More than ever, demands are being placed on the highway community to findhigh-quality materials to restore highways. With concern at the pace at which virgin aggregate is being used in some regions, such as Europe, recycling has added urgency. Governments and local authorities are constantly looking for more sustainable construction methods which protect much-neededenvironmental resources for the benefit of future generations. In the UK,an analysis of the growth potential for recycled and secondary aggregate use in asphalt over the next 10 years indicates that around 14% of primaryaggregates could be replaced by secondary alternatives, generating considerable cost savings. This special supplement has a two-fold purpose: to remind the industry of the need to push the case for recycling given the lack of primary quality aggregate and possible legislation restricting its use, and to impress on governments, NGOs and others of the progress being made by the stakeholders in the roads sector - and that it is responsive to the needs of the environment.
