The shape and surface texture of aggregate particles is important for both Portland cement concrete (PCC) and hot mix asphalt (HMA).
For preparing PCC, would you prefer round and smooth aggregate or rough and angular aggregate?

In PCC, where aggregates are used as an inexpensive high-strength material to occupy volume, workability is the major issue regarding particle shape. Therefore, in PCC, rounded particles are better as they provide this important feature by virtue of their coarse surfaces and larger surface areas
