Strategy for Pavement Surface Evaluation and Rating (PASER) = 4

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 fair surface the cost estimate is $70–$100 per ton and the performance is estimated to extend surface life 15 years.

CADT 0–500

Recommended Maintenance Method for RMA

  • Rubber modified surface (2” 5EL)

One layer at 2".

CADT 500–1,000

Recommended Maintenance Method for RMA

  • Rubber modified surface (more than 2” 5EL)

One layer at greater than 2".

CADT 1,000–3,400

Recommended Maintenance Method for RMA

  • Rubber modified surface (more than 2” 5EML)

One layer at greater than 2".

CADT >3,400

Recommended Maintenance Method for RMA

  • Rubber modified surface (more than 2” 5EMH)

One layer at greater than 2".
