This set of photos presents rubblization and asphalt overlay of controlled-access highways. Note the capability of the MHB Badger Breaker® to rubblize one lane while maintaining traffic in the adjacent lane. Multiple MHBs are utilized on high production projects.
Rubblize to Rehabilitate – West Virginia
Through the monitoring of pavement conditions in West Virginia, the DOH has documented that the warranty pavements, using rubblization, are out-performing traditional full depth new construction pavements.
Mechanistic Design Data from ODOT Instrumented Pavement Sites – Phase 1 Report
This investigation examined data obtained from three previously-instrumented pavement test sites in Oregon. Data processing algorithms and templates were developed for each test site that facilitated full processing of all the data to build databases representing each site. Investigation of site data found that most of the collected data could be successfully processed and observed trends in the data were as expected (e.g., seasonal changes affected pavement response). The location that compared rubblized base to aggregate base clearly demonstrated the effect of the rubblized base through a 50% reduction in strain at the bottom of the asphalt layer.
