Analysis and Feasibility of Asphalt Pavement Performance-Based Testing Specifications for the Wisconsin Department of Transportation

Efforts to improve the sustainability and performance of asphaltic mixtures have led to innovations within the pavement industry for new materials and production methods. Specific examples include use of binder modifiers including polymers, extender oils and WMA (Warm Mix Asphalt) additives, use of higher recycled materials content involving both recycled asphalt pavement (RAP) and recycled asphalt shingles (RAS) and plant modifications (i.e. foaming). Research at the federal level has introduced new test methods and a design methodology that are more closely related to in-service performance through enhanced material characterization by considering loading time, temperature, and aging. In addition, the concepts of visualization and force measurement during compaction have been recently upgraded by providing direct measurements of mixture aggregate structure and shear stability versus estimation based on density. In contrast to these technological improvements, methods used to accept mixtures during production and placement (i.e. volumetric properties and density) remain unchanged and may not be indicative of performance. Given the maturity of recently developed test methods, there is a need to define a performance-based mixture acceptance framework that applies to the mix design, production, and placement phases of constructing asphaltic mixtures. The framework will include both tests that measure mixture properties directly and methods to estimate mixture performance that are suitable for use as quality control and acceptance tests. The aim of this research is to develop a performance-based acceptance framework that applies to both mixture design and quality control/acceptance during production and further to assess the feasibility of implementing this framework into Wisconsin Department of Transportation's (WisDOT’s) asphalt pavement mixture design and quality management program (QMP). The objectives of this research are to develop criteria for selection of candidate test methods and a process for prioritizing which properties will be measured in the performance-based hot mix asphalt (HMA) evaluation framework, identify and validate surrogate measures of performance for use during production and acceptance testing, and quantify the benefits and identify the challenges of implementing a performance-based framework of mix acceptance through comparison of outcomes to current practice.
