My neighbors and I just finished installing new driveways consisting of 3" uncompacted CDOT (Colorado DOT) #6 recycled concrete road base that I compacted with my tractor. This was followed by 3" uncompacted 1" x 3/4" recycled concrete rock. My neighbor compacted his with his pickup, and I rented a 5-ton vibratory smooth drum roller for aggregate/dirt compaction for mine.
All looked great for a while...a short while before the stuff started squirming and moving on us. Now it appears we've traded our old mud bog in winter driveways for another problem, namely bogging down in the rock.
The road base compacted wonderfully; but looked like crap. The rock top layer compacted nicely, looked like we wanted it to; but isn't staying compacted.
I have a few tons of left over road base I'm thinking of spreading out on my driveway in hopes of getting it into the spaces between the rock to help lock it together.
My neighbor's driveway is about 3,800 square feet, and mine is about 4,050 square feet.
Any thoughts on how to cure our problem?
