ABSTRACT
Asphalt pavements are part of a complex infrastructure which need to meet certain conditions in order to be able to be part of a stormwater management system. To do so, special asphalt mixtures with very high air-voids must be designed, in this article referred to as permeable asphalt (PeA) mixtures. While air-voids are crucial to achieve the desired permeability, this will have a negative impact on the durability of such mixtures. In this article, the main durability distress identified and studied is the ravelling or particle loss. Two tests were employed to study two extreme PeA mixtures, namely the scuffing test and the Cantabro test. The results show that the scuffing test is a good candidate to evaluate resistance to ravelling while the Cantabro test poses certain challenges when such mixtures are evaluated. Finally, the scuffing test was more sensitive to discriminate between the two mixtures while the Cantabro test give similar results.
