Road profiling systems available from Bestech Australia are designed to collect continuous high-speed measurements of longitudinal profiles of road surfaces in real-time.
Surface profiling is a critical aspect of road and pavement engineering that helps to calculate roughness and ride comfort. Road profiling systems utilise non-contact laser sensors to measure the distance to the road surface as well as accelerometers to compensate for the effects of the vehicle’s movement.
An important exercise for road builders, contractors and even governments, road profiling gathers information such as longitudinal profile, micro and macro textures, and roughness to determine coefficients of friction.
Road profile measurements are also difficult to execute due to the dynamically changing targets, including tarmac, concrete and paint.
Acuity’s AR700 road profiling systems, available from Bestech Australia incorporate optics, electronics and signal processing algorithms specifically developed for road profiling.
The AR700 is a triangulation sensor that measures distance by projecting a beam of laser light to create a spot on a target surface. Reflected light from the surface is detected on an angle from inside the sensor, and the distance is processed by a microprocessor.
Key features of AR700 road profiling systems:
- Sensor optimised for road profiling
- 9.4 kHz sampling speed and low-noise digital output makes it the standard for road profiling applications
- Accounts for different surface types, vehicle speeds, vibration, sunlight and temperature conditions
- Measuring ranges are 3.175 to 300mm, and linearity is ±0.05% of the range
- Resolution is down to 0.005% of the range
- Laser spot diameters as little as 30µm
