“…The deposition of 500 g/m 2 of sediments proved to be enough to reduce the infiltration capacity to the range of 63%-79% for PA mixtures and 57%-86% in PC mixtures on average, depending on the air void content. The infiltration capacity is normally higher in PC mixtures than in PA mixtures for the scenarios tested, probably due to the different gradations used for the two materials, which leads to different pore properties, and may result in different infiltration capacities and clogging dynamics for similar air void contents, according to previous studies [41][42][43].…”

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.

Permeable friction course (PFC) mixtures are a special type of hot mix asphalt (HMA) mixtures characterized by high total air voids (AV) content values to provide high permeability and noise reduction effectiveness, while high surface texture conditions can be ensured. Recent advancements in materials and HMA mixture evaluation led to increase the use of PFC mixtures over the last two decades as an alternative to improve highway safety and noise reduction. However, these developments on PFC mixtures generate the need for a comprehensive review to facilitate corresponding practical implementation. Consequently, the main objective of this paper is to provide a summary of research findings on PFC mixtures to improve the conception, design, and use of these HMA mixtures. In this context, the paper includes aspects related to advantages and limitations, volumetric properties, structural life, mixture distresses, and functionality of PFC mixtures. The aspects summarized provide a baseline for improvement of the current design and conception of PFC mixtures and offer guidelines for some future research developments.Keywords: Permeable friction course (PFC), mix design, hot mix asphalt (HMA), noise reductionpavements, drainable pavements. RESUMEN Las mezclas drenantes son un tipo especial de mezclas asfálticas caracterizadas por un alto contenido total de vacíos, que proporcionan alta permeabilidad y capacidad de reducción de los niveles de ruido, mientras se garantizan altos valores de textura superficial. Avances recientes en materiales y evaluación de mezclas asfálticas conllevaron al incremento del uso de mezclas drenantes en las dos últimas décadas

“…The very beneficial effects for the realistic simulation of the compaction on site in the laboratory environment by Superpave gyratory compactors is known and once more can be seen in the studies by various researchers that have been published in the last 13 years [54][55][56][57][58][59][60][61][62][63][64] . In all through these and the similar vast literature about the gyratory compaction studies published till date, limited studies about the 100 mm diameter specimens cored from 150 mm diameter gyratory compacted specimens for the preparation of laboratory prepared specimens have been discussed [19][20][21][22][23][24][25][26] . The vast majority of the other studies is about the physical and mechanical analyses of 150 mm diameter specimens prepared with Superpave gyratory compactors.…”

“…There are various important but "limited" number of studies in the literature that have been published up to date about the utilisation of 100 mm diameter specimens cored from 150 mm diameter gyratory compacted specimens for the preparation of laboratory specimens [19][20][21][22][23][24][25][26] . In all through these studies, the effect of compaction method, that is whether gyratory or Marshall compaction method have been utilised, and the resulting mechanical performance of mixes have been investigated.…”

Compaction technique used in Marshall design does not model the process of actual rolling procedures on site exactly. Carrying out laboratory compaction of dense bituminous mixtures with Superpave gyratory compactors is a more realistic way of simulating actual compaction. In this study, mechanical differences of reference and polypropylene modified asphalt mixtures were compared using Superpave gyratory and Marshall compaction methods by carrying out repeated creep tests utilising universal testing machine. In addition, there is no standard Superpave design procedure for 100 mm diameter samples till date. The other purpose of this study is to propose new standards for the compaction and testing procedures of these 100 mm specimens. Indeed, extensive studies have shown that the design gyration number should be 40 for reference and 33 for polypropylene modified specimens under medium traffic conditions for the similar and specific type of aggregate sources, bitumen, aggregate gradation, mix proportioning, modification technique and laboratory conditions. Moreover, it was shown that, the asphalt samples produced by Superpave gyratory compactor were much resistant to destructive rutting effects than the asphalt specimens prepared by Marshall design.
