Which of the following is listed as a benefit of the Preventative Maintenance Thin Lift Surface?

Preventative Maintenance Thin Lift Surface is designed to restore ride quality by applying a very thin asphalt overlay that smooths out the surface. That smoothing acts to reduce roughness and create a more even riding surface, which is why improving smoothness is the primary benefit. It’s not intended to fix major structural defects or potholes, which require deeper repairs, so “correct surface defects” isn’t the main goal. Likewise, drainage and tire noise aren’t the primary purposes of this thin lift; any changes to skid resistance or drainage would be secondary and limited. So the standout benefit you’d expect from this treatment is a smoother, more comfortable ride.
