GOMACO to debut two new machines at CONEXPO-CON/AGG 2026

The new Polymer Paver and GP348 placer/spreader slipform paver will be part of GOMACO's CONEXPO-CON/AGG 2026 display of 13 pieces of equipment showcasing the company's full line of concrete paving and support solutions. 

Highlights of GOMACO's new Polymer Paver

The Polymer Paver can pave overlays on bridge decks and flat slabs in widths from 6 to 30 feet (1.8 to 9.1 m). The all-welded steel frame sections feature bolted connections, allowing easy width changes. The welded polymer paving pan sections are available in widths to match the frame sections. Vibration is provided by sectional rotary eccentrics supported by ball bearings. The vibration is coordinated to start and stop with the machine movement. A dual-drive 9-inch (229 mm) variable speed auger spreads the material ahead of the paving pan.

The Polymer Paver is powered by a 74-hp (52 kW) diesel engine, which does not require diesel exhaust fluid. Four tracks allow for easy operation and loading/unloading. A four-bogie option allows for paving up against a barrier wall. 

The Polymer Paver features GOMACO's G+ control system for grade and steering. A 10-inch (254 mm) full-colour display provides the operator with control over all paving machine functions. The control system is multi-lingual and can toggle between metric and imperial settings. The tethered control display is magnetically mounted and can be positioned where the operator prefers for optimal operator visibility.

GOMACO introduces its first four-track placer/spreader slipform paver

With the new GP348, GOMACO is building on the success of the GP360 and GP460, the industry's first combination concrete slipform pavers and placer/spreaders on two tracks. The GP348 is a four-track machine that adds extra mobility. As a placer/spreader with a 48-inch (1,219 mm) belt, the GP348 will place at widths up to 36 feet (11 m) wide. As a concrete slipform paver, the GP348 will pave widths up to 30 feet (9.1 m) wide. 

It's built on the framework of the GOMACO four-track GP3 slipform paver with the ability to convert the prime mover into a concrete placer/spreader. The prime mover is equipped with vibrator circuits for paving and auger drive circuits for placing. Controlling the new technology is made possible with the GOMACO-exclusive G+ digital control system. G+ seamlessly handles the controls conversion needed for each application while also bringing on board Machine-to-Machine (M2M) communication, sonic sensors, 3D machine guidance, and more. Rotary-sensored slew drives on its leg pivots work seamlessly with the G+ control system.

Operators can automate transitions from transport to paving mode, dramatically reducing setup time and improving efficiency. Its four-track design enhances stability and on-site manoeuvrability, while its compact transport footprint allows it the capability to be hauled on a single semi-tractor trailer (either as a placer or paver), minimizing downtime between pours.

The GOMACO GP348 is powered by a Caterpillar C7.1 turbocharged diesel engine. The high-volume, 48-inch (1,219 mm) conveyor belt can be mounted on either the left or right side, depending on job site conditions and the location of the haul road. It has a discharge speed of up to 491.5 feet per minute (150 mpm) for fast and efficient concrete placement. A controllable material deflector directs the flow of concrete at the discharge end of the conveyor for placement accuracy. A dual-drive auger system moves the material to the centre or outer areas and across the strike-off. 

The GP348 is available with an optional sonic sensor system to monitor the concrete depth as it is placed. Information from the sonic sensors is utilized by the G+ control system on the paver using M2M communication to provide an optimum and consistent head of concrete in front of the paver.

GOMACO can be found at booth C30282 in the Central Hall.
