The ABC's of Preventative Maintenance
- A. The Right Pavement
- B. The Right Time
- C. The Right Treatment
There is nothing new about pavement preservation and preventive maintenance. People have been filling potholes and repairing cracks since the first asphalt pavement was laid back in the late 1800s. But have we been doing a good job? Probably not and that's because our maintenance programs have been reactive rather than proactive.
Smile: When the dentist fills a tooth, that's a corrective maintenance technique. When the dental hygienist cleans your teeth, that's a preventive maintenance technique. Regular visits to the dentist combined with a "conscientious program of oral hygiene" - that is a preventive maintenance program.
Preventive maintenance is a strategy - an organized, systematic approach that maintains or improves the condition of a pavement structure and slows future deterioration. Pavement Preservation changes your approach.
Preventative maintenance (PM) has the following 2 meanings:
1. The care and servicing by personnel for the purpose of maintaining equipment and facilities in satisfactory operating condition by providing for systematic inspection, detection, and correction of incipient failures either before they occur or before they develop into major defects.
2. Maintenance, including tests, measurements, adjustments, and procedures performed specifically to prevent faults from occurring.
