Abstract
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.
