Abstract:	The paper explores the time-dependent compressibility of coarse crushed quartzitic slate, focusing on the effects of the previous loading history. Large diameter oedometer tests were performed at different relative humidity (or total suctions) and different overconsolidation ratios (OCR). Preliminary results suggested that pre-compressing the rockfill material at increasing OCRs lead to the progressive vanishing of rockfill delayed deformations.
