Airport runway, taxiway and parking areas make high demands on paving requirements, both with concrete and asphalt techniques. Mike Woof reports. High quality surface finishes are required in airport environments for runways, taxiways and aircraft parking areas. Because of the speed at which aircraft take off and land and the massive forces exerted due to the weight of the aircraft, particularly during landing, runway structures need to be incredibly strong. The surfaces also have to be constructed to very
Evonik has developed a simple but effective concept to reduce the risk of wrong-way drivers.
The company’s cold plastic, one-sided rumble strips have been developed following a string of incidents in Germany in which drivers have travelled in the wrong direction on stretches of high-speed autobahn. The marking system has undergone successful initial tests and the concept has been received well by German police, looking for a system to deal with the problem. There are around 75-80 crashes/ year in Germany
Rohit Baluja is a man with a mission, and that is to help reduce the grim accident toll on India's roads, the worst in the world. Baluja, a shoemaker by trade, has been studying for a PhD in civil engineering, and this has involved regular trips to Birmingham, UK, to complete his doctorate.
All this seems far removed from 18 years ago when in December 1991, using much of his own money, he founded the Institute of Road Traffic Education (IRTE), the only organisation in India that conducts accident investiga
This month’s bitumen technology pages bring you self-healing roads, slippery roads and slimmer roads and explains why one UK contractor has started manufacturing its own polymer modified bitumen - Kristina Smith reports. Professor Erik Schlangen, who heads up experimental micromechanics at the Delft University of Technology is receiving calls from all round the world these days. And it is hardly surprising because he and his team have invented a great new technology: asphalt that heals itself.
