Recon’s automated machine level systems provide survey accurate, variable depth, asphalt paving and milling level control. Used on a range of high profile projects throughout Australia, New Zealand and the Asia Pacific region the system can be fitted to any asphalt paver or milling machine to control levels to survey accurate, millimetre tolerances. This ensures compliance with the most stringent contractual specifications whilst allowing for the effects of differential asphalt compaction.
The levelling system uses a process of an initial Robotic Total Station survey to determine the precise asphalt paving or milling depths for each consecutive running lane the machine is required to operate on. This results in the creation of a paving or milling survey grid table. This survey grid table is then uploaded to the grade control system.
As the paver or milling machine travels along eachpreviously surveyed running lane the leveling system automatically controls the hydraulics of your paver or milling machine to achieve the desired survey levels with millimetre accuracy and even accounts for the effects of differential compaction. Recon's technician monitors the system and performs real time quality analysis. A subsequent survey is undertaken providing the contractor with full conformance reporting.
We understand our clients are only interested in absolute perfection. As a result we’re used to chasing millimetres under pressure. Our 2D and 3D paving and milling control solutions have been designed to ensure the best results possible in many different environments.
When you’re chasing plus or minus 5mm across a broad reach of pavement, the process becomes as much art as science. Our team numbers several survey parties working across New Zealand and Australia 24/7 and through collaboration with our clients, they ensure milling and paving depths are consistently achieved to criteria.
New Zealand Steel has been utilising Recon’s Unmanned Aerial Vehicle (UAV) mapping technology to accurately measure stockpile volumes on a regular basis at its Waikato North Head mine site. The technology has resulted in faster data acquisition turn-around times, as well as the elimination of survey staff from within potentially hazardous environments at the mines.
