TMF Measurement Vehicle
for the determination of pavement texture depth according to EN ISO 13473-1:2004 – fast and precise in flowing traffic
Pavement surfaces with reduced noise emissions as well as sufficient water drainage and skid resistance are important requirements for environmental sustainability and road safety.
The quality assurance of these pavement properties requires the definition of the right needs-based parameters for the characteristics of the micro- and macrotexture and their monitoring.
The TMF measurement vehicle with its high-resolution laser sensor measures the texture depth continuously in flowing traffic along a chosen test line with great precision.
The PC-system for measurement control and data storage is integrated in the vehicle. The system is operated via a touchscreen monitor.
An integrated GPS system with a DGPS correction system permits precise localization of the measured data in addition to the speedometer data.
The „TextureViewer“ software tool generates the necessary evaluations and graphical presentations.
