This paper deals with the subject of influence of the porous asphalt mixture parameters on the ravelling performance. Porous asphalt is a type of hot asphalt mixture that is used as a wearing course. The ideal application of porous asphalt is in places with less traffic load and in parking areas where water "stagnation" occurs. Porous asphalt can also be used on highways where it has the role of solving aquaplaning problems. More recently, by improving the quality of materials and improving the specifications of porous asphalt, porous asphalt has shown many advantages over conventional asphalt mixtures. It has proven to be extremely good at reducing traffic noise, solving water splashes, increasing traffic safety, as well as being characterized by high water permeability, reducing heat islands in urban areas, and being environmentally friendly. The main disadvantages of porous asphalt are durability, cost and disintegration, or ravelling. Due to the discontinuous granulometric composition of the porous asphalt, it is allowed to drain. Because of its discontinuous grading structure, filtering is enabled. Since this type of mixture has an open structure, the problem of durability occurs (because of the ravelling performance). Ravelling represents the loss of aggregate grains that occurs due to the weakening of the bond between aggregate grain and bitumen. Ravelling areas can be hazardous and affect traffic safety. The goal of this paper is to analyze and determine the influence of design parameters of porous asphalt project mixture on the resistance to the ravelling performance, according to HRN EN 12697-17.
