Aggregates: Geology, Prospection, Environment, Testing Extraction, Specifications, Processing Plants Equipment, Quality

This work sets out to explore the "aggregates" field in a comprehensive manner, from natural deposits to finished products. Topics covered include: the aggregates market in France; tests and specifications; loading and transport; the quarrying of massive rocks; and crushing and grinding.

Louis Primel holds a Ph.D. in applied geology. He has devoted a major part of his career to studies and research on aggregates, anti was associated with such research projects which were being carried out by the network of Bridges and Highways Laboratories in collaboration with producers of aggregates and manufacturers of equipment. He has also been a teacher at the Ecole Nationale des Pants et Chaussees (ENPC) (National School of Bridges and Highways) and Secretary-General of the International Association for Engineering Geology and the Environment.

Claude Tourenq, a Ph.D. in applied geology, has carried out research on the physical and mechanical properties of rocks at the Central Laboratory of Bridges and Highways in Paris, and during the same period he taught geology applied to civil engineering at the Ecole Nation ale des Ponts et Chaussees. He then specialized in the field of aggregates.
