| 摘要： | Precast concrete inlay panels (PCIPs) are a new rapid repair technique developed to address deep-seated rutting issues in asphalt pavements. Providing a uniform, stable support layer for precast concrete pavement is critical to its performance, and constructibility of this support is a key factor in the feasibility of PCIPs as an overnight repair technique. Three methods of PCIP support (asphalt supported, grade supported, and grout supported) were developed, designed, and constructed in a trial installation in Ontario, Canada. An analytic hierarchy process (AHP) analysis was performed to evaluate the performance of the options based on four construction-related criteria: cost, installation rate, repeatability, and resiliency. Input from the construction contractor and the Ministry of Transportation of Ontario was considered. This paper describes the support options, trial construction operations, and AHP evaluation. The results indicate that the grout-supported condition is most favorable and is recommended for future applications of PCIP for conditions similar to the trial section. |
