Compaction for waterlines
Compaction for waterlines
(OP)
Do people have a standard preference for using either standard proctor or modified proctor for checking compaction along waterlines? I've been doing some inspections where the spec's in the waterline detail call out for compacting to 95% modified proctor yet the state DOT and town highway dept. all have there own spec's which use standard proctor.
The project is replacing an 80-yr old waterline with a new ductile iron line and re-using the existing backfill in the trench, except for new gravel base for the road.

It was amazing to see the size of the boulders in the old trench that the guys 80 years ago had to remove and then they just rolled them right back on top of the waterline. Those, however, are now finding a useful life elsewhere.
