Key additions will boost the asphalt paver offering for customers, Mike Woof reports
There are a number of key players in the asphalt paving market that see the value of investing in design, technology and performance. For customers this has resulted in a wide variety of high quality, high performance machines to choose from.The ultra-compact AFW150 mini-paver is the smallest machine in the range, weighs 790kg and can pave widths of 250mm - 1.8m, suiting it to trench repair work or car park applications. The larger AFW/T 270, 350 and 500 models are offered in both wheeled and tracked variants and the wheeled models have four wheel drive and six wheel drive options.
All of the pavers in the Ammann range can be fitted with a vibratory screed or a tamper/vibratory screed, with both electric and gas heating options. that can be heated with either gas or electricity. The AFW270 (wheeled) and AFT270 (tracked) models compete in the 5tonne paver class, with extending screed widths of 1.4-3.33m. The AFW350 and AFT350 are in the 7.5tonne class and have paving widths from 1.83-4.5m. The AFW500 and AFT500 are in the 15tonne class, with paving widths from 2.55-6.5m.
The BF800 models come with a high-capacity hopper and wide bin width for efficient loading, while material flow from bin to screed is said to be smooth and precisely controlled by a hydraulic front flap, a proportional scraper belt, proportional augers and a hydraulic auger height control. Control is provided on both sides from new side-mounted, adjustable operator stations and allow sensors for the scraper belt and augers to be selected and controlled. The new diagnostics system detects and highlights problems with material flow and allows the operator to take action where required.
These pavers come with the firm's ECOMODE machine management system, with four operating modes that help optimise performance and reduce fuel consumption. Other features include ease of maintenance, with good access to hydraulics, electrical and electronic systems and the engine. To help extend component life an automatic central lubrication system automatically supplies lubricant to high load areas such as screed, auger and auger height adjuster.

These new machines benefit from improvements to ergonomics and visibility as well as the low emission
The firm has installed special hydraulic push rollers that minimise bumping from a truck and allow all types of tipper vehicles to unload into the paver hoppers. Meanwhile the risk of cold spots forming in the hoppers is minimised while a large chain, wide throat and specially designed augers also help minimise the risk of material segragation. Sophisticated
Aimed at the US paving market, the VT
With a 7tonne capacity hopper, the 8500B offers the choice of a 50kW
The system includes hydraulic screed extensions that can adjust to deliver smooth mats, while dual vibrators further eliminate seams. Each paver is equipped with two 914mm wide automatic conveyors, while the screed's wear plate is made with abrasion-resistant Hardox 450 steel for increased durability.
An efficient hydraulic system controls each paver, and can be easily operated with just one touch. Each model is driven by hydrostatically-powered tracks through a planetary drive system with variable two-speed torque hubs and internal brakes for continuous power and smooth operation. Maintenance and cleaning are simplified due to a hydraulically-raised hopper bed, while the 8515B also offers a self-cleaning crawler track system.
The pavers are available with high or low-deck options and the 8510B and 8515B have a night operating light package that is optional on the 8500B. A poly pad track, standard on the 8510B and 8515B, is available on the 8500B, while the 8510B and 8515B have the option of a continuous rubber track system.
