A prototype Rolling Weight Deflectometer (RWD) ... It is anticipated that a highway version of the RWD will be produced jointly by Quest Integrated and Dynatest Consulting, Inc., within the next two years that will collect deflections at highway speeds of 70 to 80 kph (45 to 50 mph).
Jul 11, 2018 · Two new technologies for nondestructive testing offer key benefits, one suiting road surfaces, the other suiting concrete structures Kristina Smith reports Dynatest has developed a new way to measure and record the state of pavements, using a machine that travels at the same speed as traffic. The Rapid Pavement Tester (Raptor) has been seven years in the making and offers road .
Jun 28, 2017 Dynatest FASTFWD, 5 times faster testing and data collection, compared to the conventional FWDs, high accuracy levels and adhering to all the standards, user can collect 75% more tests per hour and 45% less traffic exposure. Aimil Ltd is .
This rolling weight deflectometer (RWD) optically measures the maximum amplitude of the depression basin using a new type of laser sensor that operates on the principle of triangulation. Four sensors that are mounted on a beam make pavement measurements. The key to producing accurate results is the requirement that the sensors remain in a ...

(1) Resilient modulus and indirect tensile strength were measured after the curing time. (2) soft asphalt. (3) hard asphalt. Additionally, Meocci et al. [2] noted that the commonly used accelerated curing process (72 h at 40°C) did not allow the definitive mixture strength and stiffness to be reached, obtaining higher values after 10 days, a behavior that should also be evaluated in this ...

· a Dynatest falling weight deflectometer (FWD) for nondestructive testing and evaluation of flexible pavements using a peak load of 7 to 120 kN (1,500 to 27,000) lbf; a van for towing and controlling either the HWD or FWD on or off campus, with a .
· Field and laboratory testing programs were conducted to develop models that predict the resilient modulus (M r) of subgrade soils from the falling weight deflectometer (FWD) test r is used in the design and evaluation of pavement structures. The field testing program included testing various sections in 10 pavement projects within Louisiana.
August 2020 : Using the Light Weight Deflectometer in Winter Climates : A. Menke, W. Wieder, and S. Shoop ... The light weight deflectometer (LWD) was designed to test the compaction ... testing was conducted with the Dynatest 3031 LWD on a variety of groomed snow surfaces at two field sites, in Montana and Michigan, during the ...
A rolling weight deflectometer (RWD) is a defletometer that can collect data at a much higher speed (at most as 55 mph) compared to the FWD, which allows data to collect data without traffic control and closure of the lane. [8] It is implemented as a tractortrailer with laser measuring devices mounted on a radius under the trailer.
Dynatest went on to develop the first Heavy Weight Deflectometer and more recently the FastFWD. In the late 90s Dynatest entered the "mature" profiling market developing the Road Surface Profiler.
