Book Synopsis Performance testing for Superpave and structural validation by : Nelson Gibson

Available in PDF, EPUB and Kindle. Book excerpt: The primary objective of this full-scale accelerated pavement testing was to evaluate the performance of unmodified and polymer modified asphalt binders and to recommend improved specification tests over existing SUperior PERforming Asphalt PAVEment (Superpave) binder performance grading methodologies. Candidate replacement tests were evaluated via their ability to discern fatigue cracking resistance and rutting. Two fatigue cracking specification tests were identified as more capable in capturing performance than others: binder yield energy and critical tip opening displacement. Two rutting specification tests that quantify irrecoverable deformations exhibited the best strength to capture rutting: multiple stress creep and recovery and oscillatory-based nonrecoverable stiffness. Based on the full-scale performance and laboratory tests, crumb rubber (recycled tires) modified asphalt (Arizona wet process) was shown to significantly slow or stop the growth of fatigue cracks in a composite asphalt pavement structure. A hybrid technique to modify asphalt with a combination of crumb rubber and conventional polymers (terminally blended) exhibited good fatigue cracking resistance relative to the control binder. Also, a simple addition of polyester fibers to asphalt mix was shown to have high resistance to fatigue cracking without the use of polymer modification. The research study also quantified the capabilities of the National Cooperative Highway Research Program's mechanistic-empirical pavement design and analysis methodologies to predict rutting and fatigue cracking of modified asphalts that were not captured in the calibration data from the Long-Term Pavement Performance program. Falling weight deflectometer, multidepth deflectometer, and strain gauge instrumentation were used to measure pavement response. The results illustrated that the nationally calibrated mechanistic-empirical performance models could differentiate between structural asphalt thickness but had difficulty differentiating modified from unmodified asphalt binder performance. Nonetheless, the mechanistic-empirical performance ranking and predictions were enhanced and improved using mixture-specific performance tests currently being implemented using the asphalt mixture performance tester.
Book Synopsis Superpave and the Aggregate Industry by : MS. Buchanan
Download or read book Superpave and the Aggregate Industry written by MS. Buchanan and published by . This book was released on 2006 with total page 16 pages. Available in PDF, EPUB and Kindle. Book excerpt: The Superior Performing Asphalt Pavement (Superpave) mix design system was developed under the Strategic Highway Research Program, which was completed in 1993. Superpave consists of new methodologies for evaluation and selection of hot mix asphalt (HMA) material constituents along with new laboratory compaction protocols. During Superpave development, significant research focused on the performance grade asphalt binder system and gyratory compaction development. In contrast, very little research was performed to determine those aggregate properties and specification requirements most closely related to HMA mix performance. In 2000, the aggregate industry prepared a white paper for, and at the request of, the Transportation Research Board Expert Task Group on Superpave Mixtures and Aggregates. The paper focused on discussion of aggregate related issues that presented challenges to the implementation and use of Superpave. Since the white paper was written, Superpave has undergone modifications (specifications and general use or practice) based on completed research and general knowledge obtained. Many Superpave modifications were addressed in varying degrees in the white paper, and it is now important to discuss the impact of these modifications on HMA performance and the aggregate industry. In addition, other aggregate related issues are presented and discussed, including inconsistent fine aggregate definition, influence of minus 0.075 mm sieve material on fine aggregate specific gravity determination, aggregate production and particle shape, and the influence of aggregate on dynamic modulus.

This book was released on 1997 with total page 21 pages. Available in PDF, EPUB and Kindle. Book excerpt: This paper discusses the evaluation of Superpave binder specification using pavements constructed with polymer-modified asphalt binders. Performance data collected from pavement test sections constructed in Sherman and Texarkana, Texas, were used in this evaluation. The Sherman pavement sections were overlays constructed in 1986 on US-75 whereas the Texarkana sections were all new construction on US 59/71 in late 1986 and early 1987. Dense-graded hot-mix asphalt (HMA), which contained 16-mm (5/8-inch) maximum size aggregate, was used. The aggregate comprised crushed limestone and field sand. Traffic loading and performance data were collected for both sites. Superpave binder tests were conducted on original asphalt binders saved from the construction projects. Superpave Performance Grade (PG grade) were then established for these binders. Predicted performance from the Superpave PG grades was compared against the field performance. Results indicate that the Superpave rutting parameter predicts rutting resistance reasonably accurately. It was found that the accuracy of prediction of thermal cracking is improved if failure properties are also considered. Finally, it was shown that the Superpave fatigue parameter needs reevaluation.
Book Synopsis Development of Superpave 5 Asphalt Mix Designs for Minnesota Pavements by : Tianhao Yan

Available in PDF, EPUB and Kindle. Book excerpt: High field density is desired for improving the durability of asphalt pavements. This research aims to develop Superpave 5 mixtures (more compactable than traditional Superpave mixtures) by using locally available materials to improve the field density in Minnesota. First, previous projects in Minnesota were investigated. The mean and standard deviation of field density in Minnesota were about 93.5 % Gmm and 1.5 % Gmm, respectively. Significant correlations were identified between field density and mix design indices, i.e., Ndesign, NMAS, and fine aggregate angularity (FAA). Four traditional Superpave mixtures were then selected and modified to Superpave 5 mixtures by adjusting their aggregate gradations while maintaining the asphalt binder content. Laboratory performance tests were performed to check the mechanical properties of the modified mixtures. The results showed it was feasible to design Superpave 5 mixtures (more compactable mixtures) by adjusting aggregate gradations, and the improved compactability of the mixtures did not adversely affect the performance of the mixtures for rutting, stiffness, and cracking resistance. Therefore, Superpave 5 mixtures can increase field density as well as other performances of asphalt pavements if implemented.
