The quality control of aggregates lies within the scope of the management of the quality and durability of construction materials. Although it is evaluated as additional cost, it makes possible to optimize the resistance of construction materials. This paper aims at developing an easy classification procedure of qualification and control of the aggregates. This methodology is based on (1) the ...

The design of rock rubble revetments will be controlled by the size, shape and quality of rock available from nearby quarries. Flexible revetments often can tolerate a significant degree of displacement and shifting. Typically, the design conditions permit the movement of some 10% of the armour units and 2% damage during the design event.

On a quarry slope formed by three 15m faces at 70° with a minimum bench width of 15m, the reserves lost would amount to approximately 10,000 tonnes per 10m of face when compared with a 7m bench width (fig. 4). When this loss is scaled to actual quarry dimensions, very large quantities of reserves are lost.
