Precision of shear tests in evaluating asphalt mixtures Anderson, R Michael et al
Publication details: Transportation Research Record, 2003Description: nr 1832, s. 155-60Subject(s): Bibl.nr: VTI P8169:2003 Ref ; VTI P8167Location: Abstract: Various methods exist to measure the mechanical properties of hot-mix asphalt (HMA). To be useful such a test not only must measure a property that controls performance but also must be repeatable. The Strategic Highway Research Program developed tests with the Superpave shear tester that have been shown to be related to HMA performance. To date, repeatability has not been quantified. The results of a repeatability study for the measurement of shear stiffness (frequency sweep) and of permanent shear strain (repeated-load, constant-height testing) are reported.| Current library | Status | |
