Rock aggregate products are essential for our infrastructure and society as a whole. Rock aggregates are mainly used for road and railroad construction and for the manufacture of asphalt and concrete. High-quality, low-cost, environmentally friendly rock aggregates and recycling of materials are important resources for the development of a sustainable society. The relative amount of crushed bedrock is steadily increasing, as a result of the joint effort by the authorities and industry to save natural gravel. It is important to support this trend by all possible means. One of the primary problems is the fact that the available resources of natural aggregates are diminishing in most of Europe. To protect the natural environment, the use of natural sand and gravel aggregates must be reduced and crushed aggregates, instead, will have to be used in concrete production in the future. The paper focuses on this problem and presents proposals for how to deal with it by co-operative research.

Engineering Geology for Tomorrow’s Cities
This book and the accompanying CD-ROM provide a statement of our knowledge and understanding of engineering geology as applied to the urban environment at the start of the 21st century. In particular, this volume demonstrates that:
working standards originally developed nationally are becoming internationalized;
risk assessment, rather than just assessment of hazards, is driving decision-making;
geo-environmental change, whether climatically or anthropogenically driven, is becoming better understood;
greater use of underground space is being made;
the relentless advance of information technology is providing new opportunities for engineering geologists to interpret and visualize the subsurface.
This book shows that in developed and developing countries alike, engineering geolgists are increasingly exchanging ideas and learning from each other in a genuine two-way process. These ideas will contribute significantly to the sustainable development of both new and long-established urban environments world-wide.
