RECYCLING: RECYCLED ASPHALT FOR ROAD CONSTRUCTION

Since 1977, when asphalt recycling at static hot-mix plants was introduced on a commercial basis in Denmark, the techniques and products made from it have gradually obtained acceptance among asphalt contractors and road authorities. Today, approximately 80 per cent of all asphalt materials removed from roads (300,000 tonnes per year), are systematically being upgraded and recycled by the asphalt industry, making Denmark one of the leading nations in this area of resource conservation. 75 per cent of all static asphalt mixing plants in Denmark are now equipped with facilities for recycling, and reclaimed asphalt is being incorporated into all essential types of asphalt hot-mixes for use in road construction and pavement maintenance. In 1988, approximately 37 per cent of the total volume of asphalt hot-mixes produced in Denmark (four million tonnes) was characterised by a content of reclaimed asphalt. This article briefly describes the recycling process (Modified Minnesota Method), the use of recycled asphalt in the maintenance of Copenhagen airport (1983), and its use in two motorway construction projects in 1989. The 28 kilometre dual lane motorway in Jutland was constructed with 15-20 per cent reclaimed asphalt in the base course mix, while the 21 kilometre dual lane motorway in Zealand used 45 per cent reclaimed asphalt in the base course.
