Abstract:

Instructions are provided for users of the program RENU which provides methodology for determining the effects of changes in truck size, weight, and configuration on pavement performance and for relating these effects to pavement maintenance and rehabilitation needs and costs. This manual summarizes the evaluation procedure, describes all input parameters and data sources, and describes RENU usage together with examples. The procedure evaluates the effect of legal load limit changes on the life cycle costs of flexible, rigid, and/or composite pavements. Eighty representative design sections are grouped by system classifications of highways. A maximum of 10 different truck types are allowed along with various axle and tire configurations. While truck axle weight and configuration are the major variables considered, new trucks, such as triple trailer units can be included in the procedure. A computerized gross vehicle weight and axle load distribution shifting procedure to assess the impact of changes in current legal load limits is provided. Users may select different maintenance and rehabilitation cost models. The procedure also allows evaluation of a small road network, district, or state.
