We aim to provide a source of information of concepts relating to pavement structural testing and evaluation for rehabilitation treatment, asset evaluation and construction quality control.
The requirement for accurate and reliable evaluations of pavement structure has led to the adoption of the Falling Weight Deflectometer (FWD) test, which for most situations provides both fast and cost-effective results. In some cases (usually smaller projects) it is appropriate to use the instrumented Benkelman Beam (GEOBEAM), as necessary.
The increasing demand for the FWD technique has prompted the creation of this site, which aims to provide information for practitioners using or carrying out structural analysis using deflection data.
This site includes:
documentation on basic principles of testing and mechanistic design
complimentary downloads of published papers on FWD structural evaluation
pavement analysis tools
a section for Frequently Asked Questions (FAQ)
