In place recycling of granular bases of asphalt pavements

This work presents the results of a study intended the obtaining and introduction of the auxiliary elements to assure the road pavements technological control of rehabilitation which involves the recycling in place of granular bases. This verification was made using two techniques, the CBR in place verification, through the use of DCP (Dynamic Cone Penetrometer), and the granulometric framing, through the curve of Talbot, for recycled materials. The investigations were accomplished starting from practical applications in roads which involved, in an experimental way, the pavements rehabilitation through the base course recycling, incorporating the surface layer. Through the data processing obtained in the tests, it was possible the elaboration of the technical specification proposal of the granular bases recycling.
