A milling machine from Roadtec has carried out important work at the National Centre for Asphalt Technology (NCAT) test track in the US. The 2.7km NCAT test track is used for asphalt pavement testing and research. As the facility is important to the advancement of asphalt technologies, Roadtec donates its time, equipment and personnel to carrying out rehabilitation work at the test track. An RX900E model was donated by Roadtec to NCAT and was used by David Bussard and Charlie Butler to mill to depths from 28.6mm to 1.07m. The machine had to mill the 8.5m-wide track in a number of passes and was fitted with a 2.2m- wide drum, featuring teeth on a 16mm spacing.
