Survey of current practices of using falling weight deflectometers (FWD)

In May 2001, the Florida Department of Transportation (FDOT) distributed a survey questionnaire to the 51 State Departments of Transportation (DOTs), and to 3 Canadian provinces including British Columbia, Ontario, and Quebec. The objective was to assess the current practices of using the Falling Weight Deflectometer (FWD) by these highway agencies, and to gather some related facts and figures of interest to FWD users. This report provides a summary of the survey results based on the responses received from the user agencies. The questionnaire targeted three FWD related program areas including field operations, pavement design parameters, and program management.
