GRAVEL is a material is caused by fragmentation of the various rocks of the crust, naturally, as causes of rivers, dry wells, sedimentation or banks either by removing artificial crushing rocks.
The reuse of gravel produced by debris on the roads can be and streets, creating a resistance and impermiabilización, generating greater durability.
Some of the properties of the aggregate is that it gives the thickness and consistency of the concrete, so the quality is very important to have a good result

generally encouraged the use of local materials, and due to its weight, transferring involves high energy consumption . The largest benefit lies in its longevity, one of the most sustainable materials.
gravitates The most noticeable impact in the extraction stage, caused by variation in the field, the change of landscape and ecosystem. For general use, this type of material is causing major problems.
CERTIFICATION
The new Framework Evaluation of product certification systems was launched in June 2009. Products and materials that are certified by GBCA (Green Building Council Australia) which was created in 2002 is a recognized certification system which will have greater access to "deemed to satisfy" the status of compliance within the Green Star
Environmental Impact Assessment (EIA)
Proponents must activity predict changes that occur in the middle, and suggest corrective measures prevent or mitigate as far as possible the inherent disorders that are caused, including a plan that will restore the physical and biological environment to its original state.
