Figure 1
The illustration presents three distinct sections arranged in a two-column layout. The left column contains two photos, labeled “a” and “b.” Photo “a,” positioned at the top left, is a close-up photograph of a pile of irregularly shaped, dark, coarse granular material. Directly below it, photo “b” displays a pile of much finer, dark granular material, looking more like sand or fine powder. The right column features a line graph labeled “c,” positioned horizontally adjacent to the two photos. This graph plots “Cumulative Passing (percent)” on the vertical axis, ranging from 0 to 100 in increments of 20, against “Sieve size (millimeters)” on the horizontal axis, which is on a logarithmic scale ranging from 0.01 to 100. The graph contains four distinct lines, each representing a different material, identified by a legend in the top-left corner of the graph. The red line with upward-pointing triangles represents “Sand,” the blue line with diamonds represents “R 8,” the magenta line with circles represents “C R,” and the green line with squares represents “C A.” All the curves exhibit an upward trend, with the order of the curves from left to right being Sand, R 8, C R, and C A.Eco-aggregates (a) crumb rubber (CR), (b) RESIN8 (R8), and (c) particle size distribution curve showing CR, R8, sand and coarse aggregate (CA).
