EFFECT OF ASPHALT CONCRETE PARAMETERS ON RUTTING PERFORMANCE: A FIELD INVESTIGATION (WITH DISCUSSION)

In Saskatchewan the development of wheel track ruts in asphalt concrete pavements has been regarded as isolated occurrences usually associated with a localized problem such as overasphalting or structural underdesign. A widespread rutting problem has not been perceived, but several examples of significant rutting have become apparent on highway segments scattered throughout the Province. Rutting is generally considered to consist of two components, namely plastic deformation in the asphalt bound materials and general subsidence of the subgrade and the overlying pavement layers. The type of rutting investigated and reported in this paper is plastic deformation of the asphalt layers. As such, the study focuses primarily on the mix design parameters of these materials. Structural design of the pavement was not addressed. Details of the study and its findings are contained in this report. Various sites were chosen including both poor and good performing sections. The objective of the experimental program was to quantify the mix which had been designed, the mix which was placed and the mix which exists today to determine why it did or did not perform as desired.
