Thick-Layer Construction Using Sandy Soil as Material and Embankment Performance Evaluation: Assessment of Rolling Compaction Test Results
This paper describes how there has been significant advances in material handling (transport) equipment in recent years because leveling machine performance as earth-moving equipment are made in very large sizes. Along with these advances, construction work to thicken embankment layers is also taking place in an increasing number of cases. This thick-layer construction is work that uses large vibrating rollers to thicken each layer within the embankment. This paper describes experimental work to thicken embankments using mountain sand and examines the results obtained from that work. Embankment thickening is compared in two cases; one using conventional thick-layer construction (t = 60 cm) and the other using mountain sand (t =120 cm) in order to check limits on roll compacting effects. Results revealed that the same degree of compaction can be obtained to t = 90 cm with mountain sand. Moreover, compression tests and shear tests were made at the dry bulk density for this depth, to confirm the long-term compressibility and shearing characteristics. In these tests, the authors confirmed that the same performance was obtained as in conventional embankment work.
