A versatile solution has helped with a tricky project at the Grand Canyon in the US – Pierre Peltier When Intermountain Slurry Seal, a division of Granite Construction, submitted its bid in 2009 to repair roads and parking lots along the Grand Canyon’s North Rim, the company knew the job would come with challenges. The remote roads leading from Jacob’s Lake, Arizona, to the North Rim Lodge had deteriorated to a point that the Federal Highway Association’s (FHWA) Central Federal Lands (CFL) Highway Division

In the UK, Foster Contracting was part of the team that carried out road improvements to the main route along the historic promenade of the seaside town Great Yarmouth, in eastern England. The harshness of the sea environment coupled with traffic loading caused the road surface to deteriorate, leading to brittle cracking of the thin surface course and also reflective cracking from overlain service trenches and patches. The town centre was already undergoing a major regeneration and as part of this scheme, i

An EC-funded project aims to coordinate research on essential tyre/road interaction parameters. A competition will help raise awareness of the project Drivers need grip between the tyres and the road to accelerate, decelerate or change the direction of a moving road vehicle. Grip is provided by the skid resistance properties of the road surface in combination with the friction characteristics of the tyre. This combination is critical for safe driving, and many European countries have investigated the corre

Automatic 3D machine guidance is a highly sophisticated area and a high level of expertise is often required to ensure applications of the advanced technologies work as desired. Fugro is a specialist firm that has gained experience using 3D guidance tools over many years and for certain tricky projects, Hexagon, the parent of Leica Geosystems, has turned to Fugro for assistance. For one difficult job in particular, Fugro's specialists were brought in at the request of an Icelandic contractor. The project ca

Melbourne winters are known as some of the coldest of all state capital cities on Australia's mainland, and its summers can be brutally hot. As a result, roads in the region need to be regularly maintained to ensure safety and promote longevity. Pioneer Road Services, headquartered in Victoria, recently took delivery of the first Cat AP300 asphalt paver to Australia, and it will be the first to play a role in maintaining the city's roads throughout the seasons. With the help of Cat dealer William Adams and

IRF has created a new Task Force on Pavement Preservation/Road Asset Management during its inaugural Executive Seminar on Pavement Preservation. The new task force's first meeting on 6 August, 2009 was chaired by Dr. Carlos Chang of the University of Texas-El Paso (UTEP) and 16 international delegates from various sectors of the road industry participated.

German company WEIRO has helped to introduce new microsurfacing technology to Estonia to upgrade its roads Estonia's rapidly growing road network requires modern and cost effective road surface rehabilitation technologies. As a result of technological and economical evaluations of the Estonian road network, it has been stated that repairs and upgrading of the existing network will remain the first priority, especially the repair of ruts, which represent a major problem in Estonia. The aim of a trial run of

Special reinforcements can extend the life of an old or new road, and also offer environmental benefits. Patrick Smith reports. Asphalt reinforcement can extend the service life of a resurfaced road by a factor of 3-4, says Huesker, developers of the HaTelit range of asphalt reinforcement. Aimed at preventing the propagation of reflective cracking from an old asphalt layer through a new surface course, Huesker claims the formation of reflective cracking is considerably delayed or even completely prevented u
