Paving Equipment & Materials Production

Cat asphalt paver.

A line of 8-foot asphalt pavers includes the AP400, AP455, AP500, and AP555 Cat pavers. The pavers have two screed options: SE47 V and SE47 FM.

The front-loading angle of 17 degrees and high bumper clearance simplifies loading without the need for additional blocking materials, according to the company.

The Caterpillar Mobil-trac undercarriage design has a four-year prorated warranty on rubber track belts. The four-bogie system with self-tensioning accumulators and center guide blocks help prevent slippage and reduce wear, while the oscillating bogie wheels help deliver smooth transitions when exiting the cut over transverse joints of mill and fill applications.

Wheeled asphalt paver undercarriage design makes available drive tire options of sand-rib or radial. The AP400 can be equipped with a front-wheel assist option, while the AP500 can be equipped with front-wheel assist or the all-wheel drive option.

The pavers combine a low truck entry height with smaller, 14-inch diameter augers. Operators can control each material feed sensor when utilizing cut-off shoes or when paving at narrow widths, simply switch to manual and utilize the proportional control dial for the feed system.

Eco-mode combines with automatic speed control to reduce fuel consumption, according to the company, allowing the engine to operate at a lower rpm and still deliver the required power. If needed, the engine will automatically adjust to a higher engine speed if certain load conditions are met.

Caterpillar asphalt paver screeds

The screeds pave from 8 feet to 15 feet 6 inches with a maximum width of 20 feet and 20 feet 6 inches, respectively. The screeds have paving depths up to 10 inches for aggregate paving applications.

The SE47 V screed utilizes extenders that are located behind the main screed, enabling material to flow out to the end-gates. The SE47 FM screed is equipped with extenders located in front of the main screed and offers a smaller footprint that reduces handwork at the start of the paving pass. The front-mounted extenders make it easy to quickly reduce paving widths when maneuvering around obstacles by easily drawing material back into the auger chamber.
