For a civil engineer assessing construction aggregate, which factor is often more important than rock provenance?

Answer

Gradation (the distribution of particle sizes)

The civil engineer is often more concerned with gradation (the distribution of particle sizes) and strength for structural support, whereas the geologist prioritizes provenance and shape to reconstruct Earth’s history.
