Benefits and Features

  • Large, full-color displays keep the operator informed of machine functions including water and fuel levels, impact spacing, and mat temperature
  • Innovative hand-wheel steering technology delivers precise control and good forward visibility
  • Easily activate the vibratory system, water spray system and drum offset with the multi function propel handle
  • Machine functions with LED indicators have been independently
  • grouped for simplified control and quick activation
  • Rotary dials with green light indicators provide quick visual reference and fingertip feel for quick adjustment to speed control and water spray timers

  • Get up to 10% better fuel economy with the Cat® C3.6 engine and standard Eco-mode
  • The C3.6 engine provides 74.4 kW (100 hp) of power and meets U.S. EPA Tier 4 Final and EU Stage V emissions
  • Unique Eco-mode design modifies engine speed based on load requirements; high amplitude vibration utilizes higher engine speeds, while static rolling conserves fuel and operates at low engine speed with even lower sound levels

  • Two-amplitude/two frequency vibratory system automatically optimizes amplitude and frequency with a single switch for simple thin/thick lift operation
  • Reach compaction goals with automatic speed control; green indicators help ensure travel speed matches correct impact spacing

  • Oscillatory vibration on the rear drum combined with standard vertical vibration front drum delivers both performance and versatility
  • Oscillation system utilizes proven pod style eccentric weight technology developed by Caterpillar
  • 2 year/2000 hour service interval helps maximize uptime and limit maintenance costs.
  • Durable power transmission belt delivers 2-times the load capacity of timing belt systems leading to extended life
  • Standard drum shells offer exceptional long term life on a variety of mix designs and delivers outstanding mat texture, density, and smoothness.

  • Pass-count and Temperature Mapping combines infrared temperature sensors with GPS mapping to keep the operator informed of current asphalt temperatures, machine position, pass-count, and layer coverage
  • Compaction Meter Value (CMV) utilizes a drum-mounted accelerometer to measure the combined stiffness of the asphalt layer, base layer, and sub-base layer to indicate road structure quality beneath the surface
  • Machine to Machine communication helps keep rolling patterns in sync by sharing mapped data such as CMV, temperature mapping, and pass count coverage between multiple machines

  • High capacity water tank provides long duration between fills
  • Dual water pumps provide back-up capability and alternate with direction of travel to maximize service life
  • Triple filtration prevents clogs with filters located at the fill point, water pumps, and spray nozzles
  • Simple rotary dial provides adjustable spray settings and intermittent modes that help conserve water
  • Integrated freeze protection kit (optional) provides protection in cold temperatures when machine is not in use

  • Optimize sight lines with 360º seating option; always face the direction of travel
  • LED Lighting delivers excellent job site illumination while conserving energy
  • Night-lighting option provides additional illumination to the ROPS/Cab, drum edges, and drum surfaces

  • 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
  • Diagnostic codes are made available through online web applications
  • Remote flash works around your schedule to ensure your machine’s software is up to date for optimal performance
