Description

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.  

Aggregates play a primary role in the ability of asphalt concrete to carry traffic loads. The interaction between the aggregate particles is responsible, in large part, for the strength and deformation characteristics of the asphalt.

This course will relate the physical properties of aggregates to the performance of asphalt mixtures. It will also cover the most important coarse and fine aggregate properties for asphalt mixtures and the tests used to determine those properties. Lastly, the role of aggregates in providing skid resistance on asphalt concrete pavements will be explained. 

Who Should Take This Course 

This course is intended for a variety of positions within local agencies and tribal governments, with an emphasis on those involved in the construction, maintenance, and testing process for highways and structures.
