<br /> Unacceptable Subrounded Stones have nearly plane sides but have well-rounded corners and edges
<br /> Rounded Stones have smoothly curved sides and no edges
<br /> NOTE:See®GO of Table 5 for additional angular stone requirements.

<br /> PLEASE NOTE:
<br /> 1. The listed AASHTO designations are for gradations only. The stone must also be clean, crushed, angular. For example, a
<br /> specification for#4 stone would state: "clean, crushed, angular no. 4(AASHTO M43)stone."
<br /> 2.As an alternate to Proctor Testing and field density measurements on open graded stone, Storm Tech compaction requirements are met
