RECYCLING CONSTRUCTION MATERIALS

RECYCLING- BAUSTOFFE

This paper discusses recent considerable advances in the re-use of asphalt in road construction in Germany, although complete re-use is not yet possible. Sectors of road construction are indicated, where additional potentials can be realised. In maintaining existing roads, construction materials are increasingly being excavated from existing pavements; most of this material is asphalt, which constitutes about 95% of the carriageway surfacings of classified German roads. Methods for recovering and re-using asphalt in road construction have been developed and tested. It is estimated that between 10 and 15 million tonnes of asphalt are recycled per annum in West Germany, and more recovered asphalt is now available than is actually re-used; most benefits come from the re-use of materials in hot-coated materials production. There are also promising possibilities for cold preparation, especially for those recycling materials that cannot be added to hot preparations, for environmental reasons. Questions of environmental compatibility are especially important in assessing recycling construction materials. Practical solutions need to be provided for the assessment of environmental risks, with the aim of ensuring the recycling of construction materials.
