Stone Matrix Asphalt (SMA) Friction Values

On some pavements in Utah, there has been some field friction (skid) tests on Stone Matrix Asphalt (SMA) surfaces that has caused some concern. This includes new pavements with low numbers and old pavements with high numbers and visa versa. This study will help in assessing whether or not there is a cause for concern because the SMA may be wearing too fast. Questions to be answered include: (1) Is SMA wearing too fast? (2) Is SMA being properly placed? (3) Are there recent placements that need to be fixed?

• Supplemental Notes:
  • Starting is pending completion of related UDOT study on laboratory polish values vs. field friction values.
