German company WEIRO has helped to introduce new microsurfacing technology to Estonia to upgrade its roads Estonia's rapidly growing road network requires modern and cost effective road surface rehabilitation technologies. As a result of technological and economical evaluations of the Estonian road network, it has been stated that repairs and upgrading of the existing network will remain the first priority, especially the repair of ruts, which represent a major problem in Estonia. The aim of a trial run of

In Brazil, concrete pavers from Wirtgen are being used to improve sections of the BR-101 highway as well as to construct concrete safety barriers. The use of these machines is of note as it is the first time concrete paving has been used on a federal road in Brazil. The 1st Army Engineering Division of the Brazilian Army is carrying out three of the eight North Eastern sections, as the construction work had to be speeded up project because the road is deemed crucial to the country's economy. Two Wirtgen SP8

Concrete paving machines from Guntert & Zimmerman have been carrying out important surface repair jobs around the world. In Belgium a paver from the firm recently completed a high speed road repair, while at Qatar's New Doha International airport one of the firm's S850 units has carried out a major apron paving contract. The new airport is being designed to cope with large passenger aircraft such as the Airbus A380 and the Sinohydro-Gamuda-WCT joint venture was awarded the contract to build two runways, thr

The latest technology continues to improve the quality of concrete paving while contractors are also benefiting from more adaptable equipment - Mike Woof reports For many concrete paving applications, versatility is required rather than a high production rate. Leading paver manufacturers such as GOMACO, Power Curbers, Terex and Wirtgen all offer high mobility machines that can be adjusted to cope with an array of tasks. For a contractor, the advantage of these smaller pavers is that they can be configured q

GPS systems for machine control can make massive reductions in operating costs for contractors. Using GPS systems for machine control can make massive reductions in operating costs for contractors and the pace of technology improvements from manufacturers has been rapid. This market segment is dominated by Leica Geosystems, Trimble and Topcon, all of which introduced an array of new products earlier this year. Topcon's dozer control system first seen in public at the Intermat show in Paris, offers notable c

One company has produced eight asphalt plants for a major project, and others are introducing new models as Patrick Smith reports Algeria's US$11.2 billion East-West Highway development, the world's largest current highway construction project, forms part of the larger Trans-Maghreb Motorway project, and is scheduled for completion in 2010. It will run for 1,216km, ensuring the link between Annaba in the north-east and Tlemcen in the north-west, passing directly through 24 provinces and linking Algeria to T

With the launch of its innovative D7E diesel-electric bulldozer, Caterpillar has shaken up this traditionally conservative market Only rarely do product innovations come to market that can truly be described as groundbreaking, but Caterpillar's D7E fits that bill. To understand the giant leap that the D7E represents, it is important to recognise Caterpillar's long history in the bulldozer market, which is unmatched by any of its rivals. Caterpillar pioneered the crawler track with founder, Ben Holt, havin
