Selection of Optimum Pavement Treatment Type and Timing at the Project Level

Various pavement treatments are implemented to correct or reduce the existing surface distresses and correct the causes of distress. Certain pavement treatment types correct or reduce certain pavement distresses and their causes. The identification of the appropriate alternative pavement treatment types that would correct or reduce the surface distress is based on the pavement distress data (type, severity, and extent of distress). Whereas, the identification of appropriate alternative pavement treatments that would correct the causes of pavement distress is based on the distress type and results of the forensic investigation of the pavement section. The candidate set of pavement treatments should be those that correct most, if not all, pavement distresses and their causes. The candidate pavement treatments can be applied at varying times resulting in varying costs and pavement performance. In general, the benefits and costs of the treatments are functions of the conditions and the rates of deterioration of the pavement structure and the time at which they are applied. The preferred pavement treatment type and application time are determined through cost/benefit analyses to maximize benefits and minimize costs. This paper discusses a methodology for the selection of optimum pavement treatment type and timing at the project level. The impacts of several functional relationships between pavement condition and rate of deterioration and costs, performance, and benefits are discussed. It is shown that the selection methodology can be applied over the life of the pavement section (several treatment cycles) to determine the optimum project level treatment strategy.
