Properties of porous friction course mixes for flexible pavements - Vol.42(3), Mar - New Delhi Indian Road Congress 2014 - 19-30p.
Porous friction courses (PFC) are open-graded bituminous mixtures used as surfacing or wearing courses over sound dense bituminous mix surfaces of highway and runway pavements. These are provided to serve as surface drainage layers to improve the pavement skid-resistance and to mitigate hydroplaning effect during wet-weather conditions, in addition to attenuation of vehicle tyre noise. A number of research findings on characterization of PFC mixes reported the use of Superpave Gyratory Compactor (SGC). Major differences were observed in the design gyrations (N sub design) and the design aggregate gradations. This paper summarizes the laboratory investigation on the effect of aggregate gradation on the mix design (with regard to volumetric properties, permeability, unaged abrasion loss, and drain..
