I work for a GC. We were contracted to place 4" of aggregate base on compacted subgrade for a site access road, and then, after construction was complete come back, and place another 2" of aggregate base as a post-construction "cap." We initially agreed with the Owner to just place the 2" Cap with water and a roller for compaction. Well, now the Owner wants us to rip the bottom 4" of base and lay the 2" on top and re-wet/re-compact. Is there actually any value to this? Is there a chance that we don't acheive the same compaction that we had on the first 4" lift?
