Cat® SDX Screed Plates
- The optional Cat® SDX Screed Plate Technology helps 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.
- The screed plate design consists of an angular surface on the front of the plates with a tapering smooth surface near the back. A kneading action occurs as the plates manipulate the mix as it passes through the angular grooves.
- The innovative design enhances the structural integrity of the asphalt, lessens compactor shoving, strengthens unconfined edges, and promotes better surface temperature uniformity.
Application Versatility
- Common applications include large parking lots, highways, intersates, airports and many other high production pay for performance applications
- The standard paving range of 3 m - 6 m (9' 10" - 19' 6") provides excellent performance when changing paving widths for both urban and highway paving applications
- Simple, bolt-on extensions offer a maximum paving width of 7.45 m (24' 5")
Simple Operation
- Operating displays can be tailored to specific language requirements with multiple options available
- Exclusive 2-speed, proportional extender control provides smooth adjustment when transitioning paving widths
- Screed operating consoles are equipped with ratio adjustment for the augers and conveyors, providing the ability to modify material flow
- Power controls for extender slope and height enables operators to quickly manage mat angles and surface textures
- Trailing edge screed plate adjusters help maintain an even plane across the width of the screed in order to enhance paving quality and extend screed plate life
Smooth Material Flow
- Screed plate depths of 407 mm (16") on both the main and extenders provide stability and good mat textures
- The heated end gate option helps prevent material from sticking for better edge profiles and joint matching capability
Pave Start Assistant
- Pave Start Assistant saves set-up profiles for repeatable use on future job sites, simply activate the profile for quick, single person setup
- Set-up preferences include: tow-point height, screed heat temperature, paving speed, paving width, paving depth, crown, extender slope and height, screed assist, and screed locking features
- Setup features are located in the left screed display and can also be viewed through the tractor displays
Quick Heat, Even Distribution
- The tractor-integrated generator delivers 15 minute heat-up to 130º C (266º F) for quick starts
- Electric heating system with zone monitoring helps ensure even heat distribution and smooth asphalt textures while also allowing heating to continue in the event of a temperature sensor failure
Pendent Control (Option)
- Manual overrides and pause function capability for each auger and each conveyor are available to match changes in material flow requirements
- Power slope and height functions assist with profile
- Automatic Grade Control activation provides flexibility when working on the outer edge of the screed
Cat® Grade Control (Option)
- Factory-integrated leveling system that helps remove irregularities from the surface and control mat thickness for increased production, lower operating costs, and higher profitability
- User-friendly system with text-based displays, split screen-mode, and on-the-go sensor selection
- Precise control driven by 10-point auto-calibration, true averaging with 5 transducers in each sonic sensor, and cross coupling feature that maintains slope requirements more consistently when changing elevation
