The standard proctor was called for in the project specifications. The majority of my experience with crushed limestone had been with CR-610 (95% passing the 1.5") and it has performed well, regardless of weather conditions. However, this was my first experience with this fine of a mixture and...
Thanks for the response Ron. At the time of placement the material was compacted and was stable. I was wondering if a thoroughly compacted and stable engineered fill would be so susceptible to rainfall. I've never seen a properly place material turn to such crap, due to rainfall alone. It's a...
