Fracture toughness evaluation of bituminous binders at low temperatures [PDF]

open access: yesMaterials and Structures, 2014
When asphalt roads turn brittle at low temperatures, they are no longer able to relax completely from traffic induced stresses and may also suffer damage through crack initiation and propagation. In order to avoid early structural damages, the bituminous binders must be selected very carefully.
