Topcon Positioning Systems’ (TPS) P-32 asphalt paving control system features the GC-35 full-color, graphical display control box. The new system also includes Topcon’s Sonic Tracker, slope sensor and is fully compatible with its Smoothtrac sonic averaging system.

The P-32 system is designed to allow for control of both sides of the paver by one operator.

“The operator can view elevation and slope values of the screed from a single box, a time-saving feature made possible by refining existing, time-tested machine control technologies from Topcon and combining them with the new GC-35 control box,” said Tony Vanneman, TPS construction product marketing manager.

The GC-35 box has a 3.5 in., full-color LED display designed for use in bright or low light, making it easy to read during paving projects, day or night.

“With large graphics and text, an easy-to-navigate menu, a configurable display layout and an incredibly fast processor, the operator can quickly determine options and make selections to create smooth and accurate cross-slope transitions and improve overall paving control,” Vanneman said.

Water- and dustproof with an IP67 rating, the new GC-35 box is built to handle harsh conditions encountered in the field. In addition to its durability, it’s designed to stay up-to-date with firmware updates made quickly and easily through a USB connection. It also is backward compatible to Topcon System 5 paving control systems.

“All aspects of the P-32 design are meant to be long-lasting with improved performance for the operator such as the positioning of the cables — mounted on the side of the box instead of below the box to keep the cables out of the moving parts of the paver,” Vanneman said. “With its overall operator interface and its rugged exterior, the system is built job site-ready for the toughest challenges of asphalt paving.”
