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

By this spring, Bomag’s new BM 2200/75 cold planer will have removed all the old pavement from a 2.6km section of Germany’s federal highway B-85.

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

Instarmac’s UltraScape Flowpoint grouting has been installed at three new roundabouts and road edges in the Estonian capital Tallinin.

Construction of Juuliku Road Junction and Road Section involved reconstructing areas of the existing road network as well as introducing a 3.4km connection road, two bridges and viaducts and a two-level interchange. An additional three roundabouts were built wit
