Methods of ensuring ecological and sustainable drainage in an urban environment are discussed in a new guide being published as part of Hydro International's Engineering Nature's Way initiative. Co-authored by Professor Richard Ashley, of EcoFutures , Sue Illman, of Illman Young Landscape architects, and Alex Stephenson, Stormwater Director of Hydro International and chair of the British Water SuDS focus group, Sustainable Drainage Systems (SuDS) in the Urban Landscape looks at Ecosystems Services, Green In

Demand for geosynthetics in the United States alone is projected to increase 4.4% per year through to 2010 to more than 727 million m². Geosynthetics, used worldwide in the highway sector for strengthening, include geotextiles, geomembranes, geonets, geogrids, geosynthetic clay liners, preformed geocomposites, geocells and geofoams. The US advances will be fuelled by a recovery in nonbuilding construction. Additionally, geosynthetics will continue to increase their use in a wider range of applications

Wirtgen's new 120F milling machine has been developed from the 100F launched late last year. The two machines use the same basic chassis but the 120F is a more powerful mill that can handle wider cuts of up to 1.2m. Jeff Wylie is product manager for Wirtgen's milling machines in the US and explained that the machine comes with several new features. Power comes from a Cummins QSC diesel and this engine is rubber-mounted, to reduce vibration and noise. A variable speed cooling fan is fitted that senses engine

In Australia local authorities are facing increasing pressure to keep roads properly maintained while cutting costs at the same time. This presents a major problem, however two local authorities have begun using a novel solution to road maintenance and repairs, based around using the latest version of Caterpillar's RM300 rotary mixer.

Hy-Ten's new positional couplers are said to speed up site construction times by using reverse cut threads to link together both reinforcement bars by turning the sleeve in one direction. Richard Webster, director at Hy-Ten, said: "We launched our standard range of friction welded couplers just 12 months ago and the concept has been enthusiastically accepted by both engineers and contractors. The new positional couplers extend the application of this concept into areas where reinforcement bars are immovabl
