Recycling – There are three typical types of road construction techniques related to recycling the surface of distressed or damaged pavement. Rubblizing, Cold/Hot in-place Recycling, and Full-depth Reclamation. Rubblizing involves reducing the road to gravel and then applying a new surface, both hot and cold in-place recycling relies on …

Hot In-Place Recycling. Hot in-place recycling (HIR) is a less common form of hot asphalt recycling. There are three basic HIR construction processes in use, all of which involve a specialized plant in a continuous train operation (FHWA, 2001c [1] ): Heater scarification (Figure 1). This method uses a plant that heats the pavement surface ...
