Abstract:Full depth reclamation (FDR) is one of the three major types of asphalt recycling techniques. FDR is considered when the pavement is highly deteriorated or has deep cracking due to design deficiencies or an inadequate base. Other indications that a road could use FDR are frequent transverse and lateral cracking, reflective cracking, severe rutting and frost heaves. The objective of this task is to develop a mix design procedure for FDR. Due to the large variations among the various types of FDR stabilizers, a separate mix design method was developed for each type of FDR. Detailed summary of the processes that were used in the mix design for each FDR type are included.
