Micromechanical Modelling of Porous Asphalt Mixtures

With the attempt to reduce traffic noise, porous asphalt (PA) mixture is widely used as a wearing course on the highways in the Netherlands. However, due to the open structure, PA mix pavement easily suffers from the loss of individual aggregates from its surface, which is named as ravelling. After the initial ravelling, the damage can rapidly develop into potholes which can significantly reduce the driving safety of the pavement....
