Design of Surface Treatments with Reclaimed Asphalt Pavement Aggregates in Nevada (NDOT 778-24-803)
Surface treatments (STs), including chip seals and slurry and microsurfacing, are effective methods for maintaining asphalt concrete (AC) pavements. Using reclaimed asphalt pavement (RAP) as aggregates for STs conserves natural resources and promotes the design and construction of sustainable pavements. However, related changes in mix design and construction must be addressed for effective implementation. Although some national research has been conducted on the use of RAP as ST aggregates, the unique characteristics of Nevada’s asphalt mixtures, such as lime treatment and polymer-modified asphalt binders, limits the applicability of existing findings from the literature. The overall objective of this research is to develop test methods and procedures for the implementation of RAP materials from Nevada as aggregates for STs. The methods and procedures shall cover all aspects of materials selection, mix design, and quality assurance during construction. This research will include developing and conducting laboratory and field tests/methods for the evaluation of RAP materials as aggregates for ST, using locally available sources from each of the three Nevada Department of Transportation (NDOT) districts.
