Book excerpt: Permeability is one of the most frequently used properties of a soil in the engineering practice but is also one of the most variable. Grain size distribution and density are known to significantly influence the permeability of sandy soils. Many sandy soils contain significant amounts of gravel of varying sizes. The effect of gravel content and size on permeability of sandy soils has not been closely examined. The objective of this research was to examine what effect, if any, varying proportions and sizes of gravel has on permeability values of different types of sand. Three different types of sandy soil, designated as Soil 1, Soil 2, and Soil 3, were tested for their grain size distributions and permeability values in the loose state. Based on grain size distributions, Soil 1 is a medium to fine-grained sand, Soil 2 contains the widest range of grain sizes and is the closest to being a well-graded sand, and Soil 3 is a coarse-grained sand. Additionally, three different gravel sizes, including 1′′- 3/4′′ (25.4 mm - 19.05 mm), 3/4′′- 1/2′′ (19.05 mm - 12.7 mm), and 1/2′′- #4 (12.7 mm - 4.75 mm), were chosen for the study. Each of the three gravel sizes was mixed with each of the three sands in increments of 5%, 10%, 15%, 20%, 25%, and 30%, by weight of sand, to prepare sand-gravel mixtures. The constant head permeability test was used to measure permeability of the three sands as well as their mixtures with gravel. The samples of sand and sand-gravel mixtures were poured into the permeameter in the loose state and allowed to saturate for 24 hours before measuring permeability. Three measurements of permeability were taken for each sand sample and each mixture and average values were obtained. Using Microsoft Excel, gravel content was plotted against permeability to examine the influence of a given size and proportion of gravel on each of the three types of sand used in the study. The results of this research shows that the presence of gravel influences the permeability of sandy soils, but the nature and degree of influence depends upon the type of the sand. For some sandy soils, the presence of gravel may facilitate water flow through the soil and increase their permeability whereas for others it may obstruct flow and decrease permeability. In some cases, the presence of gravel may not have any significant effect on permeability. It appears that the grain size distribution of the base sand, in relation to the gravel, plays a more important role in influencing the permeability of sand-gravel mixtures than the amount and size of gravel.
