NAPA Publishes Rubblization


The National Asphalt Pavement Association announces the publication of a new technical document, Rubblization: Design and Construction Guidelines on Rubblizing and Overlaying PCC Pavements with Hot-Mix Asphalt. Rubblization is a rehabilitation process that turns a Portland cement concrete (PCC) pavement that has reached the end of its service life into an excellent base for a new, smooth, durable, safe, quiet asphalt pavement.

NAPA's new 32-page publication provides comprehensive guidance on every aspect of rubblization technology, from evaluation of the existing PCC pavement, through design of the hot-mix asphalt (HMA) overlay, to final construction of the HMWA. The various types of rubblization equipment are covered. Other issues addressed include preparation of the PCC pavement, drainage, dealing with utilities and underground structures, quality control, and troubleshooting.
