“…As one of main materials in pavement constructions, asphalt mixture is a heterogeneous composite composed of asphalt matrix, voids, and fine and coarse aggregates with complex shape, random orientation and distribution. The complex morphological features of aggregate vastly influence the mechanical properties, such as fracture performance [1][2][3]. The homogenized model often used for numerical simulations is too simple to predict realistic crack paths and load-carrying capacity, because a typical fracture pattern in asphalt mixture generally contains a main crack and some microcracks as well as some branches and tortuosities [4].…”

“…According to the American National Center for Asphalt Technology (NCAT), the minimum infiltration capacity of porous friction courses should be 100 m/day [10]. Moreover, it has been observed by some researchers that the minimum air void content that enables these infiltration capacities to be achieved is 15% [11].…”

Permeable pavements have been used widely across the world to manage urban stormwater. The hydrological behaviour of permeable surfaces is a complex process affected by many factors, such as rainfall intensity, rainfall duration, pavement geometrical conditions, and clogging level of the permeable surface, amongst others. This laboratory study was carried out to assess the influence of clogging level and rainfall intensity on the infiltration capacity of porous mixture surfaces used in Permeable Pavement Systems (PPS). Porous Concrete (PC) and Porous Asphalt (PA) mixtures with different air void contents (15%, 20%, and 25%) were subject to different clogging scenarios by using varying sediment loads (0, 500, and 1000 g/m 2 ). Permeability experiments were carried out for each clogging scenario through a new rainfall simulator specially developed, tailored, and calibrated for the laboratory simulation of a wide range of rainfall events. Permeability measurements were taken under all different scenarios as a result of the combination of the different rainfall events (50, 100, and 150 mm/h) simulated over the specimens of porous mixtures and the sediment loads applied to them. The results showed that the PC mixtures tested perform better than the PA ones in terms of infiltration capacity, showing less potential for clogging and being more easily cleaned by the wash-off produced by the simulated rainfall events.

“…While bitumen is a typical viscous material and its mechanical performances are very sensitive to the temperature. Numerous researches [14][15][16][17] proved that mechanical properties of the asphalt mixture are significantly affected by the microstructure and some material parameters including bitumen content, void content and gradation of aggregate particles. Several studies analyzed the inner structure of the aggregate and the asphalt mixture, however CT scanning is not commonly used for testing asphalt material.…”
