The industry standard Screed Control for asphalt pavers just got even better!

P-32 Benefits


  • Control both sides of the screed from either GC-35 Control Box
  • Digital LCD display provides clear 3-color grade and function icons
  • Rugged, field proven system and component reliability for over 25 years
  • Works with most full size asphalt pavers


Topcon, innovator of the world’s most widely used asphalt paver screed control introduces the next generation of 2D screed control, the P-32 Paver System.


Topcon’s P-32 Paver System builds on our industry-standard Paver System 5 featuring innovations that improve smoothness, assures accurate slope and material thickness and provides unmatched operator convenience and ease-of-use. To create this next generation system we started with the control box, the screed man’s interface to P-32. The all-new GC-35 Control Box features a large (3.5”), high-contrast, backlit display clearly letting the screed man know what’s going on at a glance, on both sides of the screed if desired. The superior graphics also makes machine setup and calibration a snap. GC-35 buttons are large, sturdy and environmentally sealed. And of course, it’s completely compatible with your existing System Five sensors and Smoothtrac® sonic averaging ski.


Ruggedized cables with weather protected connectors, super-accurate 100% slope capable Slope Sensor, Topcon’s patented Sonic Tracker II’s, and an optional Laser Trackerjack laser receiver demonstrates Topcon’s commitment to it’s continued leadership in asphalt paver screed control today and tomorrow.


The GC-35 box may also be purchased separately for System Five upgrades.
