POROUS ASPHALT WEARING COURSES IN THE NETHERLANDS: STATE OF THE ART REVIEW

摘要: Since 1972, research has been carried out in the Netherlands to assess advantages of porous asphalt wearing courses relation conventional pavement structures. Efforts have also made quantify extra costs incurred by road managing authorities when using such materials. The chief users are expected be improved safety and reduced congestion. Furthermore, noise nuisance on roads is greatly diminished. On other hand, additional involved because shorter service life more expensive maintenance required for asphalt, as well fact that thicker constructions needed provide necessary bearing capacity. Based a cost-benefit analysis, it shown expenditure associated with can justified potential benefits. Dutch Department Public Works (Rijkswaterstaat) therefore decided install where possible national network, particularly motorways. characteristic properties related financial implications discussed this paper.
