The AP555F, AP655F and AP1055F are equipped with the Mobil-Trac undercarriage.

Cat F-Series pavers offer intuitive, accessible technology and a quick-heating screed system that increases production and efficiency. The AP500F, AP600F and AP1000F feature wheeled undercarriages. The AP555F, AP655F and AP1055F are equipped with the Mobil-Trac undercarriage.

The six paver models come equipped with a new screed platform, the SE-Series screeds, available with vibratory only or vibratory and tamper bars. SE-Series screeds deliver enhanced ride and mat qualities while providing versatility in urban areas. Some paver models have screed packages available with the capability of paving up to 33 ft. (10 m) wide.

Power is provided by a Cat ACERT engine, which meets U.S. EPA Tier IV Final emission standards. Standard Eco-mode, when used with automatic engine speed control, efficiently manages engine RPMs to optimize fuel economy and reduce sound levels.

An integrated generator is directly connected to the paver engine. The refined heat distribution of the SE-Series screeds allow the generator to bring the screed plates to the proper temperature in approximately 15 minutes. Screed-heating system diagnostics automatically compensate in the event a screed temperature sensor fails, allowing consistent, uninterrupted paving. Screed plates are made from proprietary abrasion-resistant steel, extending wear life. A machined screed frame eases installation of the screed plates, which bolt flat to the frame. Screed extensions are equipped with exclusive two-speed proportional control for enhanced responsiveness near obstacles and more precise control, according to the manufacturer.

Controls are simple yet flexible. Crews who prefer limited options have an organized, efficient control system at their fingertips. More functions, including new technology functions, can be accessed through the color touchscreens. The most frequently used functions are still controlled by switches.

Ratio control for the conveyors can be controlled from the screed. Likewise, the tractor operator can adjust mix height for increased flexibility.

Propel and feeder system settings transfer between stations with the touch of a single switch. Speed, as well as operation and travel modes, are automatically adjusted at both stations.

Tractor operators can make screed adjustments or operate Cat Grade Control from the tractor consoles. A single-button auto-feeder system does the work of four switches. An auto-fill button alternates between running the augers and conveyors, helping operators build a proper head of material from the start.

Models equipped with the Mobil-Trac System (MTS) feature oscillating bogies and smooth or treaded rubber belts. The oscillating bogies minimize deviations and tow-point movement, leading to smoother mats. MTS provides superior traction and maneuverability while enabling travel speeds that match wheeled pavers.

Models equipped with a wheeled undercarriage are available with optional six-wheel drive, which optimizes traction and provides 200 percent more front pull force over previous models. A front-wheel assist or four-wheel drive option increases front-wheel pull-force by 50 percent over previous models.
