Overview

Dynamic Material Flow, Easier Replacement, More Uptime

The Cat® SDX Screed Plate Technology is designed to help improve road quality with better consistency and higher reliability. This revolutionary design provides dynamic flow through the screed plates to reduce air voids and increase density.

Benefits

Better Quality

The mixing action of the angular screed plates is designed to help increase density and provide better smoothness. In addition, firmer edge profiles improve joint matching capabilities.

Faster Service

A hardware-free fastening system enables the screed plates to be changed in as little as 4 hours after an initial aluminum adaptor plate install.

Increased Longevity

The angular design of the SDX Screed Plates run flatter than traditional screed plate designs and can provide longer wear life. In addition, the modular plates allow opposite side interchangeability that can help maximize wear.

Features At A Glance

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

Kinetic mixing action helps increase the bond interface between the asphalt binder and aggregate
Mixing action of the angular plates is designed promote better thermal uniformity for improved compaction characteristics
Increased density can enable compaction to take place on a hotter surface shortening the compaction train
Increased stiffness can lead to better longitudinal edge profiles and higher joint densities due to less lateral movement of the mix when being compacted
Higher densities produced by the screed plates can lead to increased bonus opportunities

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.
