be realized if more than one physical variable is used to account for the variation in expenditure. Greater understanding of the effect of the physical system variables on the allocation of resources could be achieved if states could develop standardized reporting systems that would allow interchange of information.
