Ammann’s ultra-compact AFW 150-2 paver suits use in confined working areas

Compact asphalt pavers are versatile machines, useful for road repairs and utilities jobs, as well as paving cycle lanes, pedestrian footpaths and underground or multi-story car parks.

One of the smallest units on the market is 6791 Ammann’s diminutive AFW150-2 model, which is designed for paving work such as urban street repairs. The design of the machine’s screed means it can pave widths of just 250mm. One of the key applications for such narrow paving widths is for laying asphalt in between tram tracks on urban roads. Meanwhile the machine can be used for a maximum paving width of 1.3m with the screed at full hydraulic extension. Using bolt-on attachments fitted to the screed, maximum paving width is 1.65m. The machine is available with a vibrating screed only however. According to the firm, the machine can be used for road reinstatement work following utilities works as well as paving cycle lanes or pedestrian paths.

Moving up in scale, 172 BOMAG’s compact BF200 city paver weighs 6tonnes and is claimed to be versatile and mobile. Power comes from an emissions compliant diesel delivering 55.4kW. Although compact, it can pave residential roads, as well as cycle lanes and can handle reinstatement work on milling or trenching jobs.  When the screed and hopper wings are retracted, the machine can pass through a 1.2m-wide doorway. The maximum paving width is 3.4m. while the machine can also be used to pave within tram tracks on urban road works. A A tamper bar screed is fitted as standard although a vibration type screed may be available in the future also.

The machine has a novel dual position platform, with the operator able to stand up on the deck for an all-round view of the working area, hopper and screed. Using the lower position meanwhile allows the operator to watch the screed more closely. The control column can be tilted to suit the operator’s preference.

206 Dynapac’s proven F1200C and F1200CS models offer paving widths of 1.2-3.1m and throughputs of up to 300tonnes/hour. Both machines have 201 Deutz diesels delivering 54kW and are available with Tier 3 or Tier 4 Final variants, as well as a choice of electric or gas heating for the screeds. The 5.8tonne F1200C has a choice of two screeds with vibration only. The 5.9tonne F1200CS has a choice of two screeds with tamper bar and vibration.

Vögele’s compact Super 800 paver is fitted with the firm’s AB220 TV screed, which features a tamper bar and vibration. Meanwhile, the firm’s Super 700 model uses the AB 220 V screed with vibration only and is aimed at the North American market. Whether for the AB 220TV or AB 220 V variant, paving widths range from 1.2-2.2m. Bolt on extensions to the AB 220 V allow paving widths of 3.2m while bolt-on extensions for the AB 220 TV variant allow paving widths up to 3.5m.


Compact in size, the Super 800 has a track width of 1.14m, a clearance width of 1.4m and a height of 1.98m. This allows it to operate in confined spaces between obstructions as well as inside parking areas for example.

The Super 800 features a hydrostatic drive system with separate pumps that operate in closed loops. According to the firm, this allows the Super 800 precise steering and manoeuvring for working in confined areas. At the same time, the company claims that smooth running is optimised due to the crawler tracks that feature additional support rollers.

The Super 800 is equipped with a large material hopper for its overall size. The machine can hold 5.8tonnes of asphalt. This is available with an asymmetrical geometry on request, featuring a hydraulically folding upper section of the left-hand hopper side. The special design allows material to be supplied even when the feed vehicle is unable to dock on centrally in front of the paver, such as when paving alongside walls or other obstacles.

Power comes from a Deutz diesel engine rated at 55.4kW, which allows a maximum paving speed of 30m/min. A variable speed fan provides efficient cooling and is said to lower engine load, noise levels and also fuel consumption. The two models are being made available with different engine variants to suit highly regulated as well as non-regulated markets for emissions compliance.

    New generation wheeled pavers aimed at use in territories such as the UK, Italy, South Africa and Southern Germany are now coming to market. Pavers in these countries are often expected to be driven from one part of a site to another or for short distances, which is why the additional mobility of the wheeled machine is preferred in many instances over similarly-sized tracked models. This preference for wheeled units comes in spite of the greater stability offered by tracked machines. BOMAG, Caterpillar and
