The quality of materials for river embankment is reviewed from the point of view of soil mechanics, and the use is discussed of a soil classification system for the evaluation of fill materials. The results of field tests on embankments indicate that dry density and the degree of compaction of the river embankments are considerably lower than those of road embankments. Soil type of the fill materials and tamping equipment influence the degree of compaction. The report considers the present state of classification of materials for river embankments, as well as the evaluation of materials by the unified soil classification system. Investigations (mechanical analysis, consistency test, compaction test) on types of fill materials reveal that the range of the grading curve of the fill material which developed slope rupture due to rainfall may be determined. Values of density and moisture content are studied and the degree of compaction and void ratio are measured to study their relationship to the field moisture content, uniformity coefficient and cone index. The cone index (obtained by static penetration test) is useful in considering the trafficability of construction equipment. The variations of the degree of compaction due to the differences in the method of construction are reviewed, and road embankments are compared with river embankments. The degree of compaction, degree of saturation and air-void ratios to be used in quality control are discussed.
