摘要: |
The objectives of the research were to: (1) Demonstrate the value of RICM to accelerate construction, reduce re-work, and improve uniformity of pavement layers. (2) Evaluate the reliability and potential use of RICM data for acceptance and measurements of in-situ stiffness of the constructed earth materials, linking to properties that relate more directly to design (e.g., modulus), and in-service performance. (3) Establish long-term monitoring sections and monitoring protocols/assessments for LTRC to document the impact of implementing these technologies and specification approaches. (4) Demonstrate Strategic Highway Research Program (SHRP) 2 R-07 performance specifications for rapid renewal using non-destructive RICM technology and mechanistic-based in-situ point measurements on a new pavement section including subgrade, stabilized subgrade, base course, and hot-mix asphalt (HMA) layers. |
