AP455 Steel Track

AP455 Steel Track

The Cat® AP455 Steel Track Asphalt Paver delivers excellent traction and mobility as-well-as, easy set-up, and a wide paving range, making it the perfect fit for urban streets, parking lots, rural roads and many other small to intermediate-type applications.

Compact Size, Big Opportunities

  • The compact size and small footprint simplify maneuverability in tight spaces for efficient work in urban-type applications
  • Tight 90º turning capability enables the paver to rotate and cover tracks on a return paving pass
  • Standard paving range utilizing the SE47 VT screed is 2.4 m - 4.7 m (7' 10" - 15' 4") with a maximum width of 6.0 m (19' 8")
  • Paving depths up to 300 mm (12") supports aggregate paving applications

Transport Made Easy

  • Machine weight of 15.6 mt (34,341 lb) paver and screed combination enables easy transport on a variety of trailer types
  • Length of less than 5.6 m (18' 4") and width of 2.55 m (8' 4") accommodates machine transport without special permits in many regions
  • When equipped with 225 mm (9') extensions, transport width is 3 m (10') and paving width extends to 5.1 m (16')
  • The front-loading angle of 17º and high front bumper clearance reduces the need for additional blocking when loading onto various trailer designs
  • Raising or retracting the canopy is fast and easy with both electric or manual options available
  • Front, middle, and rear tie-down locations make securing the paver efficient for quick travel to the next job site

Exceptional Mobility

  • Steel track undercarriage provides exceptional mobility, outstanding traction, and smooth travel for unmatched maneuverability around the job site
  • Counter-rotating tracks provide excellent maneuverability in tight quarters
  • Automatic track tensioning system, double carrier rollers and track guide plates help ensure the tracks are properly aligned and tensioned to provide smooth travel
  • Triple grouser track shoes with profiled polyurethane pads provide strength and durability while also delivering smooth travel and minimal base disturbance on uneven surfaces
  • Efficient track plow design pushes material away from the tracks and helps eliminate density variations caused by track compression

Smooth Material Flow

  • Variable speed, single amplitude tamper system with variable frequency screed plate vibration delivers material flow and tight mat textures
  • Low truck entry height and short front apron enhances material flow while simplifying clean out
  • Feeder system design with 355 mm (14") diameter augers provides consistent material flow across the screed for efficient flow at both narrow and wide paving widths
  • Narrow auger chamber keeps material moving and helps eliminate stagnate patches
  • Independent control of each material feed sensor, simply turn off the sensor for manual proportional feed control

More Comfort

  • Optional ventilation system draws fumes from the auger chamber and redirects them away from the operator for a more comfortable working environment
  • Single sliding console enables operation from either side of the machine
  • Dual independent seats swing out 40º beyond the platform for good visibility to curbs and obstacles
  • Optimized height and integrated exhaust provide unobstructed visibility around the machine
  • Optional screed and paver mounted umbrellas offer protection from direct sunlight
  • Heated seat option delivers comfort in cool weather conditions
  • High visibility 76 mm (3") seat belt helps with crew safety compliance

Easy Viewing Displays

  • High-definition, touchscreen displays with adjustable brightness control for all types of lighting conditions, including direct sunlight
  • New touch screen operating display with simplified menu structures, intuitive graphics, and short-cut keys help simplify machine adjustments
  • Single-touch functions from main screen include screed heat, wash-down system, vibratory activation, ventilation system, and the accessory panel
  • Cat® Grade Control or Basic Grade Control options available
  • Operating displays can be tailored to specific language requirements with multiple options available
  • Wash-down system includes level indication

Low Owning and Operating Costs

  • Durable Cat C3.6 engine provides 90 kW (120 hp) of power with variations that meet U.S. EPA Tier 4 Final and EU Stage V emission standards. The Cat 3.6 engine also meets Brazil MAR-1 and UN ECE R96 Stage IIIA emission standards, equivalent to U.S. EPA Tier 3 and EU Stage IIIA.
  • Single source supplier of Cat engines and machine parts helps maximize uptime
  • Exclusive Eco-mode and Automatic Engine Speed Control reduce fuel consumption and lower sound levels for better comfort and communication
  • Conveyor bed plates and chain guards designed to minimize labor requirements and provide lower cost replacement
  • Maintenance-free high torque motors reduce service requirements for the auger and conveyor drive systems

Product Link™ Elite

  • Make timely, fact-based decisions to maximize efficiency, improve productivity, and lower owning and operating costs
  • Easily track location, machine hours, fuel usage, and idle time in real time
  • Diagnostic codes are made available through online web applications
  • Remote flash for easy software updates
  • Scheduled maintenance and Scheduled Oil Sampling notification
  • Remote disable deactivates the engine for enhanced security

Service and Repair Kits

  • Paver and screed service and repair kits include all the parts necessary to complete specific repairs
  • Cat genuine parts are manufactured to precise specifications and designed for optimal performance and maximum uptime
  • Repair kits are identified by a single part number to make ordering easy
  • Select kits are available to be packaged as a kit by the dealer for over-the-counter purchases or through the dealer service shop


  • The Cat® C3.6 engine is available in configurations that meet EU Stage V emission standards.
  • Cat EU Stage V diesel engines are required to use ULSD (ultra-low sulfur diesel fuel with 15 ppm of sulfur or less) or ULSD blended with the following lower-carbon intensity fuels up to: 20% biodiesel FAME (fatty acid methyl ester) or 100% renewable diesel, HVO (hydrotreated vegetable oil) and GTL (gas-to-liquid) fuels. Refer to guidelines for successful application. Please consult your Cat dealer or “Caterpillar Machine Fluids Recommendations” (SEBU6250) for details.
  • The engine, fuel and hydraulic systems are equipped with ecology drains for easy servicing and to help prevent spillage.
  • Cat Scheduled Oil Sampling (S•O•S) Services helps reveal excessive wear, contaminated fluids or other “unseen” issues that can shorten component life. In many cases, you can extend oil and coolant change intervals by using fluid monitoring. Consult your Cat dealer or the machine’s operation and maintenance manual for more information.
  • Cat Grade with Grade and Slope for Asphalt Pavers allows for accurate material planning to help reduce overages during the paving process and increase final project quality for a longer lasting road surface.
  • Don’t waste fuel idling. Cat VisionLink® online fleet monitoring helps you manage idle time and reduce fuel burn and greenhouse gas emissions.
  • VisionLink displays the CO2 emissions for monitored assets, calculated by fuel type for the Runtime Fuel Burned each day in a selected date range.
