The bitumen industry needs to learn how to communicate with road owners, road users, and communities. This was one of the underlying themes to emerge from the Eurasphalt & Eurobitume 2016 Congress, held in the Czech capital Prague in June. Kristina Smith was there.
Engineering firm Ricardo is part way through a research programme to develop an advanced energy recovery system that can be integrated into an excavator’s hydraulic system. Known as the High Efficiency Excavator (HFX) project, the system uses a 5kg carbon fibre flywheel that is encased in a vacuum-sealed cartridge, which contributes to minimising friction. The flywheel is spun at speeds of up to 30,000rpm using a magnetic coupling, which is driven from a hydraulic motor. Power for the hydraulic motor comes

CECE covers all of the EC and is pushing hard for further investment in infrastructure construction as a means to revitalise the economy. “Our industry looks forward to the implementation of the right policies and incentives to nurture sustainable growth and jobs”, said Ralf Wezel, CECE secretary general. CECE and the European contractor’s association FIEC believe that investment in transport is essential for growth and jobs. To strengthen European competitiveness, delivery of this much needed investment mu
