Figure 7.
The graph illustrates the particle size distribution of a blend, comparing washed and unwashed materials. The X axis represents sieve sizes measured in millimetres, ranging from zero point zero one to ten. The Y axis shows the percentage of passing particles, ranging from zero to one hundred percent. Three distinct lines are plotted, a solid black line for unwashed samples, a solid green line for washed samples, and dotted blue and red lines indicating upper and lower specification limits, respectively, cited from Vicroads, 2017 a. Data points for each line are represented by shapes, triangles for unwashed, squares for washed, and x marks for specification limits. The graph exhibits a consistent increase in percentage passing as the sieve size increases, with the unwashed samples consistently higher than the washed.Particle size distribution of unbound RCA and RG blend
