Abstract

The objective of this research is to assess the elastic deformations and permanent strains of reclaimed asphalt pavement (RAP) material as a base layer when it is treated or untreated with puzzolanic cement under cyclic loads. A large-scale cyclic plate loading testing (CPLT) device was developed for studying the mechanical characteristics of pavement base layer materials. When the RAP percentage of the mixtures increased, elastic deformations and permanent strains increased, but the opposite is true when the cement percentage increased. It was concluded that 100% RAP material can be used in base layers with 3% cement. The obtained deformation values and strain rates can be used as reasonable default design input values to be used by pavement designers when using RAP as a substitute for natural aggregate base layers.
