G1 GRAVEL

G1 GRAVEL

RE: G1 GRAVEL

The base material appears to be a well graded mix; it would be a matter of plotting it and comparing it to a Fuller or Weymouth curve. The sub-base is less intense. An aggregate mix does not have to meet anything other than what is spec'd; whether it works is another issue. Many jurisdictions have a standard Granular 'A' or 'A' Base and these often have a similar gradation. Maybe someone on the forum can advise if there is a 'legal' or 'standard' Granular 'A'. I've only seen the gradation spec'd and have never compared the specs for it.

Thanks Dik, but is there an official, technical standard showing aggregate/gravel gradation for G1 gravel?

RE: G1 GRAVEL

Try looking in the standard specifications of the department of transportation for the state or other jurisdiction where it would be used.

It could be like "Item 4" in parts of New York, a generic term for subbase gravel still in use, long after the relevant specification has been renamed. If that's the case, use the current spec. Since there is no spec for "Item 4," it could be pretty much anything that looks like subbase at first glance.

RE: G1 GRAVEL

Is it a local definition? It's just a matter of doing a sieve analysis to see that it conforms to the gradation... and a check of the constituent components for their conformance.

AC - I have the spec for Item 4 if you need it.đź‘Ť

RE: G1 GRAVEL

(OP)
AC, can I take a look at it? Does the spec reference technical standards like ASTM or AASHTO?

RE: G1 GRAVEL

OP - The spec I have for Item 4 is about 60 years old. I can post a copy when I get home.

RE: G1 GRAVEL

No problem AC. The book has helped me out a few times.

Could you give us the book title, author & publisher and the copyright date, plus any other information you wish to share about it.

Thank for the post.
