Abstract
A methodology is presented that was developed for use in a 1983-1984 Indiana highway cost-allocation study to determine the responsibilities of load-related and non-load-related factors for pavement routine maintenance and rehabilitation costs. Proportions of the effects of the two types of factors are derived by comparing actual pavement performance curves with predicted pavement performance by using design equations. A technique is presented to estimate the amount of total pavement damage caused by load-related and non-load-related factors combined. The cost-responsibility proportions of the two types of factors are then computed. An example is given to illustrate the application of the procedure.
