- W2242028306 abstract "At the conclusion of the Strategic Highway Research Program (SHRP), the asphalt industry was introduced to the Superpave mix design and analysis system. This mix design system was developed by the SHRP researchers to include volumetric mix design, mechanical property tests, and performance prediction analyses for evaluating asphalt mixtures, particularly for pavements exposed to high traffic or high stress. The Superpave mechanical property test procedures conducted using the Superpave Shear Tester (SST) were adopted by the American Association of State Highway and Transportation Officials (AASHTO) as a provisional standard (AASHTO TP7). As part of the implementation of the SHRP products, the Federal Highway Administration was charged with evaluating the of the AASHTO TP7 method. A ruggedness experiment evaluates a proposed test procedure so that potential sources of variability can be identified and corrected before precision and bias testing is conducted. This research discusses ruggedness testing that was conducted on the shear frequency sweep test at constant height described in AASHTO TP7. Although the SST tests were never fully implemented as envisioned by SHRP, there still are enough research agencies using shear tests to measure mechanical properties of asphalt mixtures to warrant an investigation into the variability inherent in the test procedures. The ruggedness evaluation of the shear frequency sweep test indicated that test temperature had a significant effect on the shear modulus (stiffness) at 10 Hz loading frequency (G*10Hz). However, the temperature tolerance specified in AASHTO TP7 (+/- 0.5 deg C) appeared reasonable, resulting in an expected difference of approximately 10% in G*10Hz. The percentage of air voids in the specimen also affected the value of G*10Hz, but not significantly according to the ruggedness evaluation. A tolerance of +/- 0.5% in the specimen air voids should likewise be expected to change the G*10Hz value by no more than 10%. All other main factors were considered non-significant. Although the National Cooperative Highway Research Program (NCHRP) project 9-19 research has indicated that axial tests are recommended for mechanical property testing of asphalt mixtures, the concept of ruggedness testing and effects of main factors should remain somewhat unchanged. In other words, the sensitivity of shear frequency sweep results to test temperature, percentage of air voids, or applied strain should be similar to the sensitivity of dynamic modulus results." @default.
