Crushed stone size limitation for non-expansive frostfree fill
Crushed stone size limitation for non-expansive frostfree fill
(OP)
Hi, Guys, Need help here.
I remember there was a thread before, which discusses about the crushed stone size for use as non-expansive frostfree fill. But I can not find this thread now. Can anybody direct me to that thread or tell me what is the max./min. crushed stone size for non-expansive frostfree fill?
Thank you very much.

No upper size limit, but 3" is a typical upper limit for practical compaction purposes.
For non-expansive, I expect the limit on fines achieves this purpose, but may need to exclude certain sources or mineral types if this is a possibility.

Yes I vaguely remember in a thread talking about 3" (or 5") maximum crushed stone diameter. So it is probably 3" is what I have seen.
