How It Works
1. Resonant Recycle PCC in Place
2. Excavate Fractured PCC, Place on Shoulder
3. Excavate Base Material, Level SubBase Course
4. Place Fractured PCC as Aggregate Base Material
5. Thoroughly Compact Aggregate Base Material
6. Lay new PCC/HMA in accordance with Plans
Resonant Recycle Concrete in Place
 7,000 yds per Shift
 Breaking to 5” Minus
Excavate Fractured PCC and Dig Base
Stockpiled Reusable Material
$$ The Savings $$
 Crushing Cost Typically Averages $2.50 - $3.00 per Ton
 Hauling Cost Averages $80/ per hour
o Average 3.5 trips per hour
o Average Hauling cost per ton $1.90
 Savings on 9” PCC = $2.20 square yard
 Estimated Construction Time Efficiency is 20-25%
