“…It was discovered that the macrotextures single grain size aggregates have been expanded as grain size has increased, macrotextures of mixed grain size aggregates have been expanded as the proportion of small grain size particles has declined and both fine aggregates and mineral powders have improved aggregate shape. In the meanwhile, the impact of the aggregate scale on the macro-structure of the pavement was greater than that of the proportion of voids in coarse aggregate (VCA) in the dry rodded condition [26].…”

Nowadays porous asphalt pavement increase usage other than the traditional type of asphalt pavement. In that sense porous asphalt specially use in the parking areas and walk ways for pedestrian. There are diverse ways that has been done in order to stick up to permanent degradation such as adding fibers and modifiers like polymers, chemical modifiers, expandars, oxidants and antioxidents, hydrocarbons and antistripping to enhance the fatigue and service life of the pavement. To use these type of additives in porous asphalt pavement some additive increase the mechanical performance of porous asphalt mixture and improve the serviceability of the pavement. Digital image processing use these type of pavement to reduce the air void of the asphalt mixture and increase the physical properties of the porous asphalt pavement. This review paper mainly discuss the overall performance and advantage of porous asphalt using different types of additives.

“…The macrotexture, on the other hand, corresponds with surface irregularities that range between 0.1 mm and 20 mm vertically and between 0.5 mm and 50 mm horizontally [14]. It is mainly controlled by the granulometric curve of the aggregates used in the asphalt mixes and the degrees of compaction during the pavement construction [16,17]. Macrotexture contributes to the hysteretic friction at the macroscale level and also provides drainage paths for water to escape from the tire/road contact patch in wet conditions [18,19].…”
