Low profile, ease of operation, high-efficiency screed plate heating systems, low-maintenance screed plates and superior serviceability are combined to provide a superior screed, the AS3301C. The AS3301C offers a diesel screed plate heating system or an electric screed plate heating system. Both systems are highly efficient and provide fast warm-up.

Curved nose bar design provides precompaction and enhances material flow under the screed.
Nose bar and screed plate replacement are simplified with tapped holes and studs.
Heavy-duty mounting platforms provide rigid support for screed plates, which simplifies leveling.
The trailing edge adjusting bolt system hardware is plated to provide extra corrosion resistance.
False-wall design reduces mix contact with the sliding portion of the gate, providing easy gate adjustments.
Bolt-on design allows easy end gate installation and removal.
Replaceable wear strip enhances end gate service life.
Full-length end gate contains material, providing an optimal longitudinal joint.
Visual graduated scales indicate the distance that the extenders move in or out.
Hydraulically driven vibrators located on the extenders are synchronized with the main screed to match frequency and amplitude.
Vertical height adjustment allows the extenders to match the main screed height.
Multi-zone heating element configuration provides even heat distribution.
Screed control panel includes three temperature settings that are able to accommodate normal hot mix asphalt and extended temperature based mixes.
Controller automatically regulates the screed plate temperature to the selected setting.
On-board diagnostics and screed control panel require minimal operator training.
Hydraulic hoses and electrical wiring harnesses are cleanly routed and clamped to reduce wear and provide easy service.
Remote-mounted fittings for vibrator bearings provide simplified lubrication access.
O-Ring face seal fittings and couplings provide maximum protection against hydraulic leaks.
Exposed hoses have nylon sleeve protection to reduce abrasion.
Vibrator system hydraulic lines are constructed of steel tubing, providing durability and resistance to damage.
The Cat® electrical standards, developed to enhance reliability and durability, feature soldered, molded, numbered and color-coded wires. Nylon-braided wrap protects the electrical wires.
Electrical schematics detailing wire numbers, wire colors and component part numbers are located in the service manual.
