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.
|Maximum Paving Width||7.32 m|
|Standard Paving Width||3.05 m|
|Minimum Paving Width||2.44 m|
Screed PlatesScreed plates deliver a high-quality mat and a long service life.
Resistant Alloy SteelScreed 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 FlowCurved nose bar design provides precompaction and enhances material flow under the screed.
Curved Nose BarCurved nose bar is incorporated in the screed plate design.
Heavy-Duty Mounting PlatformHeavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling.
Screed Plate LevelingSaves time with the trailing edge screed plate leveling system.
Screed Plate Leveling Has Many AdvantagesScreed plate leveling is quick, convenient and eliminates shims with the trailing edge adjusting system.
Trailing Edge Adjusting SystemThe trailing edge adjusting system saves time when installing new screed plates or when adjusting existing plates.
Plated HardwareThe trailing edge adjusting system includes plated hardware to provide extra corrosion resistance.
End GatesEasy-to-adjust end gates ensure a good joint with the adjacent mat.
Spring-Loaded End GatesSpring-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 DesignFalse-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.
Bolt-On DesignBolt-on design allows easy end gate installation and removal.
Replaceable Wear StripReplaceable wear strip enhances end gate service life.
Full-Length End GateFull-length end gate contains material, providing an optimal longitudinal joint.
Patented Pre-Strikeoff ShieldsA pair of pre-strikeoff 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 SegregationPre-strikeoff 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 HandlesTwo adjustment handles allow the shield height to be fine tuned, depending on the mix or operating conditions.
Automatic AdjustmentWhen the thickness screws are used to adjust mat depth, the pre-strikeoff shields follow the leading edge of the main screed, providing automatic adjustment.
Diesel Screed Plate Heating SystemHighly efficient burner system provides fast, even screed plate heating.
Four Diesel Fuel BurnersFour diesel fuel burners, two on the main screed and one on each extender, provide fast screed plate heating.
Even Heat DistributionBurners 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 InsulationFull-length insulation over the combustion chamber enhances heating efficiency and minimizes heat transfer to the screed frame.
Glow Plug IgnitionGlow plug ignition is actuated from the main screed control boxes.
Built-In TimerA built-in timer allows 15 minutes of screed plate heating, preventing overheating of the plates.
Electric Screed Plate Heating SystemHighly efficient electric heating system provides warm-up time in 30 minutes or less.
Heating ElementsHeating 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.
Even Heat DistributionMulti-zone heating element configuration provides even heat distribution.
Screed Control PanelScreed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt (HMA) and extended temperature based mixes.
Regulated Screed Plate TemperatureController automatically regulates screed plate temperature to the selected setting.
Minimal Operator TrainingOn-board diagnostics and screed control panel require minimal operator training.
Generator System (Tractor Option)Continuous-duty integrated design ensures peak performance and high reliability.
Industrial, Single-Phase GeneratorIndustrial, single-phase generator operates at 1800 rpm, includes GFCI breaker protection and provides low sound levels.
Single Control SwitchSingle control switch located on the tractor’s operating console activates the generator.
Full PowerFull power is provided to the electric screed and the optional auxiliary power panel while the engine is operating at idle speed.
Dual BearingsDual 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 night-time lighting and other job-site power needs.
Auxiliary Power PanelOptional auxiliary power panel provides 8 kW of power and includes four 120-volt and two 240-volt receptacles.
Ground Fault Circuit InterruptionThe 20-amp receptacles are circuit breaker protected with ground fault circuit interruption (GFCI).
Auxiliary Power Panel DoorAuxiliary power panel door can remain closed while power cords are attached to the receptacles providing protection.
ServiceabilityThe AS2301 Screed is easy and fast to service.
Easy Service And MaintenanceThis screed has been designed for easy service and maintenance with special emphasis given to component access.
Hydraulic Hoses And Electrical WiringHydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service.
Diesel Fuel Burner LinesDiesel 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 FittingsRemote-mounted fittings for vibrator bearings provide simplified lubrication access.
Hydraulic LeaksO-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks.
Nylon Sleeve ProtectionExposed hoses have nylon sleeve protection to reduce abrasion.
Vibrator System Hydraulic LinesVibrator system hydraulic lines are constructed of steel tubing, providing durability and resistance to damage.
High-Quality ComponentsIntegrity of the electrical system is ensured with the use of high-quality components.
Electrical StandardsThe Caterpillar electrical standards, developed to enhance reliability and durability, feature soldered, molded, numbered and color-coded wires. Nylon-braided wrap protects the electrical wires.
