Project Details

Project Description: 

Support activities of the pooled fund study by performing quality assurance reviews of the State-hosted calibration centers, attend and facilitate Technical Advisory Committee meetings, see the American Association of State Highway and Transportation Officials falling weight deflectometer calibration standard through the review process, and publish the final reports.


The key project objective is to develop improved falling weight deflectometer (FWD) calibration procedures, which is critical to reliable and effective pavement design.

Project Findings: 

Improved falling weight deflectometer (FWD) calibration procedures.
