How to Add Hydrated Lime to Asphalt An Overview

This section provides an overview of injecting hydrated lime into an asphalt drum mixer. In the early 1980s, the method of introducing hydrated lime into hot mix asphalt (HMA) in Georgia was to inject the hydrated lime in the drum mixer just “downstream” of the point at which the asphalt binder was injected.
