Abstract
Recent large-scale earth constructions such as Second Tomei and Meishin Expressways have needed rational compaction method with compaction vibrator roller of a large size. Therefore, in-site rolling compaction tests on two sites and a series of laboratory tests were carried out to develop a reasonable procedure that thick finishing layers can be sufficiently compacted by a big vibrator roller. Tests results showed that settlement performance of embankments with compacted to the layer of 60cm thick by the 300kN vibrator roller satisfies the prescribed quality standard. Furthermore, influence of density gradients on defomation characteristics of soil layer has been quantitatively evaluated.
