CB15 Tandem Vibratory Roller

The CB15 asphalt compactor offers enhancements that simplify operation, provide versatility, and deliver excellent fuel economy. Rotary dials, oscillatory vibration, and 360 degree seating option make this compactor a perfect match for urban streets, rural roads, highways, interstates and other high-production applications.

Simple to Operate, Easy to Learn

  • 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
  • Dual side access on ROPS/Canopy machines provide operators with flexibility to mount and dismount the machine (U.S. and Canada only)

Better Fuel Economy

  • Get up to 10% better fuel economy with the Cat  C4.4 engine and standard Eco-mode
  • The C4.4 engine provides 106 kW (142 hp) of power and meets regional emissions requirements
  • Unique Eco-mode design modifies engine speed based on load requirements; high amplitude vibration utilizes higher engine speed, while static rolling conserves fuel and operates at low engine speed with even lower sound levels

Easy Vibratory System Set-up

  • Five amplitude system utilizes a single frequency with five distinct amplitudes that provide excellent performance on thick lifts and rigid mix designs
  • Versa Vibe™ vibratory system creates a 2-in-1 machine with four amplitudes and two frequencies; two settings for lighter hitting and higher working speeds on thin lifts; and two settings for heavier hitting and slower speeds on thick lifts and challenging mix designs
  • 2-amplitude/2-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

Compaction Options Include Oscillation

  • 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

Ensure Mat Coverage with Compaction Control

  • 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

Prevent Build-Up, Keep the Drum Surfaces Wet

  • 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
  • Integrated freeze protection kit (optional) provides protection in cold temperatures when machine is not in use

Boost Performance with Enhanced Visibility

  • Optimize sight lines with 360  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

Product Link™

  • 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
