Cut and cover consolidation

July 10, 2012

Foundation specialist Forasol has developed an innovative technique for anchor drilling that is improving ground consolidation on road projects in Switzerland. The technique has been widely used on a number of highway projects in the country, including construction of a new 1.3km long cut-and-cover trench for the A9 highway in south western Switzerland.

We have the technology

July 10, 2012

'Le Barbare' or The Barbarian, the biggest wheel loader in the Caterpillar range, had already clocked up a respected 48,000 hours of heavy duty in the Belgian quarry Carrieres d'Antoing when a need for a bit of rejuvenation was identified. To carry out this careful operation, the local Caterpillar dealer Bergerat Monnoyeur tore the impressive 193tonne 994D wheel loader into thousands of pieces, reworked them all and then reassembled the whole machine with new or refreshed parts: it performed a full rebuild

Ringway expands ABG fleet

July 10, 2012

UK highway maintenance contractor Ringway has expanded its ABG paver fleet to 15 in all, with the addition of another Volvo 6870 wheeled paver. The ABG6870 is the latest in a long line of ABG machines to be used by Ringway, which also has a number of 273 and 473 machines. The new machine will be used for a wide variety of jobs by Ringway, who specialises in handling contracts for local authorities. Already the machine has been out on resurfacing contracts with the London Borough of Enfield and further north

Swiss mini-motorways made bigger

July 10, 2012

Widening the busy A4 road in Switzerland to four lanes was achieved quickly by using the latest paving technology. Increased traffic required the widening of the A4 from two to four lanes along a 20km section, with two lanes separated by a central divider in each direction. Carrying 20,000-25,000 vehicles/day, the trunk road between Winterthur and Schaffhausen was one of Switzerland's busiest two-lane stretches, and as a result, the Federal Council of Switzerland in Bern planned an enlargement of the dual-l

Crushing performance

July 10, 2012

High productivity and performance are claimed by Sandvik for its innovative UH421 mobile secondary crushing unit. This crusher is designed to deliver a continuous flow of high grade material and features a new, high capacity screen that allows high output. A novel feature is that the screen lies alongside the crusher while the design slows down and spreads out the material as it reaches the screen area. In tests the Sandvik SS screen was able to produce material containing no fines, despite dry conditions.

Faster cutting

July 10, 2012

Trencher firm Mastenbroek says its 20/14 rock trencher is aimed at the utility equipment and highway drainage markets. The machine shares proven features with existing chain trenchers from the firm such as the 10/12 model and is powered by an emissions compliant Cummins diesel rated at 164kW. The machine features as standard a trench unit that can be offset to the left or right and drive to the chain is hydrostatic through a direct coupled, independent low speed, high torque motor. The heavy-duty chain can

Milling machine cutter options

July 10, 2012

Kennametal says that its latest cutter technology offers greater life in hard trenching, milling and extraction applications, while it is also able to offer purpose-built milling drums to suit specific applications. The new MTB1 trenching and MTB2S surface mining tool blocks are offered in long and short body styles and are said to be harder, stronger and easier to use than the firm's earlier TH3 line. The larger, heavy-duty barrel provides rigidity and durability during chain trenching and surface mining.

Safety rallying call to English councillors after road death rise

July 9, 2012

English councils have been urged to protect the public on the roads by “whatever means is appropriate” after the first rise in road deaths in the country for eight years. Professor Stephen Glaister, director of the RAC Foundation, said data obtained by the Foundation under the Freedom of Information Act (FOI) showed there had been “no mass switch off” of speed cameras in England despite two years of Government road safety funding cuts. But Glaister fears an ageing national network of existing speed camera

Accurate speed monitoring

July 9, 2012

The new generation SPECS3 average speed enforcement system offers key improvements over earlier generation units. This package is said to help reduce congestion, emissions and achieve high speed compliance rates, boosting traffic safety. The system has now successfully completed the technical testing phase for the UK's Home Office Type Approval (HOTA) and looks likely to be accepted in other European countries. It has been recommended for full HOTA by the Roads Policing Enforcement Technology (RPET) committ

Building Spain's highest viaduct

July 9, 2012

Amid a mountain wilderness, a new highway system rises, featuring Spain's highest viaduct For years, motorists and truck drivers in northern Spain have had to endure using a dangerous road liable to traffic hold-ups, delays and accidents, and frequently impassable in the depths of winter. In any event it is a slow and tortuous climb from Molledo on the Cantabrian lowlands up the N-611 road through the Cantabrian Mountains to Palencia, on the Meseta, Spain's high central plateau.
