At the end of the lifecycle of porous European mixes (PEM) many issues arise, such as RAP (reclaimed asphalt pavement) variability and potential for high percentage recycling. The objectives and scopes of this paper were focused into the analysis of the feasibility of a two-layer porous asphalt (TLPA) by recycling from-PEM RAP. RAP variability was examined and a method for facing its consequences was proposed. Results are encouraging about the possibility of achieving a satisfactory level of surface performance. Practical applications and perspectives in rehabilitation, maintenance, and research are outlined.

Abstract
At the end of the lifecycle of porous European mixes (PEM) many issues arise, such as RAP (reclaimed asphalt pavement) variability and potential for high percentage recycling. The objectives and scopes of this paper were focused into the analysis of the feasibility of a two-layer porous asphalt (TLPA) by recycling from-PEM RAP. RAP variability was examined and a method for facing its consequences was proposed. Results are encouraging about the possibility of achieving a satisfactory level of surface performance. Practical applications and perspectives in rehabilitation, maintenance, and research are outlined.File in questo prodotto:
