FIELD ANALYSIS OF RUTTING IN OVERLAYS OF

The data were analyzed to develop regression relations between rutting and mixture properties of the asphalt concrete overlays. The analysis clearly shows the importance of material properties to the development of rutting, particularly the gradation parameters. Eleven of the projects were cored for structural testing in the laboratory.

Field Observations of Rutting and Their Practical

The pattern that emerges from the observation of a series of full-scale experiments is this: After the initial period, the deformation and rutting can be related in cumulative traffic by power index values between 0.2 and 0.5, at least up to the point at which surface crack­ ing is evident.
