The KUAB 2m-FWD is a trailer mounted dynamic impulse loading device which can be towed by any suitable towing vehicle.
The equipment is completely enclosed by a metal housing for protection against harmful elements,
and testing can be performed with all protective features in place.
Bay doors on the bottom of the housing open automatically during testing,
eliminating the need for the FWD operator to leave the tow vehicle.
The KUAB 2m-FWD meets or exceeds all of the requirements of ASTM Standard Test Method D 4694-96 and the SHRP calibration protocol for FWD equipment.
Following are a few of he unique features of KUAB 2m-FWD:
Two Mass Configuration: the most significant factor in the production of a load pulse that simulates the actual effects of a moving vehicle
Segmented Load Plate: which ensures an uniform pressure distribution over the full area of the plate
Seismometers: the deflection measuring sensors with a range of 0 to 200 mils (0 to 5080 microns)
The three most widely used models of the KUAB 2m-FWD vary primarily in loading capacity.
The KUAB 50 model is the lightest and most versatile testing system over a broad range of highway, street and parking lot pavements, with a standard load range of 3,000 to 14,000 lbs-force.
The KUAB 150 model offers a standard load range of 3,000 to 33,000 lbf.
making it a suitable testing device for airport pavements, as well.
The upper load limit of both machines can be modified to meet the needs of the client.
The largest KUAB 2m-FWD available, Model 150, is capable of generating a dynamic load of 66,000 lbf.
A special structural loading device, Model 600SP, to be delivered to US Navy got testing bridges and piers is under development.
This unique equipment is first of its kind in the world which can deliver a maximumload of 120,000 lbf.
