Caterpillar updates Cat^® AP1000 and AP1055 pavers, introduces new smooth SDX plates and collision mitigation

LAS VEGAS, March 1, 2026 – Caterpillar announces multiple design enhancements for the Cat® AP1000 wheel and AP1055 track asphalt pavers, targeting increases in reliability and longevity as well as simplified maintenance. Plus, customers now have a choice between two innovative SDX Screed Plate System designs – original Textured SDX plates and new smooth SDX plates that perform like conventional screed plates with the added benefits of long life and quick-change capability.

The Cat SDX Screed Plate System can meet contractors’ biggest challenges by delivering the density and smoothness required for interstate paving with quick-change capability to be used on a wide range of applications from mainline to commercial. Two SDX plate designs are now available for contractors. Textured SDX plates feature angular grooves that promote increased density and smoothness behind the paver to help meet the toughest density specifications. Performing like traditional screed plates, smooth SDX plates deliver the added benefit of modular, quick-change capability.

Built with chromium alloy materials, Cat SDX plates deliver significantly more abrasion resistance than Cat standard and cladded extended-life screed plates.

Test results do not guarantee similar abrasion resistance improvements in paving application performance. Results may vary due to individual plate variation, paving techniques, and paving conditions.

Caterpillar’s unique SDX screed plates are designed with integrated tapered blocks that fit over the front and rear of the adaptor plates. High-temperature silicone locking bans apply tension to securely hold the screed plates in place. Reducing standard hardware needed, the design shortens replacement time to as little as four hours.

Enhancing situational awareness when operating the compactor, the now available Cat Detect – Collision Mitigation System features an integrated, intelligent sensor array to provide forward and reverse collision warnings, people detection, motion inhibit, and automatic braking. Visible in real-time and recorded for future analysis, critical zone detection events transmitted to VisionLink™ enables organizations to proactively mitigate potential hazards, enhance operational safety and identify opportunities for improvement.

The Collision Warning radar system targets collision potentials in front of and behind the compactor using audible and visual alerts that allow the operator to see, manage and mitigate hazards that may otherwise go undetected. Leveraging smart cameras, People Detection alerts the operator when on-site personnel are detected to the front and rear of the compactor, providing alert levels that dynamically adjust travel speed based on the person’s proximity to the machine.

With manual override capability, Motion Inhibit prevents compactor movement when the machine is stationary for at least two seconds and the detection system identifies a collision potential. When the compactor is in motion and critical zone detection occurs, Automatic Emergency Braking activates if the operator fails to act. When the critical zone detection clears, compactor control returns to the operator.
