USE OF RUBBLIZING EXPANDS

This article describes the process of rubblizing, or reducing portland cement concrete (pcc) slabs into aggregate bases for new hot-mix asphalt (HMA) pavements by using a resonant pavement breaker. Rubblizing has recently been used successfully by the states of Maryland, Mississippi and West Virginia. Rubblizing is usually accomplished by a pavement breaker machine manufactured by the Resonant Technology Company. The machine rubblizes the pcc pavement by high frequency vibration of the pavement breaker shoe, which delivers a 2000 foot-pound blow at the rate of 44 cycles per second. Details of the rubblizing process and the three states' programs mentioned above are included.
