Which treatment is expected to last 7-10 years?

The overlay treatment is expected to last 7-10 years due to its design and application process. An overlay involves placing a new layer of asphalt over existing pavement, which extends the life of the road by providing a fresh surface that can better withstand traffic loads and environmental factors. This technique can restore skid resistance and improve the overall ride quality of the pavement.

The durability of an overlay is often associated with good maintenance practices and the condition of the underlying pavement. When properly installed and maintained, overlays can effectively address minor surface defects and extend the lifespan of the roadway significantly within that expected timeframe.
