The process of laying the base materials begins with the placement of larger, clean stones. These stones form the foundation layer, which stabilizes the subsequent layers of material. Over this foundation, spread an even layer of crushed stone or pea gravel. This layer should then be thoroughly compacted to enhance the stability of the …

For Subgrade and base course preparation, choose crushed stone aggregate within specified gradations. Ensure the largest stone particle size is between 1/2 to 2/3 of the proposed compacted base course thickness (typically 4 inches). Spread the crushed stone directly from trucks using spreading boxes or from roadside stone aggregate stacks.
