Caterpillar Phoenix-Zeppelin has delivered an AP555E paver to contractor USK Mnichovo Hradišt in the Czech Republic. The machine weighs in at 16tonnes and paves at up to 25m/min and is now working at a construction site near Brandýs nad Labem in the Central Bohemian Region. This versatile machine is able to pave using all standard types of asphalt mixes both in and outside urban areas. The Cat AP555E is also suited for the construction of major trunk roads or highways, while the fitting of a Trimble levelli

MeadWestvaco (MWV) says that its Evotherm warm mix asphalt technology is now approved by the Colorado Department of Transportation (Colorado DOT) for use in statewide paving projects. The warm mix asphalt system can be used in any traditional hot-mix asphalt application, but with significantly lower temperatures required for paving application. This feature is particularly useful in Colorado's high altitude paving projects and has been tested extensively.

US style high production pavers are seeing key performance gains - Mike Woof reports. Exhaust emissions regulations and ever tougher safety requirements have pushed manufacturers to develop new and improved pavers aimed at the US market. The rivalry between manufacturers of these machines has also intensified. European manufacturers have developed their own US style pavers in recent years. BOMAG, Dynapac and Vögele have all designed machines using the benefit of their US engineering input in a bid to target

Sophisticated new paving technologies are coming to market that will help boost quality and performance. New paving technologies are being introduced to meet the differing demands of both North American and European customers. Although North American and European paving techniques do vary, there are also some control technologies being introduced that will help quality for both approaches.

Twin-layer paving offers high quality, long lasting road surfaces to be constructed. Paver manufacturer Dynapac is one of the pioneers of the twin-layer paving technique, which it calls Compactasphalt. According to Dynapac this method offers major benefits to contractors and clients alike as roads surfaced using this technique last longer and are cheaper to maintain. To ensure contractors have maximum utilisation of their machines, Dynapac offers a modular paver system that can be operated using the convent

Tony Pearce, honorary life member and former director-general of IRF Geneva, recalls the history of the Silk Roads, highlights their continued economic relevance and introduces IRF's active long-term commitment to their rehabilitation. The Silk Roads had their origins in a Chinese military mission in 138BC to purchase horses in Central Asia's Fergana Valley that were reputed to run so fast that they sweated blood. When General Chang Ch'ien reached Fergana, now in Uzbekistan, he found that the fabled horses
