Is there a way to test the field density of a gravel-filled layer?
Is there a way to test the field density of a gravel-filled layer?
(OP)
This is still related to my earlier thread about the Island road thing. Also, can the compaction % be measured accurately if the course is mostly 2-4inch aggregates with coral sand as its filler?
Thanks again.
Thanks again.

If there is a crusher available, that's one option. If not, I ask again...why do you need a subbase?

I level the site, dig a hole maybe 2 feet across and sufficiently deep to cover the whole layer thickness leaving sides undisturbed.
The line the hole with a strong, yet very flexible plastic something line two layers of the stuff you get from the dry cleaners.
Fill with water to the top.
Measure all your weights and get our answer.

This is one way of doing it with rock fill placement.

To determine the maximum density, you need to use something like that same container, but this time compact the material in lifts into the container using a plate tamper and determine the maximum weight after a few trials. You have to be careful to ensure that the voids at the top of the last lift are roughly the same by volume as the protrusions sticking out of the top of the container.
Also, I think it is vitally important to have me come over and conduct the test utilizing my vast array of experience with it...you did say it was a coral island in the Pacific right?

I appreciate any suggestions that you guys might have to further simplify the procedure, and I shall post the results of the field test to let you guys analyze the result
