The Grade Control System offers distinct advantages to the engineer and/or contractor on any project requiring smooth, variable depth paving or milling. The unit adapts to any paver or planer that has electric/hydraulic control, eliminates string line setup to pave, allows asphalt to be placed accurately (+/- 3mm), increases productivity, and is far less costly to use versus conventional methods. To illustrate, survey data can be input into the Grade Control System for a 10,000 foot runway before 2 men can setup string line for paving over a 200 foot distance. The system is offered for sale or for lease, and includes training. Thicknesses are input to the system manually, or directly from either spreadsheet or from design via the Survey Profiler.
