ABSTRACT
The temperature of a bituminous mixture during the paving process is a critical parameter for the compaction, and therefore the quality of an asphalt pavement. In order to register the asphalt temperature during road construction, paving machines can be equipped with thermal infrared line scanners. This paper describes the use of a commercially available thermal infrared line scanner during the construction of a bicycle path. The usability and accuracy of the system is assessed by means of other temperature measurement techniques. A probe thermometer is used to register asphalt temperatures in the truck, hopper and near the auger of the paver. Additional a thermal imaging camera is used to evaluate the line scanner readings. Useful information about the paving process is derived, such as cooling rates of the material during different steps in the paving process.
