Demonstration Projects for Engineering the Foundation Layers for Long-Life Pavement Systems

Main study objectives include: (1) Provide technical support to SHAs for building long-life pavement systems pilot projects using optimized pavement and foundation design solutions that achieve the design assumptions for the foundation materials, including developing a Quality Assurance Program (QA) that addressed field performance verification measurements during construction. Technical support elements include: a. Determine, on statewide basis (representative materials), if the design values are being achieved using spot plate load tests. The test results will be used to populate a database for each SHA with results of what is being achieved for various foundation materials with current specifications compared to design assumptions. This data is strategic in understanding where there is opportunity to significantly improve pavement performance and optimize designs. b. Determine, at project level, if the construction quality verification is delivering design modulus and verify with 100% mapping. c. Establish a process for QA in compliance with 23 CFR Part 637, Subpart B (Quality Assurance Procedures for Construction) and provide technical assistance to SHA. d. Develop draft specifications that incentivize quality the foundation layers. (2) Develop the methodology for a modern pavement foundation design.
