b'COVER STORYThe cutting-edge 3D milling technology allows for variable milling depth on a road, resulting in perfect smoothness.usessatelliteGPSandnewlysurveyedgroundcontroland optimal depth, less material is needed to complete the points along the road to locate and record directional datajob. When you begin your milling with that highly accurate points along its surface (e.g., elevation, longitude, latitude,survey, you can usually save 20 to 40per cent material on distance from the pavement, etc.). These data points areanyprojectbecauseyourechangingthemillingdepth then fed into a Point Cloud model and used to create a 3Dto get the optimal smoothness, says Vitek Obr, CTO of model of the roads existing surface to an elevation accuracyControl Systems CA and European Exact Control System, tolerance of 2-3mm.
