Accelerated Performance Testing on the 2021 NCAT Pavement Test Track with MnROAD Research Partnership

The primary objectives of the pooled fund project described herein will be: (1) Constructing experimental pavements on the existing 1.7-mile NCAT test oval and the MnROAD mainline bypass that are representative of in-service roadways on the open transportation infrastructure; (2) Applying accelerated performance truck traffic after construction for the duration of the 3-year research cycle; (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 and existing methodologies for analysis and design using pavement surface condition, pavement load response, precise traffic and environmental logging, and cumulative damage; (5) Correlating field results with laboratory data for both mix and structural performance; and (6) 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. For example, can pavement thickness be reduced as a result of the addition of premium mix additives, and if so does the thickness reduction offset the additional cost of construction?
