Lecture 4. Aggregates

important attribute of the aggregate s. Large aggregates are economically advantageous in Portland cement and asphalt concrete, as they have less surface areaand, therefore, require less binder. However, large aggregate mixes, whether asphalt orPortland cement concrete, are harsher and more difficult to work into place.
