The company used their GOMACO placer/spreader for accurate placing and spreading of concrete in front of the GP-4000 paver, and following the paver was the GOMACO T/C-600, used for texturing and curing the slab. The versatile GP-4000 has a telescoping modular frame. Depending on the paving width, various vibrator packages provide from 16 to 48 vibrator circuits.
