Paving quality – solid evidence
During a construction job in South Africa, it was scientifically proven by the University of Twente that the MT 3000-2 Offset PowerFeeder improves paving quality – among other things, using RoadScan, the innovative temperature measurement system from VÖGELE.

Organizing paving work so that it can proceed without interruption in order to enhance quality is one of the key reasons for using material feeders. And it‘s why in South Africa there is a strong focus on the decoupled transfer of mix from feed lorry to paver. Indeed, for major construction projects, SANRAL, the national roads agency, insists on the use of material feeders.
An advanced VÖGELE MT 3000-2 Offset PowerFeeder with a VÖGELE SUPER 1800-2 paver was used for the rehabilitation of a 4 km-long stretch of the N14 national route near Johannesburg by the South African construction company Power Construction (Pty) Ltd. On the job site, scientists from the University of Twente investigated whether the innovative VÖGELE material feeder improved the quality of the paved binder and surface courses.
One of the crucial factors was the temperature of the asphalt immediately after paving. The temperature was measured using two mutually independent systems, one of which was RoadScan, the non-contacting temperature-measurement system from VÖGELE. To provide a comparison, some sections were also completed without using a material feeder.
