Rehabilitation Strategies for Highway Pavements

Full-depth asphalt concrete pavements are those in which all layers contain an asphaltic binder. The asphalt concrete layers (which may be of different gradations and asphalt cement contents) are constructed directly on the prepared subgrade. Portland cement concrete pavement is also sometimes referred to as concrete pavement or rigid pavement.

PAVEMENT TECHNOLOGY ADVISORY - RUBBLIZING - PTA-M1

Rubblizing is a rehabilitation process in which an existing deteriorated concrete pavement is broken into small pieces (maximum size 9 inches) while still in place. The “rubblized” concrete pavement, in effect, becomes an aggregate base for a hot-mix asphalt (HMA) or concrete overlay. Figure 1: Rubblized Concrete with Overlay
