Introduction Porous or permeable friction courses (PFC) are hot mix asphalt (HMA) mixtures placed at the surface of an asphalt pavement structure in a thin layer to produce several benefits for the traveling public in terms of safety, economy, and the environment. It is a sacrificial wearing course consisting of an aggregate with relatively uniform grading and little or no fines and mineral filler. [1]. Porous friction courses or Open-graded friction courses (OGFC) can also be explained as the mixes, which can be used to improve surface frictional resistance, provide additional storm water management measures, minimize hydroplaning, safety measures for drivers and pedestrians due to reduced splash and spray during rain, improve night visibility, lower pavement noise levels [2,3] and also reduced potential for black ice or ice due to improper drainage [4]. Apart from various benefits, the different terminologies which are used for PFC mixes throughout the world, includes open-graded asphalt (OGA), open-graded friction courses (OGFC), porous asphalt (PA), and porous friction course (PFC). In the United States permeable friction course (PFC) mixtures are termed new generation open-graded friction course (N-OGFC) mixtures, and similar European mixtures are identified as Porous Asphalt (PA) [5]. Basically, in dense-graded pavements, the surface course is designed to be impermeable so the water must move to the edge of the road by way of a small cross slope or camber, which is constructed in the pavement. However, in a porous asphalt pavement, the entire structure is designed to allow water to infiltrate the surface and then be stored in the base prior to exfiltration into the subgrade. Fig. 1 shows the movement of water within (a) a porous asphalt pavement, (b) an asphalt pavement with a porous friction course (PFC) or open-graded friction course (OGFC) overlay, and (c) a conventional dense-graded asphalt pavement [6]. Figure 1 Water movement through (a) porous asphalt pavement; (b) asphalt pavement with an PFC or OGFC overlay; (c) conventional asphalt pavement [6] Abstract: Porous Friction Course (PFC) mix are the type of open-graded bituminous mixtures used as wearing courses over the dense bituminous mix surfaces of pavement. These are mainly provided to serve as surface drainage layers to improve pavement surface permeability, skid-resistance, and visibility and also to mitigate hydroplaning effect during wet-weather conditions, in addition to reduction of vehicle tyre noise. In this present work mix designs were performed according to the Marshall Design procedure for a range of 4.5–5.5% binder content. This research has investigated the effect of aggregate gradation and binder content on the volumetric and performance related properties, including air-void, void in coarse aggregate for both dry rodded and mix condition, stone on stone contact, draindown, unaged abrasion loss, aged abrasion loss and permeability of PFC mix with neat bitumen (VG 30). The optimum mix obtained in this study is having a medium gradation with 5.0% binder content Keywords: Porous Friction Course; Open-Graded Bituminous Mixtures; Marshall Design; Aggregate Gradation; Optimum Mix.
