Study aims to improve fuel economy by up to 30 per cent

March 20, 2012

A US$1.2 million three-year research project, one of the first major US studies to focus on 'eco-driving' techniques, conducted by the Center for Environmental Research and Technology at the University of California, Riverside, is aimed at the development of a next-generation, environmentally friendly driving feedback system with the goal of generating fuel savings of between 10 and 30 per cent. The project is being funded by a US Department of Energy grant, which is part of a $175 million federal programme

Asphalt milling machine gives a fine finish

March 20, 2012

High micro-milling results are said to be achievable using the new cutter from Roadtec. This product has been developed to meet the growing demand for thinner friction courses, which require proper surface preparation. Delamination of thin courses can occur when surfaces are prepared with conventional milling equipment, according to Roadtec. The firm adds that water can get trapped in the recesses of a conventionally milled surface, leading to premature pavement failure.

On the spot pothole repairs

March 20, 2012

Phoenix Industries says its new equipment can deliver on-the-spot pothole repairs even in the toughest winter climates. The MP 300 is a truck or trailer-mounted mobile patching unit which utilises PelletPATCH, an innovative rubber modified pellet material for pothole patching. Phoenix, who have a sales and service agreement with M-B Companies, claims this allows for permanent roadside pothole repairs.

Versatile snow clearing machines

From removing light snow from pavements and driveways, to shifting heavy or packed piles of snow and ice, Bobcat claims they have tools for any winter job. Different hydraulic motor packages now come with the company’s snow blower models, which offer widths varying from 1,220mm to 2,134mm. With throw distances from 7.6m to 13.7m, the models have a rotating chute and deflector to point the snow in the preferred direction.

Precision narrows the gap between design software and GIS

March 20, 2012

Greater precision is helping blur the boundaries between GIS technology and design software While GIS map based technology has extended its range across an ever more universal spectrum of uses in the highways sector, it is increasingly showing weaknesses for engineering purposes. It is very often not accurate enough. This has not mattered previously because the GIS tool has been seen essentially as an automated version of paper based systems from the design department's point of view. Where engineers

Innovative utilities approach

March 20, 2012

An innovative approach to the management of utilities works is the result of a partnership that has produced the Intelligent Trench. This novel underground mapping solution is also being combined with PelicanCorp's beforeUdig service to deliver a comprehensive and accurate national record-sharing service for underground assets in the UK. The new no-charge service allows local authorities and contractors to use the Intelligent Trench portal to access utility plan information directly from the portal's data b

Wireless remote control a key feature of new concrete pavers

March 20, 2012

Slipform paver manufacturers are currently seeing strong business gains, Mike Woof reports The concrete slipforming sector is seeing strong business gains at present, with high demand for machines right around the globe. In Europe and the US, barrier machines are in particular demand, while in Russia airport paving is top of the agenda. All over the world, airports have to be rebuilt to cope with new large aircraft, and machines are busy operating in Asia, Europe and both North and South America on this

New functionality for infrasfructure design software

March 20, 2012

Chris Bradshaw, Autodesk's vice-president for the Infrastructure Solutions division spoke to World Highways. The launch of the fourth version of its Civil 3D design software early this year will see software maker Autodesk getting serious about its road and general civil engineering package. Bigger projects can be handled in the 2008 version, and a range of new functionality is being added. "Though not everything we would like yet," said Chris Bradshaw, Autodesk's vicepresident for the Infrastructure S

Award-winning road and bridge design software

March 20, 2012

The integration of software tools, users and data was an important factor in a major highway project The giant High Five interchange in Texas, USA, emerged as a key winner in Bentley Systems' software awards this year. It won both the Innovation in Road and Bridge category and, significantly, Connecting Project Teams. The awards, a feature of the annual exhibition/conference organised by the software house, attract increasing interest from industry, and competition has become widespread, not least bec
