Caterpillar Inc. has added a new compact line of asphalt pavers and screeds to its paving products family. The standard eight-foot size-class paver and screed combinations include models AP400, AP455, AP500, and AP555 asphalt pavers as well as the SE47 V and SE47 FM asphalt screeds.

The compact size, small footprint and maneuverability are well-suited to paving in confined areas such as narrow streets, small parking lots and other urban-type applications. The standard paving range using the SE47 V screed is eight to 15.5 feet (2.4 to 4.7 m) with a maximum width of 20 feet (6.1 m), while the standard paving range of the SE47 FM screed is eight to 15.5 feet (2.4 to 4.7 m) with a maximum width of 20.5 feet (6.2 m). Paving depths up to 10” (254 mm) supports aggregate paving applications.

With a length of less than 18’ 6” (5.6 m) and width of 8’ 6” (2.6 m), the 13- to 15-ton size-class machines can be transported without special permits. Furthermore, the front-loading angle of 17 degrees and high bumper clearance simplifies loading without the need for additional blocking materials.

These machines have simplified menu structures with single-touch activation for screed heat, washdown, and ventilation systems, all from the main menu. As with all Cat pavers, these new models also provide single-touch activation of the feeder system and hopper fold functions.

AP400 and AP455 pavers are equipped with a Cat C3.6 engine, while the AP500 and AP555 use the Cat C4.4 engine. Both engines meet Tier 4 Final emission standards.

The SE47 V screed uses extenders located behind the main screed to enables material to naturally flow out to the end-gates for smooth, stable performance. 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.
