3D Grade Control Systems Provide Precision & Savings

This article uses the case study of the National Corvette Museum (NCM) asphalt automotive test track to discuss the use of 3D grade control systems for asphalt paving. The NCM test track followed paving specifications that restricted surface deviations to only 1/8 inch (3 millimeters). The project used 3D grade and slope control systems to construct the earthworks and lay down the asphalt mix. The author describes the 3D grade control (also called Automated Machine Guidance or AMG) system; the use of computers on the milling machines and pavers; a department of transportation (DOT) case study in Florida that used 3D grade control systems in a project widening of State Route 417; and cost-effectiveness concerns regarding infrastructure, equipment, and crew training.
