This book was released on 1994 with total page 274 pages. Available in PDF, EPUB and Kindle. Book excerpt: The final product of the Strategic Highway Research Program (SHRP) Asphalt Research Program is the SUPERPAVE (registered trademark) mix design system for new construction and overlays. This system employs a series of new performance-based specifications, test methods, and practices for material selection, accelerated performance testing, and mix design. This report documents these new specifications and procedures in a format suitable for eventual American Association of State Highway and Transportation Officials (AASHTO) standardization.

Available in PDF, EPUB and Kindle. Book excerpt: Classification of asphalt binder has evolved since the invention of asphalt pavement in 1870. Starting with penetration grading, moving forward to viscosity grading, and now the current system of performance grading (PG). All states in the US now adhere to some form of the PG system. During the last decade, several new modifiers and extenders have been introduced to modify the grade of a straight-run binder to achieve a target PG. In some cases, it has been observed that although a binder may meet the current PG specification, it may result in significantly sub-par performance. This suggests that the current PG specification does not accurately capture the performance characteristics of a binder. The main objective of this study was to use alternative chemical and mechanical tests on a large set of binders to identify differences in binders with a similar PG. This study examined the performance of 34 asphalt binders from 12 different binder sources using standard PG tests following AASHTO M320, as well as tests beyond the PG specification. The tests outside of the PG framework included chemical tests (X-ray fluorescence and spot), as well as other mechanical tests (Multiple Stress and Creep Recovery to measure permanent deformation potential at multiple high temperatures, BBR Pro to measure tensile strength at low temperatures, and poker chip test to measure tensile strength at intermediate temperature). For tests outside the PG specification, outlier criteria were developed based on the results found. Outliers were defined differently for each test and do not represent positive or negative outcomes in terms of expected performance. The tests outside of the PG specification (spot, [Delta] T [subscript c], aging sensitivity, poker chip, and low temperature strength) all produced many outliers, some even extreme outliers for binders with a similar PG. This study highlights the need for additional testing beyond the PG specification to improve binder grading. More performance testing on mixtures is needed to establish if outlier behavior is beneficial or detrimental.

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.

This book was released on 2013 with total page 75 pages. Available in PDF, EPUB and Kindle. Book excerpt: Due to particulates common in crumb rubber-modified asphalt binders, conventional PG grading using the Dynamic Shear Rheometer (DSR) with a gap height of 1.0 mm may not be valid and in accordance with current specifications. Asphalt binder testing and mixture testing was conducted on binders with and without crumb rubber modification to determine an asphalt binder test method which best matches the mixture performance. It was determined that the Multiple Stress Creep Recovery (MSCR) test, conducted with a gap height of 2.0 mm and at in-service temperatures, best correlated with Flow Number testing in the Asphalt Mixture Performance Tester (AMPT). This relationship was found to be better than that of the current DSR test procedure for high temperature PG grading.
