  • Introduction to Aggregates Transportation

    Introduction to Aggregates . Aggregates have many varied uses in transportation systems. The desirable properties and appropriate specifications are typically governed by the end use of the materials. In other words, aggregates that are well suited to a stabilized permeable base material may not be suitable for use in a PCC mixture.
