Strategy for Pavement Surface Evaluation and Rating (PASER) = 6

CADT is Commercial Average Daily Traffic. RMA is Rubber Modified Asphalt.

For each CADT range in this case and a PASER for a good surface the cost estimate is $4–$7 per square yard and the performance is estimated to extend surface life 9 years (rubber modified micro-surfacing) or $4–$6 per square yard and the performance is estimated to extend surface life 7 years (hot rubber chip seal).
