Description:

A study of the rutting performance from plastic flow on 33 hot mix asphalt (HMA) pavements was performed. Air voids in the wheel path of3.0% clearly distinguished pavements with good and bad rutting performances: air voids less than 3% rutted and air voids greater than 3% did not rut from plastic flow. Samples were recompacted in the Texas gyratory using the high and low efforts. Samples recompacted with air voids greater than 2.0% with the high effort or 3.0% with the low effort indicated good performance with respect to rutting. The air voids after the low effort of compaction correlated best with the air voids in the wheel path for high volume roadways. Component properties (aggregates, asphalt cements, gradation, etc.) did not reveal why the good pavements performed well and the bad pavements did poorly. Performance was directly tied to the void properties. Field verification should be performed throughout the project to provide indications of the future rutting performance of the pavements.
