Vogele Innovates with RoadScan Temperature Measurement System

Contractors can keep an eye on quality with the RoadScan from Vogele, a Wirtgen Group company, Antioch, Tennessee. The RoadScan non-contacting temperature measurement system is an innovative and economic solution for verifying constant paving temperatures.

The RoadScan device scans the whole of the asphalt pavement behind the screed. A GPS receiver is also mounted in the housing for the infrared camera, which records the exact position of the temperature data. External parameters that might affect paving are recorded, in addition to position.

A pyrometer mounted in front of the undercarriage measures the base temperature before paving. Along with the asphalt temperature, a weather station can also document wind speed, wind direction, ambient temperature, air pressure and humidity.

The maximum measuring width of 10 meters is made up of 40 squares measuring 25 by 25 centimeters. 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 and 250 degrees C, with a tolerance of +/- 2 degrees C.
