The Echline road construction project using sustainable design and construction techniques

摘要

The Scottish Executive Development Department, Trunk Roads - Design & Construction Division have funded the construction and testing of a trial section of experimental road pavement at Echline, South Queensferry, Edinburgh. The trial completed in April 2000, had a clear objective to maximise the use of sustainable, in-situ, recycled and cold lay materials and minimise the overall construction energy requirements. The trial site will not receive traffic in the short to medium term, however the project has demonstrated that all the materials used can be manufactured and laid in a controlled manner. Over the first year the in-situ performance has been monitored with encouraging results, in keeping with that which would be expected based on previous experience. This paper will review the materials used in a flexible composite pavement design, the material production and pavement construction process and outline the testing regime in place to validate performance.
