Characterization of bituminous-sealants utilizing modified bending beam rheometer

open access: yesTransportation Research Record: Journal of the Transportation Research Board, 2006
Early research showed that the current specification for the selection of crack sealants correlates poorly with field performance. To address this issue and help predict the low temperature properties of hot-poured bituminous sealants, a modified Bending Beam Rheometer (BBR) method is utilized. Eight sealants, with a wide range of rheological behaviors,
