Estimating volume of crushed stone using in-place volume from drawings
Estimating volume of crushed stone using in-place volume from drawings
(OP)
Seeking information on how I can estimate the volume of crushed stone to purchase if the only data available is the final volume (from bid drawings) of the material in-place after compaction,(i.e., what would the typical "fluff factors" be for #2 crushed stone, #3 washed crushed stone, subbase Type 4, etc.) Stone/Gravel suppliers have some estimates but I seek other data if available. Thank you.

My experience with clean crushed stone (from the midwest) is 1.15-1.2:1. Of course, I too first came across these numbers from the gravel pits owners. A good point mentioned by DRC is that the loose volume to compacted volume for clean crushed gravel is not as significant as that of class 5 or pit run sand which I usually runs up at about 1.35 or 1.4 :1. As also mentioned above, the pit guys know or should know their particular rock but if there values different significantly from the above numbers I would be somewhat suspect at least as far as my experience goes.

Do you still need info? I have been retired for some time, but have [somewhere] a list of different aggregate material and gradation, in tons/inch/sq.yd..
If you think that will help, I will look.
