Rolling Wheel Deflectometer (RWD) Demonstration for the Kansas Department of Transportation (KDOT)
The Rolling Wheel Deflectometer (RWD) is an innovative device to efficiently measure continuous pavement deflections at normal highway speeds. This previously-not-available data presents many potential benefits to pavement managers and highway agencies, mainly by measuring pavement structural response for use in network-level pavement evaluation and management. This report summarizes a pilot study performed for the Kansas Department of Transportation (KDOT). Applied Research Associates (ARA), Inc. performed RWD testing on 17 roadways, consisting of U.S., and state routes. The majority of roads included in this study were two-lane asphalt concrete (AC)-surfaced pavements. For each road, the RWD measured a continuous deflection profile in the outer wheel path in a single direction. The RWD operated at normal highway speeds, typically ranging from 50 to 65 mph. ARA tested 506 lane-miles over a 3-day period from July 28 to August 1, 2006 (one rest day). All roads were located in the Topeka region and selected by KDOT. ARA post-processed raw laser and distance (DMI) data to calculate deflection. A quality control process was followed to remove any non-representative RWD data due to truck and pavement factors, such as excessive truck bouncing at bridge joints.
