| Popis: | This paper presents a comparative parallel about resistance to disintegration or cohesion loss from the results of the Cantabro test in dry and wet methods for specimens made with two types of porous asphalt friction courses exposed: the first of them designed and produced from the modified asphalt cement penetration standard 60-70 x10 -1 mm with an additive consisting of fatty acid amides in a proportion of 2.0% with respect to the total mass of the binder present in said mixture and the second without modifying additive. The porous asphalt friction courses are a type of surface in a pavement structure which by its characteristic particle size distribution, allow rapid infiltration of stormwater runoff. Thus, it can be achieved to final disposal of the tread. The experimental model that led to the mechanical characterization based on resistance to the disintegration of this type of mixture in particular, was made based on the methodology of the Cantabro test in Angeles machine, revealing satisfactory results for a type of porous asphalt friction courses. |
