Asphalt milling, paving & compaction

New milling machinery at the recent Intermat exhibition will meet demands for customers wanting a range of machines stretching from compact units for road repairs to highway-class equipment for large resurfacing projects

CompLogger, a new hand-held compaction control system is being introduced by Dynapac as a soil compaction analyser. It provides a real-time image of compaction over the entire surface to be compacted. The easy-to-use unit can be used for production planning and throughout compaction and the data can also be saved for future quality control and evaluation.

In Germany a high production paving operation has been achieved using the largest machine available on the market. This project is all the more notable as the operation has been carried out in a continuous process, without joints. The Vögele SUPER 3000-2 paver was able to advance continuously at a rate of almost 4m/min. The machine was preceded by a bustle of activity, for no fewer than 24 feed lorries were needed to ensure an uninterrupted supply of mix to the paver, which placed an even asphalt surfacing

Sany’s new SAP90EC paver comes with large conveyor, augers and hopper to ensure consistent material delivery. A sophisticated hydraulic management system is said to improve working efficiency by 30%, while the machine is driven by an efficient and economical Deutz diesel, featuring advanced noise reduction and heat radiation systems. The latter allows the machine to be operated continuously in ambient temperatures of up to 50°C. The large hopper offers a capacity of 8.5m3 and this 24tonne machine can be use

Two Volvo ABG7820 slope pavers are being used to refurbish a 2,000,000m3 reservoir in Hieflau Styria, Austria. The machines are paving an extra high bitumen content asphalt that is watertight and have been modified to cope with the 34° embankments. The pavers were supplied by the Swiss dealer Robert Aebi and the modifications include tiltadjustable operating platforms to boost operator safety and comfort on the slope. The pavers are being operated by Walo Bertschinger, a Swiss company with a specialist dam

Caterpillar Phoenix-Zeppelin has delivered an AP555E paver to contractor USK Mnichovo Hradišt in the Czech Republic. The machine weighs in at 16tonnes and paves at up to 25m/min and is now working at a construction site near Brandýs nad Labem in the Central Bohemian Region. This versatile machine is able to pave using all standard types of asphalt mixes both in and outside urban areas. The Cat AP555E is also suited for the construction of major trunk roads or highways, while the fitting of a Trimble levelli

Improved infrared asphalt repair technology is speeding pothole repairs in applications in North America.

MeadWestvaco (MWV) says that its Evotherm warm mix asphalt technology is now approved by the Colorado Department of Transportation (Colorado DOT) for use in statewide paving projects. The warm mix asphalt system can be used in any traditional hot-mix asphalt application, but with significantly lower temperatures required for paving application. This feature is particularly useful in Colorado's high altitude paving projects and has been tested extensively.

US style high production pavers are seeing key performance gains - Mike Woof reports. Exhaust emissions regulations and ever tougher safety requirements have pushed manufacturers to develop new and improved pavers aimed at the US market. The rivalry between manufacturers of these machines has also intensified. European manufacturers have developed their own US style pavers in recent years. BOMAG, Dynapac and Vögele have all designed machines using the benefit of their US engineering input in a bid to target

A north German paving contractor is now relying on Vögele pavers for all of its operation. Gröschler is a group of four construction companies in northern Germany. The jobs Gröschler undertake for their customers range from narrow cycle paths to wide highways and it now has six Vögele pavers in its fleet, the tracked SUPER 1300-2, SUPER 1600-2, SUPER 1800-2 and SUPER 1900-2 pavers, as well as two wheeled SUPER 1603-2 and SUPER 1803-2 pavers. One job took the Gröschler team to Versmold, 30km west of Bielefel
