Method of renewing a road surface of bituminous mix, with cold application of the recycled covering material

摘要

A method for renewing a road surface based on bituminous mix and granular mix, comprising removing the road surface to be replaced, by scarifying; collecting the removed material and conveying it to devices for screening and crushing to predetermined particle size, and then to a mixer where aqueous bitumen emulsion is added, the mixture obtained being recycled directly to form the new road surface by depositing and levelling the mixture after spraying bitumen emulsion, and finally rolling the road surface thus formed. A self-propelled machine for implementing said operations is also provided.
