Cat® SDX Screed Plate System

Overview

Designed to Increase Density and Smoothness

Cat® SDX Screed Plate Technology is designed to provide flexibility for highways, interstates, and commercial paving applications. The textured plates are designed to increase density and smoothness, while the smooth plates perform like traditional flat screed plate designs with the added benefit of modular, quick-change capability.

Benefits

Engineered for Paving Quality

The mixing action of the angular screed plates is designed to increase in-place density and provide better smoothness. In addition, firmer edge profiles improve joint matching capabilities. The smooth plates perform like traditional screed plates, with the added benefit of quick change capability.

Fabricated for Faster Changes

The modular plate design simplifies handling and the hardware-free fastening system enables the screed plates to be changed in as little as 4 hours after an initial aluminum adaptor plate install.

Designed for Longer Wear Life

Cat® SDX Screed Plates are designed with chromium-alloy materials that increase wear life when compared to traditional Cat Screed Plates. In addition, the modular plates allow opposite side interchangeability that can help maximize wear.

Features At A Glance

Compacting asphalt at its highest temperature helps maximize density and deliver smoother results
Kinetic mixing action created by the angular plates helps increase the bond interface between the asphalt binder and aggregate while promoting thermal uniformity for improved compaction characteristics
Increased in-place density can enable compaction to occur on a hotter surface shortening the compaction train
Higher stiffness values can lead to better longitudinal edge profiles and higher joint densities due to less lateral movement of the mix when being compacted

The angular surface provides a kneading action as mix passes through the diamond-shaped grooves and the tapering flat surface at the back of the plates provide a smooth finished surface
Confined mixing action manipulates aggregates to reduce air voids and increase density while creating a uniform surface texture
Optimized aggregate structure promotes surface temperature uniformity for consistent compaction
Enhanced structural integrity minimizes roller shoving for better smoothness
Increased stiffness strengthens unconfined edges, promotes better joint matching

Hardware-free screed plate installation saves time and effort
Tapered blocks integrated into the screed plates fit over the beveled edge of the adapter plates and are held in place with high-temperature silicone retainers that maintain tension for reliable performance
One-time adapter plate install attaches to the screed frame utilizing the existing screed plate orientation
Heating elements attach to the adapter plates
Modular screed plates come in 300 mm (12”) sections that weigh approximately 16 kg (35 lbs.). The plates are interchangeable across the screed width to help maximize wear.
The center screed section consists of 100 mm (4”) plates that weigh approximately 5 kg (12 lbs.). These narrow plates allow for crown at the center of the screed.

The system offers two extended-life plate designs that provide flexibility for highways, interstates, and commercial paving applications.
The textured plates are designed to increase density and smoothness, while the smooth plates perform like traditional flat screed plate designs with the added benefit of modular, quick-change capability.
In testing performed by Caterpillar utilizing ASTM G65 Dry Sand Rubber Wheel test procedures, the chromium-alloy material utilized in Cat SDX extended-life screed plates provided 4.2X more abrasion resistance when compared to the material utilized in standard-wear Cat screed plates. Note: 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.
