RECYCLING -- THE KEY TO FUTURE ROAD MAINTENANCE THROUGH RECLAMATION AND REPROCESSING OF THE WORLD'S EXISTING PAVEMENTS

The overall economics and reasons for consideration of reclamation and reprocessing of existing pavements are discussed. The paper explores the potential economic value attributed to the above in the light of current and future values and supplies of natural resources -- specifically natural aggregates and petroleum products. Discussed are three main categories: Profiling for surface restoration and increased safety factors on existing pavements; reclamation of materials from existing pavements; and the recycling of reclaimed material for usage on existing pavements for the upgrading of these pavements as well as usage for the reconstruction of badly deteriorated pavements. The paper also discusses the various techniques available as well as the current state of the art, and considers the future in this segment of the road construction and maintenance industry.
