文摘
- •
Investigated homothetic behaviour of asphalt mixtures’ fracture properties.
- •
Determined fracture toughness of 216 dense graded asphalt specimens using SCB test.
- •
Evaluated the effect of specimen thickness using mixed-level factorial design.
- •
Recommended specimen thickness range to obviate geometric dependency on fracture.
