Astec Industries started a refresh of its Roadtec pavers in 2023 with the introduction of two updated machines, the 8-foot RP-175 and 10-foot RP-195 F-series. The overall look of these tracked highway-class pavers has been updated, and design changes emphasize uptime and operator safety.
Astec recognized several areas where the highway-class machines could be modernized and strengthened, according to Keith Hagy, product manager, Paving – Infrastructure Solutions. The overall look of the pavers became a starting point.
“Historically, we have focused much more on optimizing the function of the machine over design – we haven’t really changed the look for many years,” Hagy says. “The first thing you’ll notice with our F-series pavers is more of a streamlined look when you see the side profile of the machine.”
Design change adds undercarriage reliability and easier maintenance access
Astec identified design opportunities in the undercarriage that would improve reliability and reduce customer downtime. The undercarriage, initially designed as a multi-piece weldment, has undergone a transformative shift to a two-piece solid casting track frame, greatly streamlining the production process while strengthening the overall durability of the F-series.
This approach significantly minimizes weld points throughout the machine. “The result is a streamlined undercarriage structure that greatly reduces maintenance requirements, ensuring more reliable and efficient operation for our customers,” Hagy says.
It also adds commonality between the 8-foot and 10-foot platforms, providing further production and service efficiencies across the F-Series platforms.
The new body design is not just an aesthetic update, but also reduces weight and gives users better access to key components. Composite materials are used for the hood and side panels, so operators will no longer need a hydraulic pump and lifts to raise the hood. This makes it easier for operators to check fluid levels daily, while side panels can be easily opened to access service points and filters.
Greater visibility is incorporated into the new design. Operators can see straight to the front of the hopper and with swing-out seats can gain a full view of the screed and head of material in the auger. Brightly coloured handrails and stairways help users quickly recognize where the safe access points are on the machine.
Both pavers have been updated to full Stage V / Tier 4 Final Cummins engines. The RP-175 is fitted with a new four-cylinder engine as opposed to the previous six-cylinder unit, a move that Hagy expects will provide higher fuel efficiency.
