Screed Plates

Screed plates deliver a high-quality mat and a long service life. Screed plates are constructed of abrasion resistant alloy steel that resists damage and provides an enhanced service life.

Abrasion Resistant Alloy Steel

Screed plates are constructed of abrasion resistant alloy steel that resists damage and provides an enhanced service life.

Precompaction And Material Flow

Curved nose bar design provides precompaction and enhances material flow under the screed.

Nose Bar And Screed Plate Replacements

Nose bar and screed plate replacement are simplified with tapped holes and studs.

Heavy-Duty Mounting Platform

Heavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling.

Screed Plate Leveling

The screed plate leveling system incorporates a threaded bolt design that provides quick adjustment.

Quick And Convenient

Screed plate leveling is quick and convenient with the trailing edge adjusting system.

Trailing Edge Adjusting System

The trailing edge adjusting system saves time when installing new screed plates or when adjusting existing plates.

Extra Corrosion Resistance

The trailing edge adjusting bolt system hardware is plated to provide extra corrosion resistance.

End Gates

The spring-loaded end gates create a downward force to help contain the asphalt and follow the profile of the surface being paved.

Spring-Loaded End Gates

Spring-loaded end gates create a downward force that causes the gates to follow the profile of the surface being paved, assuring a good joint with the adjacent mat.

False-Wall Design

False-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.

Bolt-On Design

Bolt-on design allows easy end gate installation and removal.

Replaceable Wear Strip

Replaceable wear strip enhances end gate service life.

Full-Length End Gate

Full-length end gate contains material, providing an optimal longitudinal joint.

Triangular Extender Configuration

Each extender is supported by two extendible support tubes and a third frame member to form a triangular configuration that provides torsional resistance and rigidity.

Support Provided For Each Extender

Two extendable support tubes and a third frame member provide support for each extender.

Visual Graduated Scales

Visual graduated scales indicate the distance that the extenders move in or out.

Hydraulically Driven Vibrators

Hydraulically driven vibrators located on the extenders are synchronized with the main screed to match frequency and amplitude.

Vertical Height Adjustment

Vertical height adjustment allows the extenders to match the main screed height.

Adjustable Plate

An adjustable plate on the inboard side of each extender provides a tight joint in order to prevent asphalt from bleeding between the main screed and the extender.

Diesel Screed Plate Heating System

The Extend-A-Mat 10-20B offers a diesel screed plate heating system. The diesel screed plate heating system is highly efficient and provides fast warm-up. The diesel heating system features four burners and glow plug ignition.

Four Diesel Fuel Burners

Four diesel fuel burners, two on the main screed and one on each extender, provide fast screed plate heating.

Even Heat Distribution

Burners on main screed and extenders are mounted on a replaceable, baffled combustion chamber with flame deflectors that direct heat to screed plates, providing even heat distribution.

Full-Length Insulation

Full-length insulation over the combustion chamber enhances heating efficiency and minimizes heat transfer to the screed frame.

Glow Plug Ignition

Glow plug ignition is actuated from the main screed control boxes.

Built-In Timer

A built-in timer allows 15 minutes of screed plate heating, preventing overheating of the plates.

Electric Screed Plate Heating System

The Extend-A-Mat 10-20B offers an electric screed plate heating system. The electric screed plate heating system is highly efficient and provides fast warm-up. The electric heating system features an integrated generator and multi-zone heating elements for even heat distribution.

Heating Elements

Heating elements provide a warm-up time to 122° C (220° F) in 30 minutes or less when ambient temperatures are 22° C (40° F) and above.

Multi-Zone Heating Element

Multi-zone heating element configuration provides even heat distribution.

Screed Control Panel

Screed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt and extended temperature based mixes.

Regulated Screed Plate Temperature

Controller automatically regulates the screed plate temperature to the selected setting.

Minimal Operator Training

On-board diagnostics and screed control panel require minimal operator training.

Generator System Tractor Option

The generator system supplies power to the optional electric screed heat and to the optional auxiliary power supply panel.

Industrial, Single-Phase Generator

Industrial, single-phase generator operates at 1800 rpm, includes GFCI breaker protection and provides low sound levels.

Single Control Switch

Single control switch located on the tractors operating console activates the generator.

Full Power

Full power is provided to the electric screed and the optional auxiliary power panel while the engine is operating at idle speed.

Dual Bearings

Dual bearings with seals extend service life and internal electronic voltage regulation provides consistent power.

Auxiliary Power Panel (Tractor Option)

The optional auxiliary power panel supplies 8 kW of power for night-time lighting and job-site work tools. The panel includes four 120-volt receptacles and two 240-volt receptacles.

Auxiliary Power Panel

Optional auxiliary power panel provides 8 kW of power and includes four 120-volt and two 240-volt receptacles.

Ground Fault Circuit Interruption

The 20-amp receptacles are circuit breaker protected with ground fault circuit interruption (GFCI).

Auxiliary Power Panel Door

Auxiliary power panel door can remain closed while power cords are attached to the receptacles providing protection.

Serviceability

Extend-A Mat screeds are easy and fast to service. This screed has been designed for easy service and maintenance with special emphasis given to component access.

Easy Service And Maintenance

This screed has been designed for easy service and maintenance with special emphasis given to component access.

Hydraulic Hoses And Electrical Wiring

Hydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service.

Diesel Fuel Burner Lines

Diesel fuel burner lines are equipped with a quick-disconnect coupling that simplifies switching from the screed plate heating system to the wash-down system.

Remote-Mounted Fittings

Remote-mounted fittings for vibrator bearings provide simplified lubrication access.

Hydraulic Leaks

O-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks.
