||Local authorities are responsible for some 98 per cent of the road network in England and Wales and for a large percentage of roads in Scotland and Northern Ireland also. This includes a wide range of roads, from heavily trafficked principal roads to lightly trafficked rural lanes and suburban estate roads.Highway maintenance and new construction has a massive part to play in the sustainability debate. By focusing on recycling arising from the existing road, using imported, recycled or secondary aggregates where appropriate, and choosing techniques that minimise the production of greenhouse gases, local authorities and highway engineers can work positively with the environment and have a major impact on sustainability targets."Sustainable Highways: A Short Guide" provides helpful advice for local authority highway and material engineers on the choice of sustainable materials and techniques for use in highway and footway maintenance as well as new construction. "Sustainable Highways: A Short Guide" is issued as a partner publication to "Well-maintained Highways: Code of Practice for Maintenance Management" (ISBN 9780115526435, available below).The chapters include: Sustainable Construction; Linking to Corporate Objectives; How to Build a Sustainable Road; Materials, Methods and Milestones; Key Performance Indicators and Sustainability Index; Specifications and Quality Control; Environmental Impacts; Waste Management Regulations; Measuring Sustainability; and, Climate Change.
