A computerized paving system based on the use of a global navigation satellite system (GNSS) and zone laser technology. Based on 3D design data and position information received from GNSS, paving machines such as motor graders and asphalt pavers are automatically controlled with high accuracy.

This system uses an auto tracking total station to automatically control the height at which pavement is laid down and leveled by paver. As the control range is narrower than that of GNSS technology and the equipment is easy to set up, the system is suitable for rationalizing small- and medium-scale paving operations, reducing the need for skilled labor for such operations, and carrying out high-precision construction work.

This system automatically controls the pavement height on bridge deck slabs by using magnetic fields generated by weak electrical currents. With no need to install string lines to control an asphalt paver, it is possible to improve safety, carry out high-precision paving work, rationalize the work that is performed, and make labor-saving decisions.
