BITUMINOUS OVERLAY STRATEGIES FOR PREVENTIVE MAINTENANCE ON PENNSYLVANIA INTERSTATE ROADWAYS.
Master's Thesis, University of Pittsburgh.
(Unpublished)
Abstract
In 2008, Penn DOT initiated a two-stage process to identify appropriate bituminous overlay strategies for interstate pavements. The first stage consisted of a comprehensive review of the preventive maintenance practices and best practices at a national level and the second stage involved the identification of practices within each district in Pennsylvania. Identification of the most effective practices, both locally and nationally, can be used as a lead-in to the implementation of a strategy for the use of preventive maintenance procedures on interstate and interstate look-alike pavements in Pennsylvania. The research approach involved an extensive literature review to identify the preventive maintenance practices, and outline the key elements or factors influencing these practices. The most common techniques observed are thin hot mix asphalt overlays, microsurfacing, chip sealing, crack seal, and polymer modified hot mix asphalt overlay. The factors influencing these techniques include climate, traffic conditions, relevant geography, life cycle costs, pavement performance indices, application temperature, service life, pavement distress, and pavement age. The literature review, state survey, and district survey results were used to generate a list of best preventive maintenance practices applicable in Pennsylvania. The identified techniques were also compared to findings from Long Term Pavement Performance data. The study concludes the best practices for preventive maintenance of Pennsylvania interstate pavements. The selected identified best practices can be implemented on experimental test sites to validate the findings of the study.
