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.
This paper outlines the energy consumption data for each material installed in the road trial including aggregate and binder processing and final product mixing. A comparison is made between the construction energy requirements for the ‘alternative recycled’ pavement and that for a conventional pavement deemed to have similar design life. The environmental benefits of using recycled and industrial by-product materials in road construction are highlighted.
