Riftek’s high speed laser triangulation sensors, available from Ixthus Instrumentation, have been selected for road surface profiling equipment


K-based PaveTesting (PaveTest) is a leading designer and manufacturer of pavement testing equipment for essential monitoring and maintenance tasks on road and runway surfaces. Its comprehensive product range covers measurement hardware and sophisticated software that conforms to international safety standards for the identification of pavement surface profile characteristics that include surface roughness, texture, road geometry and rutting. Addressing the industry’s need for fast and precise testing, its vehicle mounted Pave Prof Profilometer performs in real-time and at highway speeds for millimetre accurate results; and to meet these challenging requirements PaveTest has chosen Riftek’s RF603HS series laser triangulation sensors - supplied and supported by Ixthus Instrumentation – for fast and highly accurate profile measurement. PaveTest prides itself on its flexibility for design and production with a capability that meets the needs of the global market it serves for transport authorities, paved surface constructors and operators, and many other organisations. With the PaveProf

specifications conforming to all the relevant ASTM standards, each system is typically customised to suit the exact nature of the test requirements where measured results can be interpreted to factors such as ride comfort, surface friction and surface noise generation. Furthermore measurement speed, road type, road width and vehicle mounting dimensions need to be taken into account. To address these many variables, the


exact number of triangulation sensors and their mounting arrangement can vary considerably from three or five sensor setups to multiple sensor assemblies. Typically mounted on the vehicle’s front bumper with a wheel mounted encoder tracking the precise vehicle speed and a high resolution accelerometer compensating for vehicle suspension movement, the PaveProf’s measured digital profile is
