The expected life span of the Preventative Maintenance Thin Lift Surface is approximately which of the following?

• A. 3 to 5 years
• B. 4 to 6 years
• C. 5 to 7 years
• D. 6 to 8 years

Answer: (D)

The main idea here is understanding how long a Preventative Maintenance Thin Lift Surface is expected to last. This thin wearing course is applied to seal and refresh the pavement surface, protect it from weathering, and restore ride quality, but it isn’t a structural fix. Because of its thin nature and its role as a surface treatment, its working life under normal conditions and standard SC traffic is typically about six to eight years.

So six to eight years is the best match because it reflects a balance between providing protective surface benefit and the realities of wear from traffic and climate. Shorter ranges like three to five years would imply a less durable treatment, while longer ranges aren’t consistent with the thin, preventive purpose of this surface.
