The Bangladeshi authorities are looking to boost investment in road maintenance and repairs.

The Australian Government is setting aside funds for a major road rebuilding programme in a bid to repair damage caused by recent flooding.

Construction equipment manufacturer BOMAG will have a special focus on milling machines and finishers, and will feature two product premieres: the new BOMAG BF 800 finisher (world premiere) and the sales launch of the BM 500/15 compact planer, plus milling drums for third party cold milling machines in the 500mm class.

The 5700C-Max unit from Power Curbers has now been used on a tricky shoulder widening job in New South Wales, Australia. The machine carried out the job close to Robertson in the Southern Highlands, about 1.5 hours drive to the south of Sydney. The job required the construction of a 200m long section of barrier, built to the requirements of the Roads and Traffic Authority (RTA). The contractor hand-formed the concrete shoulder as it was about 3m wide at the start and narrowed down to 1m at the end.

Upgrade and maintenance work for 11,578km of strategic non-national roads in Indonesia may receive funding from the country's Public Works Ministry.

Concrete overlays have a long history and proven success in the state of Iowa. Mitchell and Worth counties in north central Iowa have led the way. In the past three years, they have put down approximately 241km of 102mm concrete overlay. Concrete Foundations Inc. (CFI), based out of Hiawatha, Iowa, has slipformed almost 80km of the counties' overlays, including 45km this paving season near the town of Osage. CFI has slipformed most of the overlays with its GOMACO two-track GP-2600 paver. This season, the co

Guntert & Zimmerman is offering a new system of telescopic end sections for its concrete pavers, which allow contractors to change widths between pours. These are also said to meet tight smoothness specifications and allow a contractor to carry out width changes quickly.

Demand for concrete slipforming techniques is strong in several key expanding markets
