Subbase vs. Base (AASHTO Design Guide)
Our crushed stone base course material in Laos and in India all measured at more than 100. Our subbase, being crushed rock was higher too. I thought (from memory) that crushed stone subbase was 0.11 and crushed stone base was 0.14. I'd say, if you have CBR 30 for base course, get a different base material or turn it into a cement …
Determining the Physical Properties of Aggregate Products and …
The aggregate impact value = 10.14%. Discussions: the aggregate impact value gives a relative measure of the resistance of an aggregate to sudden impact, which in some aggregates differs from its resistance to slowly applied compressive load. Aggregate with aggregate impact value higher than 30% may be abnormal.

Development of a 3/4-Inch Minus Crushed Base Course Specification
Current Montana specifications exist for a 2-inch minus (Grade 5A) and 1½-inch minus (Grade 6A) crushed aggregate course (MDT, 2014 – §701.02.4); however, because gravel sources in Montana are becoming limited, investigating the use of a gravel specification for maximum particle sizes less than ¾ inch is desirable.
