Zhang, H. (author), Anupam, K. (author), Scarpas, Athanasios (author), Kasbergen, C. (author), Erkens, S. (author)In the Netherlands, more than 80% of the highways are surfaced by porous asphalt (PA) mixes. The benefits of using PA mixes include, among others, the reduction of noise and the improvement of skid resistance. However, pavements with PA mixes are known to have a shorter lifetime and higher maintenance costs as compared with traditional dense...journal article 2020
