The concrete road sector looks to benefit from some key innovations and developments now coming to market or being employed in different territories. Irregular weather and environmental conditions can alter the rate at which concrete cures, with a risk of plastic shrinkage cracks that can compromise the integrity of a pavement. Contractors cannot control the environmental conditions of a paving project and when weather patter

    Concrete barriers offer a highway safety solution - Mike Woof writes. Concrete safety barriers are being installed on many of Europe's major highways, particularly for use as centre lane dividers. The strength and durability of concrete barriers can help reduce the risk of cross over accidents, one of several topics raised at a conference in Brussels on concrete highway barriers organised by the European Concrete Paving Association, EUPAVE. The conference was opened by Yves Deceoene of the IRF's Belgian ex
