Asphalt milling, paving & compaction

In Japan, major efforts are being made to both conserve energy and materials, while also delivering high quality airport runways. At Haneda Airport, as well as at the Fukuoka, Chitose and Sendai airports, innovative use is being made of asphalt paving equipment from Sumitomo. The latest model HA60W J paver from Sumitomo is being used to lay warm mix asphalt, while the contractors is also using sophisticated control technology. To minimise disruption to flight schedules, construction work at Haneda has been

The latest asphalt testing equipment brought onto the market is both innovative and highly accurate as Kristina Smith reports Advanced pavement design requires advanced test equipment. And advanced test equipment takes time and money to design, engineer and produce. But if your expensive testing machine could perform a few more tricks, buying one would make financial sense to more organisations. This is the thinking behind IPC Global’s new Uniaxial Fatigue Test Kit for its Asphalt Performance Mixer Tes

Timely maintenance using proven cost-effective methods can extend the life of a highway by many years as Patrick smith reports Highways are expensive assets to construct, and the wear and tear of modern traffic means that regular maintenance will delay costly repairs or in extreme cases reconstruction. There are a number of methods of carrying out such maintenance, and these include the use of slurry seals and micro-surfacing, which are cold mixed asphalt which is a mixture of graded aggregate, asphalt emul

Consultants have specified Tensar techology in the rebuilding of a deteriorating Polish highway in order to meet current standards. The use of Tensar geogrids enabled consultants Drotest and Dro-konsult Warsaw to create a stable asphalt pavement quicker and more economically than using conventional construction methods, says Tensar. The 40km long road, which connects Bartoszyce and Ketrzyhn, had exceeded its design life and clearly showed its structural weakness with bad rutting, extensive fatigue crackin

Kilsaran, a leading Irish contractor, building materials supplier and producer of concrete products, has completed construction of 11,000m² of hard standing at its first dedicated mortar plant using Vögele's most powerful wheeled paver. The plant in Brownstown, County Kildare, will produce a variety of mortars, including bagged products, for distribution throughout Ireland. The Vögele 1803-2 is one of four such machines operated by the company, and it complements a range of plant, including Hamm compaction

New technologies and new partnerships will heighten the rivalry in the compaction sector, Mike Woof reports The competitive compaction equipment market is providing customers with a broad and growing array of innovative technologies and solutions. At the same time, many firms are looking to increase market share through reorganisation of their operations and developing new international partnerships. This sector of the equipment market is certainly now more competitive, with major brands like Bomag, Caterpi

Special applications require stringent quality control and with compaction machines a key part of the paving process, their contribution can be vital. A high quality finish has helped athletes breaking sporting records on the track at the Shanghai Stadium in China during this year's 2008 Summer Olympic Games. Built in 1997 the stadium has been the venue for numerous major sporting events prior to the Olympics, however its track was showing signs of wear and the local authorities decided that a full refurbis

For centuries Venetians had given in to the Adriatic Sea, learning to celebrate its unique challenges rather than trying to hold back its tides, but that is changing. Built on an archipelago of 118 islands, with over 150 canals and over 400 bridges connecting the islands, visitors and residents to the old lagoon city travel only by water or on foot: it is considered Europe's largest car-free urban area. So the sight of a state-of-the-art Caterpillar AP655D asphalt paver is unusual, but it is assisting in a

Tensar International’s TriAx design solution has been used in the sub-base for the 17.9km Gdansk bypass in Poland. TriAx is said to be helping to combat the differential settlement across the poor soil of the Wistula river delta and to minimise frost heave caused by Poland’s severe winters.
