Assessment of eco-friendly modified asphalt mixture using PMA methodology

The research program aims to define a new methodological procedure to design eco-friendly modified asphalt using PMA methodology in substitution to PMB technology. In the starting phase two different mixes were optimized using SUPERPAVE methodology, and the ITS value was evaluated. The first mixture is a Traditional Mixture (TM) and another one is an Modified Mixture (MM) with the addition of 5% (by total mass of bitumen) of polymeric compound using PMA technology. From the ITS analysis, the modified mixture shows an ITS value higher about of 20% than traditional Hot Mix Asphalt.
