Groundbreaking screed plate technology plus experience-inspired solutions combine for an industry shake-up. Meet the Cat® SDX Screed Plate System.
Since the arrival of the first pavers, screed plates have had flat surfaces. Now, the paving industry is about to see its most significant change in almost a century. Cat® Paving is introducing the Cat SDX Screed Plate System, a one-of-a-kind assembly of industry innovation only from Cat.
We’re going to break down exactly how Cat is laying the groundwork for a paving evolution.
The seamless integration of the Cat SDX Screed Plate System’s dual-patented design and trade-inspired construction have led to a screed plate system with a dynamic series of value points for major paving jobs in a variety of conditions. From performance, to longevity, to serviceability, let’s take a closer look at the components that make this possible:
- Adaptor Plate Cat SDX brings the heat with an insulated aluminum adaptor plate that retains the heating element. It attaches to the screed frame utilizing its existing structure for retrofit to the SE60 V and SE60 V XW screeds.
- Screed Plates Cat SDX makes a mark with a three-dimensional screed plate surface design that allows it to generate a stiffer mat. The main and extender sections are comprised of multiple plates, all casts made of high-strength chromium carbide.
- Fastening System Cat SDX brings it all together with a revolutionary locking system that eliminates the hardware. Tapered blocks integrated into screed plates correspond to the adaptor plate’s custom beveled edges. High-temp silicone retainers maintain the tension.
The Cat SDX’s one-time adaptor plate installation requirement simplifies maintenance, and the patented fastening system reduces plate replacement time. On top of that, the unique plate design encourages more uniform wear, that can extend plate life when compared to conventional screed plates.
How The Cat SDX Screed Plate System Builds Better Roads
When pursuing the incredibly high standards of road building specs, paving continually comes back to two qualities in the mat: density and smoothness. Asphalt compaction at its highest temperatures means maximized density, potentially smoother mats and a requisite reduction in air voids to meet necessary targets.
The Cat SDX system creates a kneading action and dynamic material flow that enhances compaction and increases density, leading to a number of improved outcomes; contractors have experienced reduced IRI scores and better edge profiles. Kinetic mixing action generated by the angular plates create consistency across the width of the mat to help lower standard deviations between density readings and help meet Percent Within Limits (PWL) specifications.
This increased density and improved compaction create a surface visibly different, even to an untrained eye. Unconfined joints express little lateral movement. The mat doesn’t get pushed or shoved around on a first pass. Even boot prints don’t leave an indentation. What’s more, these resulting effects are all achieved at the critical juncture in the paving train: when the asphalt mix is getting placed under the screed itself. What you get is better surface uniformity for a stiffer, denser and smoother mat.
To hear insiders say it, the Cat SDX Screed Plate System provides product solutions that directly address issues the industry has faced for years. Paving might never be the same.
