Simple to Operate

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

Better Fuel Economy

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

Easy Setup

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

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

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

Prevent Build-Up

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

Boost Performance

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
