Project Title:
  Evaluation of the Long-Term Durability of Joints Cut Using Early-Entry Saws on Rigid Pavements
Start Date: 11/1/2008
End Date: 9/30/2010
Summary of Project:
  This project will establish the current national state-of-the-practice regarding the use of early entry sawing for concrete pavements, and discuss how it differ from IDOT’s current conventional wet sawing technique. Differences in freeze-thaw durability and resistance to deicers between conventionally sawed joints and early entry sawed joints will be determined. Based on the collected data, is will be determined whether the early entry saw technique is viable for IDOT work.
Objective of Project:
  To evaluate the expected joint durability of no-seal joints when cut using early entry techniques compared to IDOT’s standard practice for saw cuts. The joint performance as a function of cut depth and time shall also be considered.
Expected Outcome:
  • A brief synthesis on the early-entry sawing technique, including current practices in other states. • A thorough documentation of the construction process for an early-entry sawing project including a summary document, field notes, photographs, and video clips. • A final report, detailing the construction monitoring, laboratory testing, and data analysis, will be provided. It will include definitive conclusions that IDOT can use in determining the viability of using early entry sawing technique and recommendations for future work will be made.
