What size and type of aggregate should I use as fill material for Gravelpave2?

The best choice for aggregate is small (3/16’), angular, hard stones that have been thoroughly washed. The angular stones will lock together in the ring creating a smooth, stable surface. The range of options is vast, and designers have used everything from recycled glass to crushed seashells. Softer materials that break down, such as limestone or decomposed granite, should be avoided as they will cause the surface to lose porosity. If opting for a round gravel, rings should not be overfilled as it will cause a slip-hazard.
