Revolutionizing Paving: The New Cat® SDX Screed Plates
In the world of asphalt paving, precision and efficiency are everything. That’s why Caterpillar has introduced the Cat® SDX Screed Plate System—a game-changing innovation designed to deliver smoother surfaces, higher density, and faster service. Whether you’re paving highways, interstates, or commercial lots, the SDX system is engineered to elevate your results and reduce downtime.
What Makes SDX Screed Plates Different?
Traditional screed plates have long relied on flat surfaces to shape and smooth asphalt. The SDX system breaks that mold with a three-dimensional angular design that creates a kneading action as asphalt passes through diamond-shaped grooves. This mixing motion increases in-place density and reduces air voids, resulting in a more uniform and durable surface.
At the rear of the plate, a tapering flat surface finishes the mat with smoothness that rivals traditional designs—only now with the added benefit of enhanced compaction and edge integrity.
Performance That Pays Off
Contractors using SDX plates have reported up to 91% density directly behind the screed, reducing the need for multiple roller passes. In some cases, crews have been able to eliminate a compactor altogether, saving time and operating costs without sacrificing quality.
The system also improves joint matching and edge stiffness, which contributes to better International Roughness Index (IRI) scores and longer-lasting roads. For paving professionals, that means more consistent results—and more opportunities to earn performance bonuses.
Built for Efficiency and Longevity
The SDX Screed Plates are constructed from cast chromium-alloy, offering up to three times the wear life of conventional plates. Their modular design allows for quick-change capability, with hardware-free installation that can be completed in as little as four hours. That means less downtime and more productivity on the job site.
Each plate section is interchangeable across the screed width, promoting even wear and simplifying maintenance. The system also includes a one-time adapter plate installation that integrates seamlessly with existing SE60 V and SE60 V XW screeds.
