RE: Granular Fill/Gravel
Granular fill is usually manmade crushed rock so it is almost always angular and may include some sand and even some small amount of silt sized particles.
At least in my experience. Others may have a different view of this.

To a councillor, public or (sometimes) contractor, gravel is usually the surfacing aggregate placed on the completed grade (rural road x-section). To a road builder or engineer or inspector, gravel is screened, uncrushed aggregate (ie. raw gravels out of a stream bed or pit run out of a bank run through a grizzly). Granular has been processed to a specified specification.
