Accelerated Performance Testing on the 2009 NCAT Pavement Test Track http://www.pooledfund.org/Details/Study/433 Record Type: RiP The National Center for Asphalt Technology (NCAT) Pavement Test Track was originally constructed as a result of interest and support from state departments of transportation (DOTs) who shared a concern for reducing and predicting distresses in their flexible pavements. The 2009 NCAT Pavement Test Track is expected to consist of an even larger structural experiment as well as more mill/inlay surface mixes, with formal research sponsorship expanded to include private sector partners. Track research sponsors have always been encouraged to choose experiments that meet their specific research needs. Individualized test sections will still be optional on the 2009 Track; however, NCAT is also encouraging sponsors to consider supporting a pre-designed six section "Group Experiment" that is intended to encompass multiple timely issues that are important to the entire pavement community. 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 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 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 through formal (i.e., reports and technical papers) and informal (e.g., one-on-one responses to sponsor inquiries) technology transfer. For example, can high reclaimed asphalt pavement (RAP) content mixes provide the same level of performance as virgin mixes? If so, can they be used in both deep and shallow layers? Although warm mix is better for the environment, will it provide the same level of rut and moisture damage resistance as conventional mixes?
