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 Grade Determination of Crumb Rubber-modified Performance Graded Asphalt Binder by : Thomas Bennert
Download or read book Grade Determination of Crumb Rubber-modified Performance Graded Asphalt Binder written by Thomas Bennert and published by . 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.

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.

This book was released on 1994 with total page 124 pages. Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the two-stage validation of the proposed binder and mix specifications and tests. Stage 1 addresses the validation of the specifications and tests with laboratory data; Stage 2, with field performance data. The report is divided into four chapters, the first of which outlines the validation process. Chapters 2 and 3 are devoted to Stage 1 and 2 validation, respectively, and include a comprehensive discussion of the laboratory testing undertaken to evaluate asphalt concrete performance in terms of permanent deformation, fatigue cracking, and low-temperature cracking. Chapter 4 addresses the validation testing conducted using modified materials.
