Porous asphalt (PA) is a distinct mixture type that deliberately designed with stone-on-stone
contact of the coarse aggregate fraction and high percentage of interconnected air voids to …

The highly polymer modified asphalt binders (HPMBs) are proposed and used for improving
raveling resistance of porous asphalt pavement. However, HPMBs undergo aging in service …

This research investigates the influence of aggregate gradation on the clogging
characteristics of porous asphalt mixtures. Ten representative gradations used for open …

After several years in service, porous asphalt looses permeability primarily due to clogging.
This paper presents a phenomenon, postulated as binder creep, as another source of …

The clogging of porous friction courses (PFCs) plays a major role in their resulting
performance. Clogging occurs due to deposition of external and internal materials, leading …

This paper summarises details of the laboratory investigation on the effect of various binders
on the performance and durability of porous friction course (PFC) mixes. Three different …

Open graded friction course (OGFC) is effective in improving the surface function of asphalt
pavements. However, it is prone to clogging including deformation-related and particle …

OGFC specimens with five air void contents and two clogging levels were scanned using X-
ray computed tomography (CT). The contents of total and connected voids before and after …

The compaction characteristics of porous asphalt (PA) mixtures are significantly different
from those of traditional dense-graded asphalt mixtures. Compaction efforts are critical for …

This paper presents the study on effect of aggregate gradation on the mix design and
performance properties of porous friction course (PFC) mixes. Six aggregate gradations …
