• Abstract:
  Sprinkle Treatment is the application of a properly graded, pre-coated, non-polishing aggregate to a hot asphaltic concrete wearing course immediately behind the paving machine. The "sprinkled" chips are embedded into the mat with the initial rolling operation. By embedding expensive imported, non-polishing aggregates only in the wearing course surface rather than using it in the entire mix, desirable friction properties can be achieved and a substantial conservation of materials and costs can be realized. Depending on the rate of application of chips, it is possible to obtain a surface macrotexture which can also improve hydroplaning characteristics. This study is initiated to document the construction of a Sprinkle Treatment field trial on a high speed/high volume roadway and present the performance data obtained for three years after construction.
