    Abstract

    This paper focuses on the influence of suction dissipation upon the development of compressive settling in compacted rock aggregates due to immersion. The influence of disintegration of the material upon the development of compressive settling is also addressed. For this, a staged compression-immersion test is carried out on compacted quartz porphyry as well as mudstone aggregates. The results show that for the quartz porphyry aggregates, the influence of suction is slight. For the mudstone aggregates, a relatively high suction exists initially, probably due to the inherent nature of this type of rock, and the influence of the dissipation of mere suction upon compressive settling could be smaller than that of disintegration or degradation of the aggregates.
