    The existing Superpave design system does not properly address performance prediction testing on mixture samples or decision-making during the design process. Performance of Coarse-Graded Mixes at Westrack - Premature Rutting. Published Date: The performance of flexible pavements relies heavily on the final quality of the hot.   Chattaraj (): Evaluation of wheel tracking and field rutting susceptibility of dense bituminous mixes, Road Materials and Pavement Design, DOI: /

    In addition, improved mechanistic structural properties were observed with the mixes employing –A (PG ) asphalt binder relative to the –A (PG ) asphalt binder, particularly the Saskatchewan Type 70 mix. The year rutting performance of the Radisson SPS-9A test site was evaluated and the field rutting results Author: Curtis BerthelotC. Berthelot, Diana PodborochynskiD. Podborochynski, Ania AnthonyA. Anthony, Brent M. This paper mainly investigated material design and performance of asphalt rubber stone mastic mix (AR-SMA). The rotation viscosity test was used to ascertain adoption of fiber in AR-SMA. Due to the swelling of asphalt rubber mortar, the gap-coarse graded aggregate must be used in asphalt rubber concrete to provide enough free space.

    Thus, it is important that pavement performance for coarse gradations be evaluated. Within this research work, performance evaluation took place with the use of the dynamic modulus test in indirect tension mode on coarse-graded mixtures consisting of field cores from 9 different pavements located in five districts of Minnesota. WesTrack was the Federal Highway Administration's (FHWA) test facility in Nevada for developing performance-related specifications for hot-mix asphalt pavement construction. It also provided some of the earliest data on the performance of Superpave asphal;See also PB;pg

Generally, coarse-graded mixes will require a higher dust-to-binder ratio than fine-graded mixes. For mixes below the restricted zone, the dust-to-binder ratio should be set at to However, the minimum VMA requirements must still be met to ensure adequate mixture durability.

The coarse mix shows higher dynamic moduli and better rutting performances than the fine mix, which were expected.

The fine mix failed (more than mm rutting passes) in HWTD rutting. The coarse mix shows better fatigue performance than the fine mix. Moreover, in report FHWA-RD, "Performance of Coarse-Graded Mixes at WesTrack-- Premature Rutting," the premature failure of several WesTrack pavement sections was partially attributed to " high binder contents due to high VMA values ".

June Simplified approach to determine the annual pavement temperature distribu-tion. Aggregates are the major component of asphalt mixtures, greatly influencing the mixtures resistance to failure.

The structure that is formed by the aggregates will depend mostly on the size distribution, shape and mineral composition. Coarse aggregate have a strong influence on the resistance to rutting, while fines provide stability to the by: Asphalt Pavement Analyzer Used to Assess Rutting Susceptibility of Hot-Mix Asphalt Designed for High Tire Pressure Aircraft Show all authors.

Rutting or permanent deformation (PD) is one of the most critical distresses occurring in hot-mix asphalt (HMA) pavements.

However, despite all of the recent efforts aimed at producing new test methods and better road materials, HMA rutting is still prevalent, particularly in hot regions and/or on highways with heavy truck-traffic by: 5. Analysis of parameters affecting asphalt mixture performance and new perspectives on the design parameters the field performance of the Westrack mixes showed that the asphalt mixtures containing 25% natural sand had better rutting and fatigue performance than the mixtures Performance of Coarse-Graded Mixes at Westrack–Premature Cited by: 2.

Performance of Coarse-Graded Mixes at Westrack - Premature Rutting. Published Date: It is also providing some of the earliest data on the performance of Superpave asphalt mixture designs under high rates of heavy truck loading. When Superpave-designed test sections placed at the track in June had very rapid rutting failures.

The aggregate gradation of the hot mix asphalts (HMA) used in southern Nevada before generally fell above the maximum density line (fine graded aggregate mix). Various asphaltic concrete pavem. As extracted from the DSS, three Texas commonly used HMA mixes (ranging from fine to coarse-graded) and five in-service highways were used for the study.

Overall, the laboratory HWTT yielded good correlations with field rutting performance data with a coefficient of determination generally exceeding 60% for most of the HMA rutting parameters Author: Lubinda F.

Even after enduring 20 HWTT load passes in a 50 °C heated water bath, Fig. 3 shows that all the HMA mixes exhibited sufficient rutting resistance in the laboratory, with all the RD values still lower than mm.

Interestingly, however, the fine-graded Type D mix (RD = mm) outperformed the coarse-graded Type C mixes at N d = 20 Author: Lubinda F.
