Download or read book Fiber Dosage Effects in Asphalt Binders and Hot Mix Asphalt Mixtures written by Ashraf Alrajhi and published by . This book was released on 2012 with total page 184 pages. Available in PDF, EPUB and Kindle. Book excerpt: The application of fibers and other materials in asphalt mixes has been studied and applied over the past five decades in order to improve pavement performance around the world. This thesis highlights the characteristics and performance properties of modified asphalt mixes using a blend of polypropylene and aramid fibers, The main objective of this study was to evaluate the effect of adding different fiber dosages on the laboratory performance of both asphalt binder and mixture. The laboratory study was conducted on sixteen different dosages and blends of the fibers, with various combinations of polypropylene and aramid, using binder tests as well as hot mix asphalt tests. The binder tests included: penetration, softing point, and Brookfield viscosity tests. The asphalt mixture tests included the dynamic modulus, and indirect tensile strength. The binder test results indicated that the best viscosity - temperature susceptibility performance would be from the blend of three dosages of polypropylene and one dosage of aramid, the dynamic modulus test results also confirmed this finding. Overall, in almost every case, the addition of fibers resulted in an increase in mixture stiffness regardless of fiber content. From the indirect tensile strength results, the polypropylene fibers had less of an effect on post peak failure than the aramid fibers. Overall, the aramid fibers yielded better results than the polypropylene fibers. This study has important implications for the future of pavement design and the prospect of using optimal dosages of polypropylene and aramid fibers in further research to further determine their long-term performance and characteristics used in real world applications.

Available in PDF, EPUB and Kindle. Book excerpt: The urgent need for infrastructure rehabilitation and maintenance has led to a rise in the levels of research into bituminous materials. Breakthroughs in sustainable and environmentally friendly bituminous materials are certain to have a significant impact on national economies and energy sustainability. This book will provide a comprehensive review on recent advances in research and technological developments in bituminous materials. Opening with an introductory chapter on asphalt materials and a section on the perspective of bituminous binder specifications, Part One covers the physiochemical characterisation and analysis of asphalt materials. Part Two reviews the range of distress (damage) mechanisms in asphalt materials, with chapters covering cracking, deformation, fatigue cracking and healing of asphalt mixtures, as well as moisture damage and the multiscale oxidative aging modelling approach for asphalt concrete. The final section of this book investigates alternative asphalt materials. Chapters within this section review such aspects as alternative binders for asphalt pavements such as bio binders and RAP, paving with asphalt emulsions and aggregate grading optimization. Provides an insight into advances and techniques for bituminous materials Comprehensively reviews the physicochemical characteristics of bituminous materials Investigate asphalt materials on the nano-scale, including how RAP/RAS materials can be recycled and how asphalt materials can self-heal and rejuvenator selection
Book Synopsis Assessment of the Impact of Fiber Types on the Performance of Fiber-Reinforced Hot Mix Asphalt by : Christopher J. DeCarlo
Download or read book Assessment of the Impact of Fiber Types on the Performance of Fiber-Reinforced Hot Mix Asphalt written by Christopher J. DeCarlo and published by . This book was released on 2020 with total page 11 pages. Available in PDF, EPUB and Kindle. Book excerpt: This study aims to evaluate the impact of fiber types on the performance of hot mix asphalt (HMA) mixtures. Specifically, the impacts of fiber type on HMA mix design and laboratory performance are investigated. Four types of fiber (fiberglass, basalt, carbon, and polyolefin/aramid blend) were used to produce four fiber-reinforced HMA mixes, and a control mix without fibers was also prepared. The fiber dosage rates used in this study were 0.16% (fiberglass, basalt, and carbon) and 0.05% (polyolefin/aramid) by total mixture weight, based on manufacturer recommendations. Two mixing procedures for introducing fibers into HMA were also evaluated: dry and 15-s dispersion methods. The dry method involved mixing the fibers with aggregates before the addition of asphalt binder while the 15-s dispersion method involved adding the fibers into the mix every 15 seconds (as aggregates were coated by asphalt binder during the mixing process). All the HMA mixtures (unreinforced and fiber-reinforced) were then subjected to several different laboratory performance tests: dynamic complex modulus, Cantabro durability, asphalt pavement analyzer, flow number, and indirect tensile strength. Analysis of variance was conducted to evaluate statistically the impact of fibers on mix performance. Results showed that fibers affected the volumetric properties, mix durability, and rutting resistance of HMA mixes. It was also found that the process for introducing fibers into the mix (i.e., mixing method) affected the consistency of fiber-reinforced HMA samples. Overall, the results of this study showed that the use of fibers improved the rutting and durability performance of asphalt mixtures in the laboratory.

Book Synopsis Recycled Plastic Fibers for Asphalt Mixtures by : Mohammed L. Labib
Download or read book Recycled Plastic Fibers for Asphalt Mixtures written by Mohammed L. Labib and published by . This book was released on 1999 with total page 98 pages. Available in PDF, EPUB and Kindle. Book excerpt: The use of recycled fibers in asphalt mixtures was found to be beneficial in some cases only such as when fishing nets were used. The final conclusion of the program was to pursue a systematic study primarily based on using the Superpave design schedule. The final approach was to use virgin fibers first to clearly understand how fibers affect the mechanical properties of the mixture, and then apply the results to the use of recycled fibers -- all the work was to follow the Superpave design approach. A comprehensive review of the results is included in this report.

This book was released on 2016 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: The premature deterioration of hot mix asphalt pavements is one of the common issues concern many transportation agencies. Innovative solutions are needed to enhance the serviceable life of pavement. Various techniques are widely utilized. One of the most popular and common methods is fiber reinforcement. Fibers have been used extensively in Portland Cement Concrete (PCC) since 1950's. However, use of fibers in asphalt mixtures is relatively new. There are limited studies that investigate the effect of fibers in asphalt mixtures. Some laboratory testing showed that fibers improved the resistance of asphalt mixtures to rutting and fatigue. However, these investigations did not provide a comprehensive understanding of the interaction mechanism between asphalt mixture constituents and fibers. The goal of this research was to evaluate and quantify the effect of fibers on the mix performance characteristics. Furthermore, the research aimed at evaluating the healing characteristics, developing a method to detect the fiber dispersion in the mix and to develop a finite element model (FEM) to study the resistance of fiber-modified asphalt mixtures to permanent deformation. Three types of synthetic fibers were used. Fiber #1 (aramid and polyolefin fibers), fiber #2 (a wax treated aramid fiber) and fiber #3 (glass fiber). A number of laboratory tests were conducted on laboratory-prepared test samples and extracted field cores. A FEM model to simulate the accelerated performance test was developed and was calibrated using material parameters from direct laboratory testing. X-ray tomography was used to evaluate and quantify the level of fiber dispersion in the mix. The results show slightly improved performance at higher fiber contents than those recommended by the manufacturers. Asphalt healing study revealed that presence of fibers has increased healing rate and consequently delayed fatigue damage. The developed finite element model (FEM) can be used to predict a long-term rutting performance of asphalt pavements. It was found out that X-ray tomography was not suitable to detect fiber dispersion. An optical image processing technique in conjunction with a lab-based method using UV light was developed and found to be more successful to evaluate the fiber dispersion in the mix.
