Accelerated Performance Testing on the 2006 NCAT Pavement Test Track

The primary objectives of the pooled fund project described herein will be: (1) Constructing 200 ft test sections on the existing 1.7 mile NCAT test oval that are representative of in-service roadways on the open transportation infrastructure; (2) Applying a design lifetime of 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 the M-E approach to pavement analysis and design using both surface and subsurface measures; (5)Calibrating new and existing M-E approaches to pavement analysis and design using pavement surface condition, pavement load response, precise traffic and environmental logging, and cumulative damage; (6) Correlating field results with laboratory data; and (7)Answering practical questions posed by research sponsors. For example, can an innovative mix design utilized in one state be implemented in another sponsor's practice using locally available aggregates? Will a specific material source provide for a safe roadway surface if adopted for widespread use? If not, what maximum percentage will work?
