AS2301

The AS2301 is a production-sized screed. It is a hydraulically extendible screed that features front-mounted extenders. The AS2301 is well suited to all geographic areas. It is ideal for both new construction and overlay work. Common applications include industrial sites, large parking lots, urban and rural roads, subdivision streets, highways, interstates, airports and projects that require variable-width paving.

Screed Plates



Screed plates deliver a highquality mat and a long service life.

Resistant Alloy Steel



Screed plates are constructed of abrasion resistant alloy steel that resists damage and provides an enhanced service life. Quick screed replacement reduces maintenance downtime.

Precompaction And Material Flow



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

Curved Nose Bar



Curved nose bar is incorporated in the screed plate design.

HeavyDuty Mounting Platform



Heavyduty mounting platforms provide rigid support for screed plates, which simplifies leveling.

Screed Plate Leveling



Save time with the trailing edge screed plate leveling system.

Screed Plate Leveling Has Many Advantages



Screed plate leveling is quick, convenient and eliminates shims 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.

Plated Hardware



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

End Gates



Easytoadjust end gates ensure a good joint with the adjacent mat.

SpringLoaded End Gates



Springloaded 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.

FalseWall Design



Falsewall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.

BoltOn Design



Bolton design allows easy end gate installation and removal.

Replaceable Wear Strip



Replaceable wear strip enhances end gate service life.

FullLength End Gate



Fulllength end gate contains material, providing an optimal longitudinal joint.

Patented PreStrikeoff Shields



A pair of prestrikeoff shields are positioned at the front of the screed, making first contact with the mix after it passes through the augers.

Smooth Mat Texture And Prevents Segregation



Prestrikeoff shields allow the proper amount of material to enter the area in front of the main screed, which leads to a smooth mat texture and helps prevent segregation.

Adjustment Handles



Two adjustment handles allow the shield height to be fine tuned, depending on the mix or operating conditions.

Automatic Adjustment



When the thickness screws are used to adjust mat depth, the prestrikeoff shields follow the leading edge of the main screed, providing automatic adjustment.

Diesel Screed Plate Heating System



Highly efficient burner system provides fast, even screed plate heating.

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.

FullLength Insulation



Fulllength 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.

BuiltIn Timer



A builtin timer allows 15 minutes of screed plate heating, preventing overheating of the plates.

Electric Screed Plate Heating System



Highly efficient electric heating system provides warmup time in 30 minutes or less.

Heating Elements



Heating elements provide a warmup time to 122 C 220 F in 30 minutes or less when ambient temperatures are 22 C 40 F and above.

Even Heat Distribution



Multizone 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 HMA and extended temperature based mixes.

Regulated Screed Plate Temperature



Controller automatically regulates screed plate temperature to the selected setting.

Minimal Operator Training



Onboard diagnostics and screed control panel require minimal operator training.

Generator System 40Tractor Option41



Continuousduty integrated design ensures peak performance and high reliability.

Industrial, SinglePhase Generator



Industrial, singlephase 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 auxiliary power panel provides efficient power for nighttime lighting and other jobsite power needs.

Auxiliary Power Panel



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

Ground Fault Circuit Interruption



The 20amp 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



The AS2301 Screed is easy and fast to service.

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 quickdisconnect coupling that simplifies switching from the screed plate heating system to the washdown system.

RemoteMounted Fittings



Remotemounted fittings for vibrator bearings provide simplified lubrication access.

Hydraulic Leaks



ORing face seal fittings and couplings provide maximum protection against hydraulic leaks.

Nylon Sleeve Protection



Exposed hoses have nylon sleeve protection to reduce abrasion.

Vibrator System Hydraulic Lines



Vibrator system hydraulic lines are constructed of steel tubing, providing durability and resistance to damage.

HighQuality Components



Integrity of the electrical system is ensured with the use of highquality components.

Electrical Standards
