Hamm is now offering a wider range of compaction machines featuring oscillation systems than ever before. These are available in a wide array of asphalt (and soil) compaction size classes, with 30 models offered to suit an array of different site requirements. The firm developed its first compactor with oscillation instead of vibration 35 years ago and machines with this feature now account for 25% of production.

Intelligent Compaction Measurement Values – ICMV – can be difficult to understand. What’s more, there is a lack of systematic and comprehensive documents explaining ICMV. For these reasons, the Federal Highway Administration (FHWA) and pavement engineering firm Transtec Group have released a technical brief to demystify ICMV. ICMV is a generic term for advanced measurement systems instrumented on vibratory rollers as a key components of intelligent compaction (IC) systems. It is based on the acceleration

UK Contractor Elm Surfacing recently carried out a milling and repaving job in Brixton in London. The job was carried out on Brixton Water Lane, with the firm using Wirtgen milling machines to remove the top layers of asphalt from the road surface. Repaving was then carried out using a Vögele asphalt paver, with a large twin drum roller then being used to compact the surface. Asphalt paving was carried out in two layers, replacing the binder course and wearing course, although the original base course was l

Spanning nearly 200m, the new bridge includes four lanes for highway traffic, a pedestrian underpass, and other concrete flatwork that is expected to improve traffic flow and road safety.

The pace of development continues in the soil compaction sector, with key firms rolling out new machines - Mike Woof reports. New soil compaction technology is now being offered by several key manufacturers. Improved machines and new systems to boost performance are being offered by various firms. From BOMAG comes the availability of its Economizer system for its soil compactors. The technology has been well-proven in the BOMAG twin drum asphalt compactors as well as on the reversible plates and trench c

UK contractor Amey said it has successfully conducted trials of wearable biometric and location device safety technology that could reduce risks to drivers and lone workers. The technology was provided by Fujitsu. It included a collar drowsiness detector and ear clip, measuring changes in blood flow which are indicators of attention loss and an initial sign of fatigue. The small units detect when the body is under stress and help workers raise instant alarms at the touch of a button.
