Asphalt paving improves road safety

A special emulsion is being used at the largest gold mine in South America for slurry surfacing on its compacted, unpaved roads. The result is said to be greatly curtailed particulate emissions and enhanced visibility which makes roads safer and reduces regional haze.

Drain protection pads provide temporary seal

UltraTech International has produced a range of transparent covered drain protection pads, which the company says will end guesswork over drain seal effectiveness. The pads enable contractors to swiftly establish if spills are entering the drain through cracks in the surface, imperfections in the grating, or other irregularities that can break the seal.

Smart paver control solution provides optimum materials mix

VSS Macropaver reports a strong sales performance, with exports having been particularly profitable for the company, write Mike Woof. Vice president Doug Hogue said: "We're fortunate that we're dealing on a world basis to Latin America, China and Russia." Latin America, Chile, Mexico and Peru have been key markets for the firm, although the high import tariffs into Brazil have unfortunately meant that the company finds it hard to compete in this country's strong road sector against local rivals.

Lightweight composite manhole covers

Composite rather than metal manhole covers are better for the UK road network, according to a recent technical paper by distinguished chartered engineer John Newton. In his paper Mr Newton, inventor of the composite manhole cover, claims tests have proved a new generation of innovative composite covers, developed and manufactured by Barrow-in-Furness-based Structural Science Composites (SSC), outperform ductile iron manhole covers, while also offering better value for money.

China's economic growth fuelling vehicle increase

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.

Hydrocarbon resin bitumen modifier enhances adhesion

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. However whether this big Cat lost one of its nine lives in the process remains to be seen.

Asphalt paving developments

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
