Using robotic total stations and Millimeter GPS, Topcon’s ZS100 combines two existing technologies to give operators fewer set-ups, fewer instruments – and a much simpler job site
A $16 million runway project at Cotonou Cadjehoun Airport needed Topcon Positioning’s RD-M1 road scanner to ensure precise milling and quality resurfacing.
Tough competition is being seen in the specialised market for concrete slipforming machines, with new partnerships and new technology coming to market - Mike Woof writes
GOMACO is boosting the versatility of its Commander slipformer further with the development of the new Three-Track Commander IIIx variant. This has been configured to cope with much tighter radii than previous versions of the Commander III, allowing it to slipform a radius of just 610mm. This suits the machine to applications such as sli
Milling and paving repair operations for airport runways require particularly high tolerances, an obvious market for 3D control solutions writes Mike Woof. Airport runways require some of the most accurate quality standards and tightest tolerances of any asphalt or concrete surface. This is one area where the high precision capabilities of 3D systems offer clear advantages.
The use of GPS machine control on sub-base has improved final rideability on a major highway reconstruction project. Innovative construction techniques have helped to upgrade a 9.6km stretch of the 307km long I-96 highway in the US state of Michigan. The Michigan Department of Transportation (MDOT) project was initiated in the third quarter of 2009 and was completed in the fourth quarter of 2010. Interstate Highway Construction acted as general contractor on the project, which included widening the shoulder
