  • Abstract:
    State Legislation requires that cost responsibility studies be available for the 1991 and 1993 Legislative sessions. Part of this legislative requirement includes the need to re-evaluate and establish a sound basis for the weight-mile tax. To be fair and equitable, this tax should reflect the relative contribution of environment factors and traffic loading to pavement deterioration. Researchers at Oregon State University recently developed the computer program PBA(Performance Based Approach) for determination of the degree to which pavement deterioration is due to load and non-load related factors (Ordonez and Vinson, 1988). This program is based on the methodology developed by researchers at Purdue University (Fwa and Sinha, 1984) for the State of Indiana's cost allocation study. Evaluation of the PBA methodology and the ability to implement it within Oregon is required prior to attempting to use the method to determine pavement deterioration cost responsibilities.

    The objectives of this study were twofold:

    1) Determine the validity of the PBA methodology and the viability of using the PBA method in Oregon for evaluation of the proportion of load related and non-load related responsibility in pavement deterioration.

    2) Develop a course of action to determine the proportion of load vs. non-load related responsibility in pavement deterioration.
