We have a long gravel on clay driveway that is about 2 years old. It has
done fairly well until recently when we had a lot of rain & snow. The
gravel just got pushed down in the the gel/slime/whatever and the driveway
got in bad shape in a hurry. This residential driveway has more traffic
than a normal residential driveway but it is limited to about 10-15 cars a
day and normal a normal residential delivery truck (USPS, UPS, FEDEX) 2 or
so times a week.

I would appreciate any help with how to improve the driveway

I have had driveways of gravel atop clay for 34 years, in a place
where winters last 4 to 5 months. The only known "improvement"
is to add gravel every 4 to 6 years and roll judiciously. (It is no good
just accelerating the natural tendency for the gravel to burrow down
into the clay.)
