Round-the-clock consistency

Belgium civil engineering and building company Betonac, has been using Leica's PaveSmart LMGS-S 3D machine control system on two slip-form concrete pavers in runway and motorway construction.

The PaveSmart systems have been used on a Gomaco GP2800 and a Gomaco Commander II – since April 2003 on highway projects including the E40 (A10), between Brussels and Ostend, and the E411 and E25 in Luxembourg, as well as the Charles de Gaulle (Paris), Bierset (Liege) and South Charleroi (Brussels) airports.

The two total stations and various inclination sensors control the line and level of the concrete paver.

A spokesman for Leica said, “There is no longer a need for tension wire control systems on either side of the machine and total station positioning allows the system to directly control the paver in the 3D ground model of the road or any other surface.

The system can be used for every conceivable arrangement of equipment and across the whole spectrum of slip-forming applications.”

Chief engineer, for Betonac, Ludo Philtjens, said, it is possible to operate non-stop for 24 hours and thus dispense with the need for end-of-day joints.

“Adjustments to line and level are possible at any time. The system displays the actual construction tolerances and therefore provides another excellent means of extended quality control,” he said.
