In this image, different rock types are given different colors. In the flexible pavement design, the three layers (i.e.AC, BC and SBC) are calculated as an output. For example, the flow of water over a certain area may deposit a certain composition of silt for a thousand years, and then a change in the flow of water, its source, weather conditions, etc, may alter the composition of the silt being deposited, creating a different layer. The layers of rock are different thicknesses because of the way the sediments are formed and squashed together. Earlier our Earth had only rocks. This new set of conditions may persist for a shorter period of time, giving rise to a thinner layer on top of the first one, or a longer period of time, giving rise to a thicker one.
