ABSTRACT
Respect for the environment should lead to maximum use of excavation materials.

Rock excavations will normally be suitable for causeways. Always they are constructed test sections to define systems placing and methods of control.

In certain cases the rock will be suitable for the production of graded aggregate or aggregate quality. the use of mobile crawler crushing and screening is recommended. The latter allow to classify the product in three or four sizes. To balance production needs can use local quarries or ride a simple tertiary crushing equipment.

The existence of these devices work allow recycling some demolition products for use as concourse or granular base.
