Asphalt milling, paving & compaction

Advanced road recycling capabilities are offered by Wirtgen. Having started as a contractor, Wirtgen’s roots in this side of the business are strong and the company’s development of road recycling systems has become a core competence, originating as an offshoot of its contract work. Wirtgen’s leading position in the milling machine market continues and although an increasing number of rival firms offer machines, the company’s share of this segment remains dominant. With demand for machines having grown in 2

Cold mix road repair material containing 100% recycled asphalt has been laid on rural routes in northWales, UK, by the contractor Hogan Construction.Work was carried out to demonstrate that structural integrity can be restored to a failing carriageway without making use of primary aggregates or hot bitumen.

Stirling Lloyd is using innovative micro-trenching technology during a £1.1million (US$1.72million) project to improve Internet infrastructure on the Shetland Isles off the north-east Scottish coast.

Equipment for checking out the various qualities required of asphalt in road construction is becoming more sophisticated

High quality standards and high quality equipment have led to one company building a strong market share in a part of the US with high requirements on finish. The Pavement Maintenance Division of American Asphalt and Grading is based in Las Vegas, Nevada, but is highly active right across the states of California, Utah, Nevada and Arizona. This operation is run by Eric Reimschiissel and was established as a division from the parent company in 2001 and has since grown to have two paving/patching crews, two s

Compact compaction units are delivering increased performance – Mike Woof reports. Competition is tough in the market for non-ride-on compaction units, with two manufacturers now introducing revamped models. Both JCB and Wacker Neuson aim to claim a larger section of the market with their latest designs, compaction plates and remote-controlled trench rollers respectively.

The Wirtgen Group is developing its manufacturing facilities outside of Germany. The company has extensive operations in Brazil and China and has now opened a new plant in India, which has started production already. Joint president Stefan Wirtgen said, “The first machine we made was a Hamm compactor. It is specially developed for the Indian market.”

New machines are now coming to the international market, with Chinese firms producing a particularly strong showing. At the last BICES exhibition in Chinese capital Beijing, one of the most notable developments was how many of the country’s equipment manufacturers now offer ranges of soil compaction and/or asphalt compaction equipment.

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.

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.
