WK92337 - New Test Method for Pavement Deflection Velocity Measurement with a Traffic Speed Deflection Device (TSDD) that uses Laser Doppler Vibrometers

Work Item

ASTM WK92337

New Test Method for Pavement Deflection Velocity Measurement with a Traffic Speed Deflection Device (TSDD) that uses Laser Doppler Vibrometers

1. Scope

This practice covers collection of pavement deflection velocity data using a traffic speed deflection device (TSDD) that uses Laser Doppler Vibrometers (LDVs).

Keywords

traffic speed deflection device; TSDD; pavement deflection; pavement structural condition; Doppler laser; laser Doppler vibrometer

Rationale

No standard exists in the US that specifies the components of a LDV-based traffic speed deflection device, how to operate such a device, or what data should be reported from such a device. The new standard will be used by pavement owners (primarily Departments of Transportation) to request collection of pavement structural condition data using LDV-based TSDDs. Providers of TSDD testing will use the standard to ensure they are meeting minimum requirements for data collection and delivery.
