Download or read book Evaluation of Superpave Binder Specification with Performance of Polymer-Modified Asphalt Pavements written by R. Dongré and published by . 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 excerpt: This paper discusses the SUPERPAVE System of products which resulted from the Stretegic Highway Research Program (SHRP). These products addressed the following pavement distresses for dense graded asphalt mixtures: permanent deformation, fatigue cracking, low temperature cracking, including the effects of aging and moisture damage of these distresses. Although other types of pavement distress in hot mix asphalt pavement were recognized by the SHRP planners, a decision was made not to include them in this research effort. The final products of the program are: 1. A performance-based specification for asphalt binders complete with supporting tests; A performance-based specification for asphalt-aggregate mixtures complete with supporting tests and performance prediction modls; 3. A mixture design and analysis system which incorporates both the asphalt binder specification and the asphalt mixture specification; 4. A protocol to evaluate modified asphalt binder and 5. a SUPERPAVE software support system. For the covering abstract of this conference, see IRRD number 863140.

This book was released on 2016-10-31 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: The Superpave specifications and equipment, introduced in 1993, represented a major advancement with respect to offering a better understanding of the behavior and characteristics of asphalt binders based on their rheological properties. However, the Superpave high-temperature test protocol has been shown to be inadequate for characterizing the high-temperature behavior (rutting resistance) of asphalt binders, particularly polymer modified ones. Recently, a specification based on the Multiple Stress Creep Recovery (MSCR) test has been proposed to address the shortcomings of the Superpave high-temperature binder specifications. This study aims to investigate the merits of implementing the MSCR test and specification as a replacement for the conventional high-temperature testing in the Performance Graded (PG) system. A statistical analysis was conducted on a dataset from Indiana Department of Transportation (INDOT) to see how MSCR and PG procedures differ in grading different binders used in the state. In addition, an experimental study was conducted using seventeen different modified and unmodified binders. In addition to binder tests, seven of the binders were selected to conduct asphalt mixture tests such as dynamic modulus and flow number. The results confirm that the MSCR test is a suitable replacement for the current PG high temperature test since it provides a better tool to rank modified asphalt binders as well as unmodified ones. That is, creep compliance from the MSCR test more fundamentally represents binder behavior at high temperatures compared to the PG rutting parameter. In addition, the very simplified approach, known as grade-bumping, used in the current PG system to account for high traffic levels and low speed limits can be eliminated when using the MSCR test. The MSCR test also provides a better coefficient of correlation (at both stress levels) with flow number test results than the PG rutting parameter, again indicating that it more accurately reflects binder performance at high temperatures.

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.
