The road surface profiler’s optical components can produce large projection points and the internal sampling rate can be several times higher than the output. The polygon mirror on the road surface profiler allows the projection point to sweep across the width of the road. Another advantage is that the projection point in the scan direction is effectively widened.
The asphalt binder tester consists essentially of a high precision apparatus combining an ignition oven to a continuous weighing system to monitor the loss of weight of the asphalt sample and to automatically determine, at the end of the test, the binder content and percentage. An independently controlled auxiliary afterburner chamber significantly reduces the furnace emissions. The asphalt binder tester is supplied complete with double sample basket/safety cover, extraction fork and 3 meters of metal exhaust pipe.
The road surface profiler is a pavement sensor developed with the latest professional technology. Safer to use, economical and practical, easy to install on any vehicle worldwide are its advantages. The road surface profiler was originally developed for PSI. The road surface profiler has a 90-degree Angle of view and can scan a 4.3-meter range at a speed of 1,000 times per second, as long as it is mounted on a test vehicle with a road surface of 2.15 meters or more.
There is no doubt that road profilers can play a big role in road safety, but do you know which stage of the road profiler technology is now in progress? How should I choose a road surface profiler?
The Falling Weight Deflectormeter (FWD) came into being in the early 1970s. It is a pulsed dynamic sinuometer. It simulates the instantaneous impact of automobile load on the road surface and obtains the instantaneous deformation of the road surface. Its measurement results are more accurate, and the information is large.
