SENIOR-ARRIETA, V  and  CORDOBA-MAQUILON, J.E. Mechanical characterization of porous asphalt mixes modified with fatty acid amides -FAA-. Ing. Investig. [online]. 2017, vol.37, n.1, pp.43-48. ISSN 0120-5609.

ABSTRACT Porous asphalt mixes (PAM), conform a special road surface for asphalt pavement structures. They have a distinctive particle size distribution that permits infiltration of the runoff storm water due to its voids content which is about 20 %. Many researchers have conducted studies and concluded that the use of modified asphalts is completely necessary to design PAM. Organic and chemical additives and special procedures such as foamed asphalt and including fibers into the mixture design have enhanced the performance of PAM, during its service life. This paper is based on the mechanical characterization of PAM and how the asphalt binder modified with fatty acid amides, influenced on their behavior and performance. In order to do so, an experimental methodology based on laboratory tests aimed to establish a comparison between porous asphalt mixes, designed and produced with a 60-70 in 1/10 mm penetration at 25 °C neat asphalt binder, and another using modified asphalt with fatty acid amides.

Keywords : Modified asphalt; porous asphalt mixes; hot asphalt mixes; hydroplaning; fatty acid amides; Cantabro test.
