Evaluation of Long-Term Impacts of Early Opening of Concrete Pavements

Status: Active
Project Start Date: December 11, 2017
Project End Date: November 30, 2020

Project summary

This project will help to establish a method for determining when a Portland Cement Concrete (PCC) pavement or patch can be opened earliest to traffic without compromising its long-term performance. To achieve it, the very early-age fatigue damage and associated long-term distress in PCC pavement subjected to early opening will be evaluated and monitored. This will verify early-opening methodologies recent research has proposed. The objectives of this study will be:

  • Evaluate visible and non-visible immediate and long-term damage caused by early age loading. To achieve it, a comprehensive analysis of sensor reading and non-destructive test results should be conducted.
  • Quantify the effect of early loading damage on long-term performance.
  • Determine minimum strength at opening or other measurable variables associated with this parameter.
  • Recommend strategies for minimizing or avoiding early loading damage detrimental to long-term performance.
