Select Appropriate Stone Sizes: Use a range of stone sizes to ensure a well-graded mix. Smaller stones fill gaps between larger stones, enhancing compaction and strength. Maintain Proper Ratios: The ratio of crushed stone to cement is crucial. Typically, a 1:2:4 mix (one part cement, two parts sand, and four parts crushed stone) is recommended

As I remember my admittedly long-ago soils classes, the size will do little to influence the void ratio. Imagine simple spheres, like ball bearingMost details that I have seen call for 1" or 1.5" clear stone. I generally use 1.5" clear stone. The Minnesota Stormwater Manual has a lot of gooI suspect you mean 40% VOIDS, which is the maximum value that can generally be obtained by using clean, uniform, angular stone.

For filtration of the base material (the soil upon which the channel liner sits), you start withpsmart- I mean a void ratio of 0.4, what you have suggested is a void ratio of 0.67.Stone storage is commonly designed with a best-case value of 40% voids, hence my concern that the terms may have been swapped.
