Ravelling investigation of porous asphalt concrete based on fatigue characteristics of bitumen–stone adhesion and mortar
TL;DR: In this paper, the results of a testing program into the fatigue resistance and the adhesive zone were presented, and it was concluded that improvement of the adhesive zones will result in porous asphalt concrete with improved durability and lifetime.
The effect of aging on binder proporties of porous asphalt concrete
TL;DR: In this article, the effects of aging on the binder properties of porous asphalt concrete (PAC) are described, and a new mixture aging protocol in a weatherometer is proposed that combines the main environmental factors influencing field aging, i.e. temperature, UV light, and humidity/moisture.

2D and 3D meso-scale finite element models for ravelling analysis of porous asphalt concrete
TL;DR: In this article, 2D and 3D meso-level mechanical modeling for numerical analysis of ravelling resistance of porous asphalt concrete (PAC) is presented. But the main components (aggregate particle, mortar, interfacial zone and air void) in the actual mixture were represented in the meso scale model separately.

Investigation into material optimization and development for improved ravelling resistant porous asphalt concrete
TL;DR: In this article, Meso-mechanical simulations of porous asphalt concrete (PAC) under a moving tyre passage were performed to get insight into the in-mixture stresses, and the simulation results showed that ravelling developed over a wide range of temperatures and that particularly low or high temperatures were critical.

Microstructural finite-element analysis of influence of localized strain distribution on asphalt mix properties
Eyad Masad,Niranjanan Somadevan +1 more
TL;DR: In this article, a finite element model of the hot mix asphalt microstructure is developed to study the influence of localized strain distribution on the HMA mechanical response, and the results of testing asphalt binders in a dynamic shear rheometer and micro-structure analysis of idealized mastic are compared with experimental data obtained from the frequency sweep shear test.

Road safety effects of porous asphalt: a systematic review of evaluation studies
Rune Elvik,Poul Greibe +1 more
TL;DR: A systematic review of studies that have evaluated the effects of porous asphalt on nine different risk factors associated with accident occurrence found that four of the risk factors were favourably influenced by porous asphalt, three were adversely influenced, and two were not influenced by pores asphalt.
