Current needs in state department of transportation (DOT) pavement design and management programs require explicit information about the development of rutting in asphalt concrete mixtures. Many state DOTs are considering implementing the 1986 AASHTO Pavement Design Guide, and they require guidance in analyzing mix performance as a part of pavement design. Rutting data are examined from the AASHO Road Test sections built over cement-treated bases. The recorded rut depths are analyzed to derive relationships for the asphalt mixture used during the AASHO Road Test. Load equivalency factors are derived from the rutting data clearly showing that the AASHTO rigid pavement load equivalency factors more closely indicate the development of rutting under different axle weights and configurations. The fundamental properties describing rutting potential provide data useful in comparing rutting behavior of current mixes with that developed in the AASHO Road Test.
