Compact asphalt pavers are versatile machines that are suitable for road repairs and utility work as well as for paving bike paths, pedestrian paths and underground garages or multi-storey car parks.
One of the smallest units on the market is the tiny AFW150-2 model from 6791 Ammann, which is designed for paving work such as road repairs in cities. The machine’s screed construction means that widths of just 250 mm can be leveled. One of the main uses for such narrow pavement widths is laying asphalt between tram tracks on urban streets. In the meantime, the machine can be used for a maximum paving width of 1.3 m, with the screed being at full hydraulic expansion. When using screw fastenings attached to the screed, the maximum paving width is 1.65 m. However, the machine is only available with a vibrating screed. According to the company, the machine can be used for road restoration work after utility works, as well as for paving bike paths or pedestrian paths.
The compact city paver BF200 from 172 BOMAG weighs 6 tons and is considered versatile and mobile. The power comes from an emission-compliant diesel with 55.4 kW. Although compact, it can pave residential streets as well as bike lanes, and carry out restoration work on milling or trenching work. When the screed and the hopper wings have been retracted, the machine can drive through a 1.2 m wide door opening. The maximum paving width is 3.4 m. The machine can also be used for paving tram tracks on urban roads. AA rammed screed is built in as standard, although vibratory screed may also be available in the future.
The machine has a novel two-position platform on which the operator can stand on the deck for an all-round view of the work area, hopper and screed. By using the lower position, the operator can observe the screed more closely. The control column can be tilted at the operator’s discretion.
206 The proven models F1200C and F1200CS from Dynapac offer paving widths from 1.2 to 3.1 m and throughputs of up to 300 t / h. Both machines have 201 Deutz diesel engines with an output of 54 kW and are available with Tier 3 or Tier 4 Final versions as well as optionally with electric or gas heating for the screeds. With the 5.8-ton F1200C, there is a choice of two screeds with only vibration. The 5.9-ton F1200CS has the choice between two screeds with tamper bar and vibration.

The compact Super 800 paver from Vögele is equipped with the company’s AB220-TV screed, which has a manipulation bar and vibrations. The company’s Super 700 model uses the AB 220 V screed only with vibrations and is aimed at the North American market. Whether for the AB 220TV or AB 220 V variant, the paving widths range from 1.2 to 2.2 m. Screw-on extensions of the AB 220 V enable paving widths of 3.2 m, while screw-on extensions for the AB 220 TV variant enable paving widths of up to to allow 3.5 m.
The Super 800 is compact, has a track width of 1.14 m, a clearance width of 1.4 m and a height of 1.98 m, which enables operation in the tightest spaces between obstacles and, for example, within parking areas.
The Super 800 has a hydrostatic drive system with separate pumps that work in closed circuits. According to the company, this enables the company to precisely steer and maneuver the Super 800 for work in confined spaces. At the same time, the company claims that the smooth operation is optimized due to the crawler tracks with additional support rollers.
The Super 800 is equipped with a large material hopper for its overall size. The machine can pick up 5.8 tons of asphalt. This is available on request with an asymmetrical geometry that has a hydraulically foldable upper part on the left side of the hopper. Due to the special design, material can also be fed in when the feed vehicle cannot dock centrally in front of the paver, e.g. B. when paving on walls or other obstacles.
The power comes from a Deutz diesel engine with an output of 55.4 kW, which enables a maximum travel speed of 30 m / min. A variable speed fan ensures efficient cooling and is intended to reduce the engine load, the noise level and also the fuel consumption. The two models are made available with different engine variants to meet both highly regulated and unregulated markets for compliance with emissions regulations.
