Asphalt milling, paving & compaction

A new online concrete pavement design tool has been launched in the US by three major cement and concrete organisations. PavementDesigner.org – available free of charge - was created for city, county, and consultant engineers as well as academics and anyone involved in design of roadway, industrial, and parking area pavements. PavementDesigner improves upon traditional pavement design software programs, according to its creators. The platform is being offered completely free of charge by the American

Bomag is now fitting its compact roller in the 3-5tonne class with dual amplitudes.

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

Finland’s main international airport, serving the capital Helsinki, is now benefiting from a runway resurfacing project. The rehabilitation work has been needed for one of the airport’s three runways due to a number of age-related defects. Helsinki Airport processes some 17 million passengers/year and due to a combination of the often severe winter weather and the heavy aircraft traffic, the runway condition was not of the standard required. Resurfacing work was scheduled by FINAVIA, with a budget of some

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

Asphalt paving is a challenge in the rough terrain of the Swiss Alps and nowhere more so than in the mountain village of Castiel. Extreme slopes, narrow roads and steep precipices place demands on the paving team and machinery. In the town of Castiel, in the Arosa district of the canton Graubünden, contractor HEW Bauunternehmung opted to use Vögele’s Super 1803-3i wheeled paver for rehabilitation of the combined base and surface course on a farm track. The site is around 1,200m above sea level and an

Formwork from Doka is playing a key role in constructing the airport’s buildings. At times as many as 80 cranes will be in use. Two-thirds of the formwork for the first construction phase are supplied by Austrian experts for formwork solutions, Doka. On this build the Doka engineers are combining in particular Timber formwork beams H20 eco and H20 top and load-bearing towers, plus Framed formwork Framax Xlife and Frami Xlife and Large-area formwork Top 50. The formwork systems from Doka are in use in many a
