Are compaction tests of #610 crushed stone reliable?

You asked, "Are compaction tests of #610 crushed stone reliable?" The answer is yes. If a proctor, either D698 or D1557, can be performed on the material then in-place density tests can be performed on it. My recollection of the gradation for #610 stone is Percent Passing 1 ½" = 100 1"= 85-100 ½" = 40-75 No. 4 = 15-40

3.2 Determination of the bulk relative density and apparent relative density (It is not possible to determine the bulk relative density of cohesive soils because it is not possible to obtain the saturated surface-dry condition.) 3.2.1 After soaking the sample, drain off the free water and spread the sample on a flat

Compacting AASHTO #57

As the stone is placed, we use a trackhoe bucket to beat on the stone and press it into the sidewalls - helps to reduce the potential for future stone loss into footing sidewalls, and subsequent loss of contact between poured footings and in-place stone. As far as testing w/ a nuclear gauge, it is impossible.

Bulk Density and Void Percentage Test for Aggregates
