What is Pavement Preservation?
Pavement preservation is a cost-effective technique that extends pavement lifespans. This form of proactive repair makes highway road conditions safer, allows for a free flow of traffic and saves taxpayer dollars.
Traditional highway repair follows a “worst-first” strategy, where roads are repaired only when conditions are unserviceable. This is not only dangerous to roads with declining conditions, but it is not a sound financial strategy.
When a road is only repaired when no longer drivable, it requires a complete reconstruction. This is much more costly than the new preventative measures that have been introduced.
Road repair can be divided into two categories:
Routine maintenance is the common traditional practice, where sections of the road are repaired only after events or seasons. This restores serviceability of the road.
Preventative maintenance is a proactive measure to extend road lifespans while also repairing road damage. This not only restores serviceability but also reduces aging of the pavement.
Preventative maintenance is the new alternative to traditional pavement repair and promises many benefits. Each dollar spent on preventative measures now will save an estimated six dollars in future routine maintenance.
