Fast, cost-effective road stabilisation
The Kivikko industrial area in Finland, which is owned by the City of Helsinki, has expanded gradually over the years and it has expanded again with the new stabilised area now about 3.5hectares. The ALLU equipment and system was used to stabilise Kivikko for the first time in 2001, and the latest job started in June 2010 with the stabilisation work completed by mid-December 2010. [The ALLU Stabilisation System is a Finnish invention that provides a fast, cost-effective and environmental-friendly working
Turkey's infrastructure programme
The tender process for Turkey's third Bosphorus Bridge is due to commence on 23rd August 2011. The project will be built under the build-operate-transfer model. This forms part of a massive investment in infrastructure in Turkey.
Concrete barrier challenge
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.

Costa Rica concrete repairs
Work has started on the long awaited San Jose-Caldera Highway in Costa Rica, following numerous delays and setbacks. The new 77.5km highway will be used daily by more than 81,000 vehicles, reducing the travel time between the Central Valley and the Central Pacific Coast by at least 30 minutes.
Efficient concrete overlays
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
Service cover
Prolec is now offering a full service and maintenance agreement (FSMA) with an annual system inspection for its Liftwatch 5 systems. This package is intended to boost awareness of the need for system care and provide an annual Loler inspection for equipment ensuring all regulatory requirements are met.
Laos boosting roads
The authorities in Laos are planning a massive road and highway improvement programme. This new strategy from the Ministry of Public Works and Transport calls for a total of 1,151 road improvement projects, which will receive government investment worth US$14 billion.
Paving versatility
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.
Strong demand for concrete paving
Demand for concrete slipforming techniques is strong in several key expanding markets
Utility spec for JCB's 8018
A range of safety specific additions have been made to JCB's 8018 mini excavator after the company worked with leading utility contractors to develop a special industry-specific version of the machine. The largest of the three 801 minis, the 1.6tonne machine retains its digging capabilities and its powerful 14.2kW Tier III compliant motor, but the utility pack offers requested upgrades. For example, to prevent damage on site, the lower door window has been replaced by a steel panel and the rear counterweigh
INTERMAT launch for Ammann’s ARX roller models
Ammann is launching an extended range of lightweight tandem rollers, badged the ARX models. The range includes 13 models from 1.5-4.5tonnes and working widths from 820–1380mm, to replace the AVM-2 range later this year.
Caterpillar's milling and loading advances
Caterpillar is broadening the range of applications for its PM200 milling machines as well as offering a new tracked loader model. The PM200 milling machine can now be fitted with a 2.2m wide milling drum for special wide cutting applications.
China's massive bridge opens
The world's largest bridge over water is now open to traffic. Measuring over 42km long the bridge links China's eastern port city of Qingdao with Huangdao Island.
Improved consolidation
Upgrades to Dynapac's Racoon+ poker drive include rubber protection against shocks and prevent the drive unit's body from being in direct contact with dust, helping to protect the electric motor. This flex shaft concrete vibrator is a complete high frequency vibration system eminently suited for daily operation on small and medium sites for applications such as walls, floors and pre-cast fabrication.
Safety barriers deliver valuable road user protection
Safety barriers provide an invaluable service for all road users, Mike Woof reports The safety barrier market is a key one for the highway sector, with systems providing valuable protection for all categories of road users. The importance of passive protective devices such as safety barriers can often be overlooked by the road user but is well-understood by highway designers. Redirecting an errant vehicle back into the roadway and preventing it from crossing into traffic flowing in the other direction or fr
Compact machines deliver more - for less
The mini and midi excavator sector continues to squeeze more out of less, with some innovative engineering solutions being applied to zero- and short-tailswing models - Geoff Ashcroft investigates. It is a vicious circle - customers seek smaller, tighter, ever more compact excavators, leaving manufacturers with the challenges of squeezing greater levels of technology into what is all too often an even smaller machine.
Developments in road stabilisation machines
Road stabilisers play an important role for road recycling, with new machines coming to market - Mike Woof writes
The reclaimer/stabiliser is becoming a much more important machine in roadbuilding applications now that the construction market is increasing its use of road recycling. The reclaimer/stabiliser used to be a niche machine offered by specialist manufacturers such as CMI, which was a pioneer of the concept. However in recent years this type of machine has become an important construction tool,
