imaging has been encouraged by researchers as a good quality control device to measure pavement uniformity [48].

Many Departments of Transportation (DOTs) have used a Paver Mounted Thermal Profiler (PMTP) from MOBA: Mobile Automation, initially developed with the Texas Department of Transportation and Texas Transportation Institute. This company has two systems that provide the full coverage thermal profile: the sensor beam and the Pave IR ScanTM, both shown in Figure 9. The sensor beam consists of 12 infrared sensors connected to a central MOBA OperandTM [26]. A GPS antenna is mounted above the computer to track location. The entire system can be powered by the paver if it is a permitted installation or by generator. The device is designed for easy set up and storage so that it can be moved from one machine to another quickly. The infrared sensors attached to the beam scan the area directly below the device and is compiled by the computer to output a complete thermal profile to the operator or inspector. The second, newer device is the Pave IR ScanTM. This device is attached to a mast along with the GPS and weather station and is connected to an on-board computer [52]. This device is can also be powered by the paver or generator and can easily be moved to another machine. The PMTP scans back and forth across the pavement to collect thermal data where is it
