Book excerpt: The objective of this study was to evaluate the material properties of a conventional (control) and fiber-reinforced asphalt mixtures using advanced material characterization tests. The laboratory experimental program included triaxial shear strength, dynamic (complex) modulus, repeated load permanent deformation, fatigue, crack propagation, and indirect tensile strength tests. The data was used to compare the performance of the fiber-modified mixture to the control. The results showed that the fibers improved the mixture's performance in several unique ways against the anticipated major pavement distresses: Permanent deformation, fatigue cracking, and thermal cracking.

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.

This book was released on 2018-02-01 with total page 320 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents the detailed results of five task groups of the RILEM technical committee TC 237-SIB on Testing and Characterization of Sustainable Innovative Bituminous Materials and Systems. It concentrates on specific new topics in asphalt binder and mixture testing, dealing with new developments in asphalt testing, in particular also in view of new innovative bituminous materials, such as hot and cold recycled mixtures, grid reinforced pavements and recycled Reclaimed Asphalt Pavements (RAP), where test methods developed for traditional asphalt concrete are not a priori applicable. The main objective is providing a basis for pre-standardization by comparing different test methods and showing ways for fundamental improvements. Thus, the book also points the way for a further advanced chemo-physical understanding of materials and their role in pavement systems relying on fundamental material properties and suitable models for describing and predicting the intrinsic mechanisms that determine the material behavior.

Available in PDF, EPUB and Kindle. Book excerpt: This report summarizes the results of a research project that was conducted to evaluate the cracking resistance of aramid fiber-reinforced asphalt mixes used for resurfacing applications on local roads and compare it to that of polymer-modified asphalt mixes. This project was divided into two phases. Based on the results of laboratory study in Phase 1, fifteen test sections were constructed during 2020 construction season as part of five projects in the City of Columbus, Fayette County, and the City of Kettering. Two aramid fiber types, one with 0.75 in. (Fiber B) and the other 1.5 in. length (Fiber A) from different sources, were used for this project. During the construction of the test sections, loose asphalt mixtures and field cores were collected for evaluation in the laboratory using semi-circular bend (SCB), indirect tensile asphalt cracking test (IDEAL-CT), and asphalt concrete cracking device (ACCD). The results of laboratory tests conducted on field cores and field-produced laboratory compacted samples indicated that the effects of addition of aramid fiber to asphalt mixture vary depending on binder grade, binder type, and mix type. In general, Fiber A and Fiber B improved the cracking resistance of mixes with PG 64-22. Mixes with PG 64-22 binder and aramid fibers had similar cracking resistance to those with PG 70-22M asphalt mix. Fiber A improved the cracking resistance for mixes with PG 58-28 binder. In addition, Fiber B improved the indirect tensile strength for mixes with PG 58-28 and had similar cracking resistance as those with PG 64-22. The fibers did not improve the low-temperature cracking resistance of asphalt mixes. The statistical analysis of the test results indicated that the properties related to the cracking resistance of the fiber mixes did not significantly change during the different production days.

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.
