Precise 3D paving boosts safety at transport terminal
Usually asphalt is paved with ride-ability in mind but not at the NSW Ports’ Intermodal Logistics Centre at Enfield in South-West Sydney. It requires one of the world’s most level surfaces. Bumps, uneven grades or accumulated water can be hazardous to the wheeled cranes that carry 90 metric ton loads, high and heavy, across the surface.
This leads to some very tight tolerances during the paving of the centre, particularly its Intermodal rail (Terminal) section, where the heavy loads are transferred for distribution.
The desired paving tolerances had average conformance of 0 millimetres and standard deviation of 4 millimetres across an area of 92 000 square meters.
When asked to investigate new technologies that might be able to meet the desired tolerances Boral conducted a thorough evaluation of 3D paving solutions. Ultimately Trimble 3D Paving Control System was selected.
See the case study on the Trimble site to see how Boral was able to meet the tight tolerances.
