EPOXY MODIFIED OPEN-GRADED POROUS ASPHALT 10 The superior oxidation resistance of the epoxy material was clearly evident in Cantabro tests conducted at both 25°C and 10°C. As surface ravelling is the principle failure mode for OGPA these results suggest a markedly improved field life for epoxy bitumen OGPA compared to the standard asphalt.

New experimental polymer-modified bitumen with a high-vinyl content polymer was fabricated for porous asphalt (PA) mixtures. The bitumen with maximum stability was achieved using storage stability, gelation criteria and physical bitumen tests. A dynamic shear rheometer was used to compare the complex modulus, number of fatigue cycles, yield ...

Porous Asphalt is a pervious pavement designed to allow stormwater infiltration through the surface into the soil below. The water is naturally absorbed and filtered, and the pollutants are removed. In contrast, regular asphalt pavement is an impervious surface that sheds and repels rainfall and surface pollutants.

In this study, porous asphalt cores were obtained from field test sections each year from 2014 to 2017. The evolution of the properties of the field cores and the recovered bitumen with time was investigated. Cyclic indirect tensile tests were performed to determine changes in the mechanical behavior of porous asphalt due to aging.

porous asphalt layers consist of asphalt binder, aggregates, sands, and recycled materials and are much like a dense-graded hot mix asphalt mixture. By limiting the amount of fines, the porous mixture allows for more air voids. (Typically between 16% and 22% is recommended.)

Porous asphalt concrete is an open, bitumen-bonded material and it has been applied primarily to mitigate pavement traffic noise (Hamzah et al., 2013a). The binding is generated at the stone–stone contact regions where a limited amount of mortar acts as binding agent (Mo, 2010). Porous asphalt is characterized by high amount of air voids and ...
