With 50 years serving the pavement preservation industry, the International Slurry Surfacing Association (ISSA) is proud to be a supporter of the National Center for Asphalt Technology’s (NCAT) Pavement Preservation Effectiveness Study, the fifth cycle of the Pavement Test Track. Performance monitoring of pavement preservation treatments in this cycle of the Pavement Test Track and on 2,500 ft. (762 m) of Lee Road 159 in Alabama will allow researchers to determine the service life extension of various pavement preservation techniques relative to pretreatment condition and explore ways to stretch transportation budgets. Seven state departments of transportation and multiple private sponsors have stepped forward to support the expansion of the scope of this research project to include proactive maintenance methods. These methods include those that ISSA supports, slurry and micro surfacing, chip sealing and crack treatment, among others and will be used alone or in combination to test several methods in varying circumstances. ISSA is not only donating funding to this project, but the members that drive the association are donating their time, knowledge, expertise and even equipment to help facilitate proper pretreatment to post-treatment condition comparisons.
“This three-year study should be great for the pavement preservation industry,” stated Doug Ford, 2012 ISSA president. “It will provide quantified results for each process and insight into the timing and processes that best address each level of deterioration.
