Testing and interpreting permeability of asphalt mixes

Csaba Tóth, Soós Zoltán, Zsuzsanna IGAZVÖLGYI

Abstract

This paper presents a field study showing the distribution of air voids in asphalt layers, and the potential effect of water on pavement performance. The paper also discusses the applicability of the European test method and equipment for assessing permeability of asphalt layers. A series of laboratory permeability tests were conducted on in-situ core samples and laboratory samples. It was found that mixes with smaller particle sizes, the air void content results in lower permeability compared to mixes with larger particle sizes.

Keywords
asphalt permeability, pavement moisture content, air voids content, Computed Tomography (CT)
