This website aims 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 led to the historic adoption of the Falling Weight Deflectometer (FWD) test, which for many situations provided both fast and cost-effective results. In some cases (usually smaller projects) it has been appropriate to use the instrumented Benkelman Beam (GEOBEAM), as necessary.
The demand for the FWD technique 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)
More recently the Traffic Speed Deflectometer has enabled very cost efficient production of essentially continuous structural data usually from only one wheelpath. The latest TSD design now provides even greater accuracy and both wheelpaths may be tested. The latest technology totally transforms the discipline of pavement engineering and an entirely new approach is now warranted for all highways. Local authority roads (low volume, slow speed or with significant corners) are not suitable for TSD but new developments are becoming available from recent improvements in technology. (See FUTURES tab above).
