Fuel Efficient and Quiet

Efficient power management and advanced Eco-mode optimize fuel efficiency and lower sound levels.

Quick Starter

Exclusive 70 kW integrated generator delivers fast heating screed plates, quiet or quick heating options, and simple monitoring. The system is designed to save time and fuel while providing reliability for the life of the paver. Advanced diagnostics keep the screed heating, even in the event of a sensor failure.

More Control

The dual operator stations provide complete control and good visibility to truck drivers from either side of the operating platform. Station transfer occurs with the simple press of a button and all the settings automatically transfer making the transition from side to side very easy.

Water Resistant Displays

The water resistant displays provide excellent reliability and meet IP67 common water submergence ratings. The switches have been tested to one million cycles without failure. If a failure does occur, grouped components are serviceable and it’s not necessary to replace the entire console.

More Efficient Delivery

High production features include large throughput capacity and over-sized feeder components that enable the system to run slower, limiting wear while also reducing fuel consumption.

Mobil-Trac Undercarriage

Maintenance-free and unmatched traction in both smooth or tread-bar style belts. The Mobil-Trac undercarriage provides excellent flotation, smooth travel, and high speed capability for better mobility around the job site.

SE-Series Screeds

The SE-Series screeds provide new heating technology, increased durability, easy adjustment, and better efficiency. The SE50 V offers a paving width out to 6.5 m (21.7 ft), while the SE50 VT can pave up to 7.5 m (24.7 ft). The SE50 V utilizes vibratory screed plates, while the SE50 VT combines tamper bars and vibration to tuck material under the screed plates.

Cat Grade Control

Cat Grade Control is a factory-integrated guidance system that helps remove irregularities from the surface and control mat thickness for increased production, lower operating costs, and higher profitability.

Cat C4.4 ACERT Engine

The C4.4 engine provides 106 kW (142 Imperial hp, 144 metric hp) of power and meets regional emissions requirements including U.S. EPA Tier 4 Final and EU Stage IV emission standards.

Eco-mode

Eco-mode utilizes an engine speed of 1650 rpm and reduces fuel burn by up to 5% over Cat E-series pavers while also lowering sound levels even more.

Automatic Engine Speed Control

When automatic engine speed control is activated, the engine speed is reduced to an idle speed of 1000 rpm when the propel lever is moved to neutral, or to 1300 rpm when screed heat is active.

Advanced Eco-mode

Eco-mode and automatic engine speed control when activated together modify the engine rpm based on load factors. When activated the engine will operate at 1650 rpm when paving. If the upper power threshold is exceeded, the engine speed will increase to 2200 rpm and remain there until the demand drops below the threshold and remains there for 30 seconds. This advanced technological enhancement ensures reliable performance.

Quiet Heating

Quiet heat mode operates at an engine speed of 1300 rpm and provides screed plate heating in under 15 minutes.

Quick Heating

Quick heating mode provides a heat-up time in under 35 minutes when equipped with the wide-width paving package. Quick heat does not heat any faster than quiet heat when the screed is at standard extendable widths.

Temperature Ranges

Three preset heating options provide a wide range of temperatures for various mix designs; Low is 110 degrees C or 230 degrees F, medium is 130 degrees C or 266 degrees F, high is 160 degrees C or 320 degrees F.

Better Visibility, Exceptional Comfort

The dual independent operating stations can extend beyond the frame for good all-around visibility. The low profile, front-mounted cooling system enhances forward viewing and the redesigned auger assembly optimizes visibility to material height in front of the screed. The heated seat option, multiple seat adjustments, and tilting consoles conform to the operator to provide day-long comfort. The top-mounted cooling system directs fumes, hot air, and fan noise away from the crew for a cooler and quieter working environment.

Fumes Management

The exclusive ventilation system draws fumes from the conveyor tunnel as well as the auger chamber, and redirects them away from the operator for a more comfortable working environment.

Single Touch Operation

Single touch features for the auto-fill feeder system, feeder system activation, and hopper control, allow operators to concentrate on truck exchanges and other duties for improved efficiency.

Simple Technology

Technology helps operators perform. Intuitive symbols and large graphics simplify operation, while the interactive LCD display with touchscreen access to generator activation, screed temperature control, and mix height adjustment, increase efficiency.

Auto-Fill Feeder System

The auto fill feeder system simplifies starts by alternating the conveyors and augers until the mix height reaches the sensor set point. This unique system eliminates manual activation and constant monitoring for more consistent performance.

Single Touch Feeder System

The two augers and two conveyors can be activated automatically with a single switch to simplify setup. Each auger and each conveyor can still be operated independently when needed.

One Touch Hopper Control

The hopper wings and hydraulic apron can be folded with a single touch and release. The system can be tailored to activate left or right wings, or the front hydraulic apron independently or together.

Cleanout and Warm-Up Mode

This feature activates the augers, conveyors, and tamper-bar (if equipped) at a reduced speed, allowing the application of release agents that help prevent material build-up.

Mix Height Adjustment

Mix height adjustment in front of the screed can be modified from the tractor LCD display for increased versatility when needed.

Hydraulic Mainframe Extensions

The optional 457 mm (18″) hydraulic mainframe extensions attach to the auger assembly and provide smooth material flow out to the extenders. They retract with the screed extensions when reducing paving widths.

Multiple Feed Sensor Options

The feeder system can be tailored to automatically operate with 0, 2, or 4 feeder sensors. When paving with 0 sensors due to a failure, simply set the feeder system to automatic and adjust the mix height setting, no need to cycle the manual switch as previous models required.

Easier Service

Hardware-free bed plates simplifies replacement and bottom side mounting hardware for the chain guards eliminates bolt wear and material build-up for easier service.

Performance

The Mobil-Trac undercarriage minimizes tow-point movement. The front and rear bogie sets crawl over obstacles and help maintain ground contact. The smooth belt option performs well on soft base materials and fresh mats. The tread-bar design excels on loose paving/transport conditions.

Durability

Self-tensioning accumulators, center guide blocks, and rugged internal belt cables ensure durability. The components are rubber coated in order to shed asphalt and prevent accumulation.

Screed Heat Technology

Exclusive zone monitoring allows heating to continue in the event of a temperature sensor failure. The system also monitors heating elements for failure conditions and helps eliminate unnecessary replacement.

Easy Adjustment

Feeder system ratio adjustment capability from the screed provides additional versatility. Standard power adjustment for extender height, slope, and crown, allows for on-the-go adjustment at standard and maximum paving widths.

Two-Speed Proportional Extender Control

Exclusive two-speed proportional extender control offers slower speed for precise control around obstacles and quick reaction when extending paving widths.

Simple Replacement

The heating elements slide out for easy replacement, no need to remove the screed plates. In addition machined screed frames simplify screed plate replacement and leveling.

Tamper Bar Screed Option

Tamper bar equipped screeds increase density as it tucks material under the screed plates. Three stroke settings of 2, 4, and 7 mm and the variable tamper speed of 700 to 1800 rpm provide versatility.

Wide-Width Paving Packages

Exclusive power controls simplify adjustment across the entire paving width for better mat texture and quality. The innovative design utilizes extender slope to attach wide-width paving packages and eliminates the need for additional lifting devices.

Easy Operation

F-Series pavers allow Cat Grade Control to be operated from any of the two tractor or two screed consoles. Split screen mode can be setup to monitor each side of the screed, enabling single person operation.

Precise Control

More accurate control maximizes mix utilization and saves money. True averaging with sonic sensors that utilize 5 transducers, 2 readings are discarded and 3 averaged. A 10-point Auto-Calibration eliminates over/under adjustment from a single calibration point. Cross-coupling, slope, and elevation are maintained with height adjustments. The true 9 m (30 ft) sonic averaging beam modifies tow point movement by 1/3 of total grade deviation.

Highly Reliable

Water-resistant displays, factory installed components, and consistent routing deliver performance. Sealed components withstand heat, moisture, and vibration, while the built-in temperature sensors provide better reliability than bail-type sensors.
