Applying the Glover-Rowe Parameter to Evaluate Low-Temperature Performance of Hot Mix Asphalt LTPP Sections
Long-term pavement performance (LTPP) projects with hot mix asphalt were evaluated using three proposed indicators for low temperature cracking resistance. The primary objectives were to compare ways to combine stiffness and relaxation properties to correlate with cracking, assess data collection schemes in the LTPP relating to the analysis methods, and provide agencies with information to develop approaches for cataloging binders and performance. The Superpave low-temperature specification was compared with the recently developed Glover-Rowe parameter to relate laboratory-measured properties to field cracking. Complex modulus and phase-angle master curves were constructed to plot binder properties in Black Space. Results show the Superpave specification and Glover-Rowe parameter were able to capture one significantly cracked section which had test data obtained within a reasonable amount of time from field measurement. However, the available LTPP data was not ideal for Glover-Rowe analysis, where frequency sweeps at several temperatures are desired. The information presented is particularly relevant as tighter budgets delay maintenance and rehabilitation, exposing pavements to extensive aging.
