If they haven't tamped it thoroughly,
(knocking all the tiny air pockets out of),
the cement/fine sand/water slurry that coated the gravel,
will be prone to waterlogging in steady rain.
The next night of frost should see some freeze/thaw cracking.That's before we consider the negligible bond strength between
cementitious and bituminous systems.Expect the feathered edges to go with the refuse hgv.
^Is that sand/gravel/cement,
or,
resin-based?
