ABSTRACT
ABSTRACT: In an effort to more effectively fund pavement rehabilitation, the Virginia Department of Transportation (VDOT) is investigating the use of full-depth reclamation (FDR) as a pavement rehabilitation alternative on a trial basis. This paper documents the in-situ structural testing related to foamed asphalt and asphalt emulsion-based FDR process on an existing two-lane rural highway in Virginia. The effectiveness of the FDR process was characterized by performing falling-weight deflectometer (FWD) testing to compare the before-and-after structural condition. The results of the study show an increase in structural capacity of FDR sections over the first seven months of service. The FWD results allowed for the calculation of a structural layer coefficient for the FDR pavement sections containing different binding agents. Data used in this study suggests initial differences in structural capacity of FDR sections based on binding agent used. Additional laboratory testing and field monitoring of the projects is recommended.
