Regarding MOT1, crusher run, roadstone, whatever you call it, is the
balance of large bits and fines controlled?

For Type 1, it is (or should be) pretty tightly controlled, as there
is a specification (hence the name) which gives the percentage of
particles passing a sieve of a certain size..

Crusher run, and other things less so.

I have spread out what was left of an old bag, and there are lots of
large bits and not enough fines to consolidate. I suppose some of it
could have washed out over the 5 years it has been sitting there.

I supsect so,
