• Abstract:
  Two bonded concrete overlay rehabilitation projects were constructed in Illinois during the 1990?s. The first project was constructed in 1994 and 1995 on Interstate 80, east of Moline. The second project was constructed in 1996 on Interstate 88 near Erie. The existing pavements for both the Interstate 80 and Interstate 88 projects were 8-inch thick continuously reinforced concrete pavements. The Interstate 80 rehabilitation was designed as a 4-inch thick plain concrete overlay. This project includes six experimental sections using various percentages of microsilica added to the standard mix design. In
  
  addition, microsilica grout was used as a bonding agent between the original pavement and the new bonded concrete overlay in some sections. The Interstate 88 project was designed as a 3-inch thick plain concrete overlay. This project includes two experimental sections, which incorporate different surface preparation methods prior to the overlay placement. This report summarizes the performance of these two bonded concrete overlays. The design, construction, maintenance, and costs of these projects are addressed. Visual distress surveys were conducted annually for both the Interstate 80 and
  
  Interstate 88 projects. In addition, these projects were tested annually for an International Roughness Index value. Condition Rating Surveys were conducted every two years to define the overall condition of the pavement. Results of these tests and visual surveys are included within this report. The performance of these two projects has been quite different. The Interstate 80 project has shown significant distress, and was in need of maintenance only four years after construction. The Interstate 88 project has not developed significant
  
  early distresses. Potential explanations for the difference in performance, including initial pavement condition, traffic
  
  volume, and overlay construction are explored.
