Abstract:Original Report Date: December 1999. The main objective of the most recent MLS test program was to conduct a comparative study of two rehabilitation processes, Remixer and Dustrol, constructed on the southbound and northbound lanes of US 281 near Jacksboro, Texas, in the Fort Worth District, in 1995 and 1996, respectively. The underlying pavements are composite asphalt layers, with the first construction undertaken in 1957.
Since no temperature control was provided during trafficking, the tests were conducted in consecutive, similar seasons to reduce variability induced by temperature changes. Performance was evaluated in terms of surface rutting, loss of stiffness in pavement layers, and permanent deformation in the layers. Tools used during the study included an on-site weather station, nondestructive testing equipment (GPR, FWD, SPA, PSPA, SASW, DCP), in-situ instrumentation (MDD), and the Hamburg wheel-tracking device. The findings provided conclusive results on the relative performance of the two rehab strategies. The results indicated that the Remixer process performs better than the Dustrol process on resisting rutting, although both mixes are stable, with no sign of premature failure. Based on the good performance of the Remixer rehab on its sound underlying structure, it was used on a section of US 175 in the Dallas District. However, it was found later that the Remixer could not stop reflected cracking on the US 175 project.
