Effective compaction control is one of a series of technical innovations boosting performance efficiency – Mike Woof writes. Maximising compaction efficiency can be a major cost factor on construction projects. Both for soil and asphalt compaction sectors, the risk from leaving an area under or over-compacted is substantial.

The Los Angeles County Metropolitan Transportation Authority (Metro) has approved the selection of HDR to perform the I-710 Corridor Project North Utility study.

German Transport Minister Peter Ramsauer has announced that the government is currently preparing to invite tenders from companies and consortia throughout Europe for the collection of Germany’s truck toll scheme,

Boomerang Systems, a designer and manufacturer of automated robotic parking and self-storage systems, has been contracted to supply 249 parking spaces utilising its RoboticValet parking system in the Metropolitan Project in Atlantic City,

The ongoing Highways Agency A66 Carkin Moor to Scotch Corner project involves upgrading the original single carriageway to address safety concerns, particularly at junctions and crossings. Where differential settlement is threatening a remodelled junction, Tensar International's new TriAx geogrid provides an additional dimension of stability, saving design and build contractors Balfour Beatty Regional Civil Engineering Limited (BBRCEL) the heavy time and costs inherent in conventional remedial solutions and

World of Asphalt 2012 and the co-located AGG1 Aggregates Forum & Expo will be the largest in the history of the two events. Guy Woodford reports on some of the technology and equipment set to be on show. With over 6,500m² of exhibit space available, World of Asphalt 2012 (WoA) is among the global showpiece events of the year for all asphalt, pavement maintenance and traffic safety industry professionals.

Tensar is making some key moves internationally, as well as in terms of market segments. The company is now marketing the GlasGrid range in the US and expects to develop healthy sales, however it sees major growth potential with the Geogrid product range. Jim Penman, director for bi-axial products & applications said: "One area we're moving into is base reinforcement and in particular what we're looking at is mechanistic emirical (ME) technology." Tensar has worked with the University of Illinois on a new d

The US$2.23billion (€1.7billion) contract to build the Pedemontana Lombarda motorway in northern Italy has been won by the Strabag consortium.

The latest IRF Bulletin is wholly devoted to issues of Environment & Climate Change as they impact on the road infrastructure sector. It features an authoritative but highly readable set of articles contributed by IRF members throughout the world.

*Susanna Zammataro introduces the range of issues addressed by IRF Geneva’s very active Environment Committee. Achieving sound environmental and sustainability outcomes has long been an integral part of IRF members’ policy and practice.

Using geosynthetics for soil reinforcement is highly effective but requires a high quality and trusted geogrid. When it comes to deciding which geogrid is best for a specific project, a number of product parameters must be taken into account. In the design of steep slopes, the most important parameter is the available long term design strength (Pdes). Recently, Colbond has significantly increased this factor for its high performance Enkagrid product, recognised with a newly updated BBA (British Board of Ag

Rural roads in developing nations can feature all kinds of hazards.

Trimble has launched a range of new tools which it says will deliver faster and more accurate data to surveyors. The Trimble S6 Robotic Total Station with Trimble Vision Technology enables surveyors to remotely see and measure through a live video feed from the instrument on their data controller.

Roadsigns are required to give clear directions.

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.

High performance cycling and mowing capabilities are claimed for this newly developed system designed in the UK.

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.
