Rubblization
What is Resonant Rubblization?
Why Rubblization?
What does Rubblization do?
Rubblization is the process of fracturing portland cement concrete (PCC) pavement into angular 
pieces for direct overlay. This process turns the old, existing PCC into the new aggregate base.
Approximately 65% less expensive and five times faster than total reconstruction, rubblization 
creates a perpetual pavement with a 22+ year design life according to multiple independent 
studies (TRB, NAPA, Asphalt Institute, etc.). Requires no major reconstruction with minimal 
surface rehabilitation.
Rubblization has been proven to eliminate reflective cracking, ASR/ACR degeneration, joint 
deterioration, etc. Studies show to completely eliminate reflective cracking, max particle 
dimensions must be 1-9”.

Coarse Aggregate Recycling
In-Place PCC Recycling is the method of using larger maximum particle size with a proper 
gradation, as base/subbase layers in road reconstruction projects all in the confines of the 
existing road. Existing PCC is pulverized in-place, excavated into MCR-300 for screening and 
crushing to proper gradation, stockpiled on the shoulder, then placed and compacted as new 
aggregate base material.
The MCR-300 coupled with the Resonant 
Frequency Breaker will eliminate excessive 
hauling and crushing costs needed to produce 
proper gradation, while maintaining 
compaction requirements for the new stable 
base layer. Construction time, cost savings and 
eliminated truckloads are some of many 
benefits with In-Place PCC Recycling

Break for Removal
Resonant Machines specializes in speed and smaller particle sizes when projects require PCC 
pavement removal. Contractors experience 30% less truckloads, lower crushing costs, steel 
debonding and faster load time with RMI, which creates overall cost savings for the project. 
RMI’s precision breaking is the most cost effective, efficient solution to expediting your con-
struction project.
