We are just starting to get into public underground utility work. I'm doing a project where the new 12" SDR35 storm sewer will cross an existing road. I want to make 100% sure there are no future settlement issues to deal with. What kind of crushed aggregate is best to use? How will I know not to overcompact the stone with the Ho-Pac? How close to the pipe can I start compacting without damaging the pipe? How much water should we spray on the aggregate before we compact?
