VÖGELE RoadScan
Keeping an eye on quality with VÖGELE RoadScan
Making quality measurable is one of the big challenges facing contractors and clients worldwide. In road construction, it is particularly important to verify that a constant paving temperature has been maintained, as this is a key criterion for ensuring the quality and durability of roads. As a result, the significance of comprehensive temperature monitoring is currently on the rise in an increasing number of markets. With the non-contacting RoadScan temperature measurement system, VÖGELE provides an innovative and economical solution for the road construction sector.
The system helps paving teams monitor the temperature of the supplied mix continuously. On completion of the construction project, contractors also have detailed evidence that the work was carried out in the correct temperature range – thanks to recorded GPS data which include precise positioning information.
The heart of VÖGELE RoadScan is the high-precision infrared camera with 100% measurement coverage
It scans the whole of the asphalt pavement behind the screed. A highly accurate GPS receiver is also mounted in the housing for the infrared camera. This records the exact position of the temperature data. External parameters affecting paving are recorded in addition to position. A pyrometer mounted in front of the undercarriage measures the base temperature before paving. Along with asphalt temperature, a weather station can also document wind speed, wind direction, ambient temperature, air pressure and humidity.
The maximum measuring width of 10m is made up of 40 squares measuring 25 x 25cm. Each of these grid squares contains up to 16 individual measuring points from which a mean value is calculated. The measurable temperature range is between 0°C and 250°C, with a tolerance of just ±2°C.
Intuitive operation is a trademark of VÖGELE and is also a feature of the RoadScan system.
This already becomes evident during installation. Before use, the measuring unit is simply mounted on the roof of VÖGELE "Dash 3" pavers and requires no further adjustments. It is ready for operation as soon as it is connected.
The system is conveniently activated from the paver operator's ErgoPlus 3 console. The paver operator can read currently-recorded temperatures off the colour display, clearly visualized by means of thermal imaging. The images are transmitted in real time.
