NCHRP 20-07/Task 327 [Completed]

Developing Recalibrated Concrete Pavement Performance Models for the Mechanistic-Empirical Pavement Design
[ NCHRP 20-07 (Research for AASHTO Standing Committee on Highways) ]

  Project Data
Funds: $100,000
Research Agency: University of Pittsburgh
Principal Investigator: Juli M. Vandenbossche
Effective Date: 11/19/2012
Completion Date: 5/9/2014

 

The research is complete.  The project reviewed earlier work dealing with the consideration of the concrete's coefficient of thermal expansion in the performance-prediction models of concrete pavements and developed calibrated models that appropriately consider the coefficient of thermal expansion values obtained from laboratory tests.  The findings were presented to the AASHTO Joint Technical Committee on Pavements in late April 2014; copies of the final report were provided to the committee in mid May 2014 to facilitate their review and action. The committee decided to incorporate these models into the AASHTOWare Pavement ME Design.
