PORTLAND CEMENT CONCRETE PAVEMENT PULVERIZING EQUIPMENT

Portland cement concrete (PCC) is most commonly broken with gravity-drop hammers, trailer-mounted diesel hammers, spring-arm hammers, and vibrating-beam breakers. PCC pavement breaking, steel removal, hauling, crushing, and sizing can be performed for a price in terms of pavement of about $3.50/sq yd to $4.50/sq yd or $7.00/ton to $9.00/ton of aggregate produced. Pavement breaking and steel removal prices are in the range of $0.50/sq yd to $1.50/sq yd. Steel removal remains a labor-intensive, low-production operation. Breaking and crushing operations need to be improved in order that large quantities of coarse aggregate can be produced from PCC. Field operations need improvement to prevent or reduce the amount of base course contamination. About 3,200,000 sq yd of PCC was recycled in the 1985 construction season. Considering the condition of pavements in the United States, current recycling quantities, and expected growth of recycling, 50 to 100 equipment units will be required within 20 years to break or pulverize PCC pavements.
