CADT is Commercial Average Daily Traffic. RMA is Rubber Modified Asphalt. EL, EML, and EMH refer to mix design. The mixture number (2–5) corresponds to gradation, where 2 is the base mix and 5 is the top mix.
For each CADT range in this case and a PASER for a poor surface the cost estimate is $70–$100 per ton and the performance is estimated to extend surface life 15 years.
