Textbook Problem

In a certain beach restoration project involving mixing and compaction of various sandy soils, the engineers studied the role of median grain size, D50, on compacted density. Binary granular mixes of coarse and fine materials were synthetically prepared by mixing different volume percentages of finer soils with coarser soils at three different median grain size ratios; D50-coarse/D50-fine = 1.67, 3, and 6.

The table below shows all mixes used in this study. For each binary mix, the maximum dry unit weight was determined by compacting the mix in the Proctor mold using the same compactive energy. Perform the following tasks.

a. On the same graph, plot the variation of dry unit weight with the volume percent of finer soil for each median grain size ratio.

b. What can you conclude about the role of D50-coarse/D50-fine ratios on compacted density of granular binary mixes?

(a)

To determine

Plot the variation of dry unit weight with the volume percent of finer soil for each median grain size ratio.

Explanation

Given information:

The three different median grain size ratios (D50coarseD50fine) are 1.67,3, and 6

(b)

To determine

Provide the role of D50coarseD50fine ratios on compacted density of granular binary mixes.
