Due to the rapid growth of heavy transport, the global road network is showing clear signs of ageing in many places.
In order to maintain smooth traffic, all road rehabilitation works need to meet the same requirements, no matter where they are carried out; in other words, they must be cost-effective, as environmentally friendly as possible and, above all, completed quickly.
More than 100 Amman products, including many new ones, were on display at the recent Bauma exhibition in Munich, Germany, marking the 150th anniversary of the company.
The products and services on display include light equipment, in particular a new hydrostatic vibratory roller production line, which will replace the existing machine production line. The main features include advanced compaction technology and three-axis excitation system to keep the movement of the plate consistent and enable smooth travel.
A new type of reversible vibrating plate compactor is introduced. The board includes a low vibration handle to help keep it fresh, comfortable and productive.
In terms of rollers, Ammann's ARX 91 articulated series roller (ARX 91 articulated series roller) is also on display at the exhibition. The output is provided through a combination of drum size, frequency, and amplitude.
The engine of the ART 280 static tire roller can meet different emission levels. Amman's modular, easy-to-load ballast system allows the weight of the machine to be adjusted from 9 tons to 28 tons in an hour with the help of a forklift.

It is said that the new series of ARX light series rollers will make it easier for operators to work near obstacles such as kerbs.
The ARS 122T3 soil rammer uses a Cummins BS-III engine, equivalent to the third layer. The ARS series is characterized by Amman's concept of no rear axle.
The ARP 95 ST5 pivot steering roller has a redesigned main frame that allows the machine to work up to 3070 mm wide in offset configuration. Amman said that this is the market of the same size wheel working width of the largest roller.
Concrete and asphalt products are also on display. These facilities include the ABC ValueTec asphalt mixing plant, the transport optimization CBT 130 TB Elba concrete mixing plant and the RSS 120m crusher, iron separator and sieving machine, which is a mobile machine for the preparation of recycled asphalt for asphalt mixing plants.
According to the National Asphalt pavement Association, the production of warm mix asphalt (WMA) in the United States has exploded in recent years, from 19.2 million tons in 2009 to 86.7 million tons in 2012, an increase of more than 400 percent in just three years. In 2012, 88 per cent of WMA products used mechanical foaming devices, and it is clear that the use of foamed asphalt follows the same steep growth trajectory.
To help you understand the new WMA environment for foamed asphalt, the National Cooperative Highway Research Project released a new report on test methods, performance measurement and hybrid design earlier this year. (a copy of the report can be downloaded by searching for
In general, the warm mix asphalt process reduces the viscosity of liquid asphalt by a variety of means, so that the aggregate is coated at a temperature of 35 ~ 100 degrees lower than that of the traditional hot mix asphalt. It is by mixing a variety of solid or liquid chemical modifiers, such as Sasobit or Evotherm, with asphalt mixture in the factory, but it can also be mixed with water by foaming liquid asphalt in the factory, just as it is mixed with aggregate.

In North America, with the popularity of European technology from the Federal Highway Administration (Federal Highway Administration) and Napa (NAPA), WMA became popular in the 1990s. Prior to this, another type of foamed asphalt-cold mix asphalt made in portable factories (or using recyclers / recyclers on site), and up to 100% recycled asphalt pavement-was widely used. It is used for foundation stability and full depth regeneration of road.
Total Asphalt recently launched its new website in the UK, giving the industry and the public the opportunity to see all the products, solutions and solutions in which the company is involved. The front and center of the new site is a series of useful videos outlining the six pillars built by the international giant.
