The study aims at investigating diffusion behaviors between virgin asphalt and recycled mastic (RAM) an atomistic scale. Firstly, a mutual model of asphalt–RAM considering the actual mass ratio filler to binder (F/A) condition was developed by molecular dynamic (MD)simulation. Secondly, indexes relative concentration (RC), radial distribution function (RDF) mean square displacement (MSD) were u...

The study and development of recycling techniques for pavements is an increasing activity in engineering nowadays. This research line demands a more realistic characterization of the material properties with the aim of simulate the asphalt mixture’s response placed into a multilayered system over granular bases, under dynamic loads, considering also temperature variation or strenght reduction f...

An optimal scheme of road paving maintenance was investigated by examining the environmental loading and cost considerations of pavement operations over a 30-year life cycle. Results indicated that the application of recycled materials in pavement construction and repair reduced the effects of environmental loading over the life cycle by approximately 40%. Furthermore, it was observed that envi...
