Company Kutter used a Trimble 3D Paving Control technology to resurface the north take-off and landing strip, and a number of taxiways of the Leipzig/Halle Airport (LEJ). In total, the 3.8km long, 60m wide north runway and associated taxiways, approximately 300,000 square meters of concrete surfaces, needed to be replaced. In order to preserve the cement treated base course (CTB), the owner stipulated that the removal of the concrete surface needed to be vibration-free. In addition, the new concrete covering will be installed directly onto the milled surface so the elevation needed to be kept within 10mm. With the Trimble system an elevation accuracy of +/- 3 mm could be achieved over the entire area.
