The work of Echo Barrier was highlighted at a prestigious Institute of Acoustics (IOA) sponsored awards ceremony held at the House of Commons. The company, which develops and supplies temporary acoustic barriers for use on major construction projects to reduce noise pollution, was highly commended for its Echo H1 barrier and range of products during the 2011 John Connell Awards.

China is at a turning point in many ways. The country's continuing economic growth is fuelling a massive increase in vehicle numbers, with no signs of slackening. This is most acute and most visible in major cities such as Beijing and Shanghai, where traffic jams are now a frequent occurrence. One recent Beijing tailback stretched nearly 100km along a major highway and was caused by roadworks at a particularly busy stretch of the road.

In Estonia, Novotrade Invest, which produces hydrocarbon resin HCR-105, has carried out research work on the material that can be used as a bitumen modifier. Hydrocarbon resin HCR-105 is obtained by thermal polymerisation of hydrocarbon fraction C9 [industrially it is isolated from the C9 aromatic hydrocarbon fraction during petroleum distillation].

A Caterpillar 730 ADT recently took to the air at a project in Switzerland and the 23tonne truck was carried to a site with restricted access in the Alps, using a specially adapted lifting assembly attached to the cable normally used for a cable car.

US and European asphalt paving needs are different, but some firms are bridging that gap, reports Mike Woof. With a clear differentiation between the US and European asphalt paving markets, manufacturers from the latter are now developing machines aimed at the former. The US and European markets for paving machines have developed along very different lines. North American pavers are designed for high throughputs and high paving rates, having been designed to meet a need to build roads over long distances wi
