Effects of Binder, Curing Time, Temperature, and Trafficking on Moduli of Stabilized and Unstabilized Full-Depth Reclamation Materials

This paper provides a summary of in situ layer moduli of several full- depth reclamation (FDR) materials used in an accelerated pavement test (APT) track. The reclaimed layers were constructed during the FDR of four lanes of 60 mm of rubberized hot-mix asphalt (HMA), 60 mm of HMA, and 130 mm of aggregate base. The FDR layer served as the base under a new HMA layer. Each lane had a different stabilization strategy, namely, unstabilized, stabilized with foam asphalt plus cement, stabilized with cement only, and stabilized with engineered asphalt emulsion. Falling weight deflectometer testing was conducted on the test track at various times during the course of the study, and the data were used to backcalculate the FDR layer moduli. The results were used to investigate the effects of each stabilization strategy, loading temperature, curing time, and trafficking on the in-place layer moduli of the FDR layers and to provide critical inputs for mechanistic–empirical pavement design of FDR layers.
