Aggregate Characteristics Affecting Friction Numbers on Bituminous Pavements in Alabama. Summary
The AHD makes pavement friction measurements on all roads in the state approximately every two years. These measurements are an indication of the ability of the pavement to resist skidding. More than 10,000 miles of asphalt pavement are tested during each cycle. The friction results vary considerably. Some pavements maintain high resistance over a period of many years, while friction diminishes rapidly on others. A research project was needed to help determine why friction varied from location to location. In particular, the roles of key variables (aggregate size, type, and mix; traffic volume; age; etc.) were not well defined. The abundance of friction data provided a good tool with which to assess the contributions of these variables.
