Dynatest’s FastFWD8002 deflectomer picks up more points per hour

Pavement engineering specialist Dynatest has improved its best-selling falling weight deflectometer, allowing it to not just collect more data, but collect it faster. The Danish company said its FastFWD8002, which was unveiled at the Transportation Research Board annual meeting in Washington in January, is five times faster than the previous model. The FastFWD8002 collects 75% more test points per hour, meaning it can have around 45% less traffic exposure. The previous unit is upgradeable to FastFWD80

Pavement engineering specialist 2597 Dynatest has improved its best-selling falling weight deflectometer, allowing it to not just collect more data, but collect it faster.

The Danish company said its FastFWD8002, which was unveiled at the 2774 Transportation Research Board annual meeting in Washington in January, is five times faster than the previous model.

The FastFWD8002 collects 75% more test points per hour, meaning it can have around 45% less traffic exposure. The previous unit is upgradeable to FastFWD8002 specification.

The FastFWD8002, which does not use hydraulics, has the same sensor setup and user interface as the FWD model and so no major training of operators is needed. It is available as a trailer or a truck-mounted version meeting all FWD standards worldwide.

The deflectometer applies a dynamic load that simulates the loading of a moving wheel. The pavement response is analysed with Dynatest's ELMOD (Evaluation of Layer Moduli and Overlay Design) software to determine the elastic moduli, stresses and strains of each modelled layer. ELMOD reports the weakest layer of failure, residual life, and determines the optimum rehabilitation alternatives.

    Today’s highways require high performance materials, and this means rigorous testing as Patrick Smith reports Highways are under greater pressure than ever today and asphalts have to grant high performances in order to withstand traffic and meet the standards. Studying the plastic permanent deformations in hot mix asphalt (HMA) is very important to obtain useful information for mix designers as an appropriate mix design will reduce the formation of unevenness on road surface. To investigate the effect of mi

    Kevin Vine reports on the use of non-destructive testing for structural analysis of bridges Seven years ago, the overpass collapse in Laval, Québec that led to the death of five people brought to light severe issues with the state of the country’s bridges and transportation infrastructure. More recently, a crack in the Champlain Bridge to Montreal that forced over 160,000 commuters to find alternate routes to work reaffirmed a need for greater emphasis on early detection before a crisis occurs.
