The particle size distribution was defined following the limits established by the international regulations for pavement design (EN 933-2). A crushed or broken particle is defined in EN 933-5 as a particle whose surface is crushed or broken by more than 50%. The existence of flaky aggregates in bituminous mixes is undesirable and a

The experimental results demonstrated that filler particle size exerted a significant influence on the fatigue lives of bituminous mastics. When applied in terms of initial shear strain levels, the fatigue lives for both un-aged and aged mastics were ranked in descending order of filler particle size (F1, F2, and F3).
