Choosing the correct high performance binder material for use in asphalt applications has been made easier following a product rebranding exercise by one company. Awareness among highway maintenance contractors of the benefits of selecting polymer modified bitumens when specifying road surfacing materials has risen markedly in the last few years.

Soil compaction BOMAG is pushing technological boundaries in the soil compaction sector with the market introduction of its giant 32tonne machines, which was shown in prototype/concept form at bauma in 2007. According to the firm the concept model attracted considerable interest and the company opted to develop the unit for series production. The new BW332 single drum roller is now the heaviest such machine on the market.

A lane separation system from Pexco is guiding more than 6,000 vehicles each day through changing traffic patterns.

The new ZRM 6014 road marking retroreflectometer from Zehntner is said to incorporate five innovations in one go: telescope handle and wheels as standard, colour touch display, camera, level meter and compass.

Using the latest paving technology has allowed contractors to carry out difficult projects Contractors in Germany and Italy have been able to carry out very difficult asphalt paving applications, using the latest machines from Vögele and Volvo Construction Equipment respectively. In both instances these projects benefited greatly from the use of the latest generation equipment and it is debatable as to whether such high quality results could have been achieved with older machines.

Road markings and raised pavements markers (RPMs) are important tools in securing efficient and safe traffic flow, and the high visibility of both is an important task in road maintenance, says DELTA.

High performance markings are among the safety products used to guide traffic safely, but they must be tested and checked. Patrick Smith reports. Road construction zones, zebra crossings, tunnels and areas with frequent fog are particular focal points with regard to road user safety. This is why manufacturers, authorities and contractors are always eager to use innovative road markings and special studs or, where necessary, lane control devices to assist both drivers and pedestrians in all conditions, parti

This year has seen a wide array of innovative additions to the asphalt paving market - Mike Woof reports. The worldwide asphalt paving market is both competitive and complex, with an array of important players jostling for position. At the same time, paving controls have taken a great leap forward with the development of accurate 3D systems that can use a combination of laser and GPS positioning. Leica Geosystems, Topcon and Trimble have all introduced new packages for the asphalt paving sector and these

Both soil and asphalt compaction technologies will see key advances in 2010, writes Mike Woof. With each phase of regulations coming into force for engine and noise emissions, as well as operator vibration, manufacturers have been forced to improve, upgrade and update their compaction machines.

Trimble is widening its portfolio of Connected Site survey solutions for the field and office. These upgraded tools allow surveyors to collect, share and deliver data faster to improve accuracy, efficiency and productivity.
