Accelerated Performance Testing on the 2012 NCAT Pavement Test Track

The objectives of this research project will be: (1) Constructing 200 ft test sections on the existing 1.7-mile National Center for Asphalt Technology (NCAT) test oval that are representative of in-service roadways; (2) Applying accelerated performance truck traffic in the 2 years following construction; (3) Assessing/comparing the functional and structural field performance of trafficked sections on a regular basis via surface and subsurface measures; (4) Validating/calibrating new & existing mechanistic-empirical (M-E) approaches to pavement analysis and design using pavement surface condition, pavement load response, precise traffic and environmental logging, and cumulative damage; (5) Determining the life cycle cost of various pavement preservation alternatives in a highly controlled experiment that will provide state Departments of Transportation (DOTs) with the financial foundation to begin to build a decision tree for their own maintenance program; (6) Correlating field results with laboratory data for both mechanistic and preservation applications; and (7) Answering practical questions posed by research sponsors through formal (i.e., reports and technical papers) and informal (e.g., one-on-one responses to sponsor inquiries) technology transfer.
