German firm Wirtgen is retaining its lead in road recycling technologies – Mike Woof writes Tests on cold recycling with a new layer thickness using Wirtgen's sophisticated WR 4200 machine have shown impressive results according to the firm. The road construction and traffic authority Landesbetrieb Mobilität (LBM) Cochem-Koblenz commissioned a pilot project as part of its plan to optimise the cold in-place recycling process (CIR). The aim was to examine the extent to which the layer thickness can be reduced

The latest asphalt testing equipment brought onto the market is both innovative and highly accurate as Kristina Smith reports Advanced pavement design requires advanced test equipment. And advanced test equipment takes time and money to design, engineer and produce. But if your expensive testing machine could perform a few more tricks, buying one would make financial sense to more organisations. This is the thinking behind IPC Global’s new Uniaxial Fatigue Test Kit for its Asphalt Performance Mixer Tes

When it was completed in 1965 – just six years after the Auckland Harbour Bridge – the six-lane Newmarket Viaduct with its tall, slender piers was something of an engineering wonder, the first of its kind in the Southern Hemisphere. Forty years on it had become a much-maligned contributor to Auckland’s chronic traffic congestion, too weak seismically to withstand the heaviest loaded trucks let alone a severe earthquake, so narrow in the shoulders that any accident stopped traffic flow and made it difficult

Engineering firm Exergia completes vital communication route using innovative construction methodology. The devastation caused by a 35-year armed conflict has led to a high state of degradation of Angola’s network of roads and bridges, presenting a significant impediment to the country’s recovery. In 2002, the Government of Angola created an extensive rehabilitation and reconstruction program of the road system. As part of this program, the rehabilitation of National Highway 120, the main road linking
