Development of a Permanent Deformation Model of Asphalt ...

Jan 01, 2009  This paper presents the permanent deformation model of asphalt mixtures in the KPDG. The permanent deformation model for various types of asphalt mixtures was developed by using the results of triaxial repeated loading tests. This model was calibrated with the accelerated pavement test (APT) and the Long-Term Pavement Performance (LTPP) database.
