CB68B Caterpillar CB68B Specifications & Technical Data (2019—2026)

Cat Compaction Control

Cat Compaction Control improves quality and efficiency by providing information that enables the operator to determine when compaction meets specifications. The system can be scaled from a simple real-time compaction readout to a fully featured data mapping capability. Solutions to fit your needs, able to grow with you. The optional Cat Compaction Control helps contractors increase efficiency and productivity while recording data for quality control documentation and future planning.

Highly Reliable

Water-resistant displays Factory installed components, consistent routing and location Sealed components withstand heat, moisture, and vibration Built-in temperature sensors provide better reliability than bail-type sensors Lockable enclosure provides vandal protection Easy diagnostics, compatible with Cat Electronic Technician

Increased Reliability

Factory installed and sealed components Resistant to heat, vibration, moisture Built to meet the rigors of milling application environments

Features

Small classes offer hands-on opportunities Consulting solutions to ensure success on the job Hundreds of years of industry knowledge and experience worldwide—average of 20 years per person

Temperature Sensors

Dual infrared sensors mounted on the front and rear of machine deliver real-time readingsKeep operator informed of when to begin rolling and when to stopHelp avoid tender-zones that often occur in the 104°-110° C (219°-230° F) temperature rangeOptimal mat temperatures for compactionUpper limit is around 149° C (300° F)Lower limit is around 85° C (185° F)Eliminates hand-held devices

Pass-Count Mapping

Achieve target density and increase roller efficiencyRecord and monitor pass pattern in order to ensure consistent coverageOptimize drum overlap in order to keep pace with the paverSimplify nighttime operationEliminate second guessingPrevent incomplete passes such as stopping short

Temperature Mapping

Provides a visual readout of mat temperature in order to keep the machine in the proper temperature rangeRecords and monitors temperature for future analysis of the proper temperature range

New

Smooth drum models over 10 metric ton can be configured with MDP and CMV, providing the widest range of applications.

Additive System Options

Water Spray System automates the addition of metered water to the mixing chamber, allowing the machine to easily mix the proper measured amount to the materials. It provides an infinitely variable volume capacity of 114 to 1136 liters (30 to 300 gallons) per minute with two nozzles that provide a high flow range and a low flow range. For water use only—not for use with emulsions.

Water Spray and Emulsion Spray System

Water Spray and Emulsion Spray Systems are both installed to allow simultaneous or individual system operation.

Auto Adjustable Compaction

Automatic feature simplifies operation and optimizes compaction performanceFront and rear drums are equipped with auto-adjusting technology that delivers the highest level of amplitude without over-compactingEliminates de-coupling and damage to asphaltEach drum is controlled independently to deliver uniform compaction that helps meet quality standards

GNSS Mapping

Provides operator with visual indication of work status. Maps data to position where it was measured. Pass count, coverage. Choose level of accuracy: SBAS or RTK.

Precise Control

More accurate control maximizes mix utilization and saves money. True averaging; sonic sensors utilize 5 transducers, 2 readings discarded and 3 averaged. 10-point Auto-Calibration; eliminates over/under adjustment from single calibration point. Cross-coupling; slope and elevation maintained with height adjustments. True 9 m (30') sonic averaging beam; tow point movement is 1/3 of total grade deviation. Cutting to the proper grade maximizes smoothness and manages material usage. Typical setup (shown) provides 11 data samples for true averaging, compared with 3 samples from typical competitive systems. Cross coupling capability improves machine responsiveness, providing superior surface quality and accuracy. Automatic calibration ensures consistent setup and delivers optimal performance.
