On May 18, 2015, jointed plain concrete (JPC) paving began on one of nine performance-related specification (PRS) contracts along the Jane Addams Tollway (I-90) west of Chicago. The nine contracts consisted of reconstruction and widening projects for the pavement and bridges that carry between 40,000 and 80,000 vehicles per day into and out of the City of Chicago. While the contracts included a host of activities and pay items, the JPC pavements that will make up the mainline lanes of I-90 were all built according to the Illinois Tollway PRS Special Provision. Overall, approximately 750,000 square yards of JPC were placed in 2015 using PRS pay factor adjustments based on how the contractors performed relative to the target values in five performance categories: plastic air content, thickness, dowel alignment, 28-day compressive strength, and pavement surface smoothness. To manage all of the data collected for the PRS projects, a summary spreadsheet was established for each contract. All data are stored and reported by sublot, and the data are used to calculate the individual pay factors specific to each quality characteristic, as well as the overall pay factor for the contract.

This paper was sponsored by TRB committee AFH20 Standing Committee on Quality Assurance Management.
