Hirlestane Road is a street near the centre of the historic capital city of Edinburgh in Scotland. The street is old and is surfaced with granite stone setts. The road required reconstructing and upgrading. The pavement structure under the natural stone surface with the original roadway was soil. The upgrading required that a high performance pavement structure was formed under the stone setts and above the soil foundation. The original stone setts were to be cleaned and re-laid. The decision was made by the City of Edinburgh Council to rebuild the roadway using no new materials. The new pavement structure built in Thirlestane Road used cold emulsified asphalt technology. Asphalt plannings from maintenance operations within the City of Edinburgh were processed to create two materials that formed the sub-base and base to the re-built pavement structure. A lower strength sub-base material was processed and laid first and then a higher strength base material was processed and laid. The processing of the material was carried out at a central processing facility within the city of Edinburgh. The whole project saved an estimated 16,000 tonnes of CO2 and cost less than if traditional materials had been used.
