Effects of specimen size and loading conditions on the ...

2021-2-1  Thus, in the available standards for asphalt concrete, for each specimen diameter, the minimum thickness is set with a strict requirement for aggregate size, to avoid localized effects and variation in test results. Aggregate size also affects the crack propagation pattern in the SCB test sample due to non-homogeneity.
