Compaction Characteristics of River Terrace Gravel
Publication: Journal of Geotechnical Engineering
Volume 111, Issue 8
Abstract
Large‐scale field and laboratory tests were carried out to investigate compaction characteristics of a river terrace gravel soil at the 120‐m high Sao Simao Dam in Brazil. The coarse fraction of the deposit was typically 3 in. (7.5 cm) maximum size, while the matrix (defined as material passing No. 4 sieve) was basically a clayey sand with and 35–50% passing the No. 200 sieve. The initial objective of the compaction tests was to develop the relationship between maximum density and percentage of gravel fraction which could be used for control of compaction in the field. The scope of the investigation was later enlarged to study the effects of energy of fraction, maximum particle size, mould dimensions, gradation of coarse material and water absorption on compaction of these soils. Field compaction trials were carried out to establish procedures for embankment construction and to evaluate the efficiency of two vibratory rollers.
