Is there terminology confusion? Design Life Service Life Life Extension Routine Maintenance Preventive Maintenance Minor Rehabilitation Design Life Service Life Life Extension Routine Maintenance Preventive Maintenance Minor Rehabilitation
8
Preventive Maintenance is a component of Pavement Preservation
