Prompt: Layered Illustration of Sub-Base Construction: The graphic should depict a cross-sectional view of the ground where paving stones are to be laid. It should show distinct layers: the bottom layer of stabilized aggregates (cement or concrete), the compacting layer, and the top layer of paving stones. Labels and Descriptions: Each layer should be labeled: \"Stabilized Aggregate Base,\" \"Compacting Layer,\" and \"Paving Stones.\" A brief description next to each layer explaining its purpose, like \"Stabilized aggregates ensure stability and prevent shifting of paving stones\" and \"Compacting for even pressure distribution and longevity.\" Step-by-Step Process Icons: Small icons or figures showing the process of laying and compacting each layer. These could include a figure spreading the aggregate, another using a compactor on the base, and finally, the placement of paving stones. Visual Indicators of Depth and Density: The graphic should visually indicate the appropriate depth and density of each layer, perhaps with rulers or depth markers on the side of the sectional view.
