| Project detail | ||
| Roadmap/Focus area(s): | Infrastructure Research and Technology Strategic Plan and Roadmap | |
| 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. | |
| Goals: | The key project objective is to develop improved falling weight deflectometer (FWD) calibration procedures, which is critical to reliable and effective pavement design. | |

| Field Test: | deflection testing using Falling Weight Deflectometers | |
| Product Type: | Data Draft standard, specifications, or guidelines Hardware Promotional materials Research report Software Training materials | |
| Test Methodology: | field testing, data analysis | |
| Expected Benefits: | The calibration of the falling weight deflectometer provides the best assurance for the accuracy of deflection data and analysis results on all types of falling weight deflectometer applications, including estimating the remaining service life, forensics, and pavement rehabilitation design. The additional calibration centers will provide States access to free falling weight deflectometer calibration services with closer geographic proximity. | |
