Download or read book Plastic Waste for Sustainable Asphalt Roads written by Filippo Giustozzi and published by Woodhead Publishing. This book was released on 2022-01-13 with total page 406 pages. Available in PDF, EPUB and Kindle. Book excerpt: Waste polymers have been studied for various applications such as energy generation and biochemical production; however, their application in asphalt roads still poses some questions. Over the last decade, several studies have reported the utilization of waste plastics in roads using different methodologies and raw materials, but there is still significant inconsistency around this topic. What is the right methodology to recycle waste plastics for road applications? What is the correct type of waste plastics to be used in road applications? What environmental concerns could arise from the use of waste plastics in road applications? Plastic Waste for Sustainable Asphalt Roads covers the various processes and techniques for the utilization of waste plastics in asphalt mixes. The book discusses the various material properties and methodologies, effects of various methodologies, and combination of various polymers. It also provides information on the compatibility between bitumen and plastics, final asphalt performance, and environmental challenges. - Discusses the processes and techniques for utilization of waste plastics in asphalt mixes. - Features a life-cycle assessment of waste plastics in road surfaces and possible Environmental Product Declarations (EPD). - Includes examples of on-field usage through various case studies.

This book was released on 2002 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: ABSTRACT (cont.): Analysis of test results in this study indicate that excessive asphalt binder may have been used in order to meet the voids in mineral aggregates (VMA) criteria for the poor performing mixtures. This finding may be consistent with other related findings that suggest that for some coarse graded aggregate structures, addition of so much asphalt binder may be necessary to meet the current Superpave VMA specification. The VMA requirement should, therefore, be reviewed. It is also found in this study that for mixtures with excessive asphalt binder the aggregate structure may not significantly affect the rutting resistance of the mixture. This may be the case because the asphalt binder tends to have a predominant influence, especially at higher temperatures, reduces the aggregate particle interaction in the mixture and, therefore, leads to poor rutting performance. The study finds that there may be apparent relationships between rutting resistance of mixtures and the following laboratory measured parameters: (1) the rate of change of gyratory shear per cycle measured from the slope of the gyratory shear versus number of cycles (semi-logarithm scale) in the Servopac Gyratory Compactor, (2) the rut depth measured in the Asphalt Pavement Analyzer and (3) the gyratory stability index measured from the Gyratory Testing Machine.

Download or read book Methods to Achieve Rut resistant Durable Pavements written by Gerald A. Huber and published by Transportation Research Board. This book was released on 1999 with total page 72 pages. Available in PDF, EPUB and Kindle. Book excerpt: This synthesis report will be of interest to state, local, and federal agency pavement materials, design, and construction engineers, as well as pavement research engineers and scientists. Those with supervisory oversight for pavement programs will also find it of interest. It describes the current practice for methods to achieve rut-resistant durable pavements. The synthesis documents current experience with permanent deformation of asphalt pavements and identifies methods to improve performance. Information for the synthesis was collected by surveying U.S. and Canadian transportation agencies and by conducting a literature search using domestic and international sources. This report of the Transportation Research Board describes the extent of the rutting problem on the National Highway System, pavement mixture design issues, and the design of rut-resistant mixtures. In addition, alternate mixture types, including stone matrix asphalt and porous asphalt, are discussed, as well as international approaches to mixture design. Finally, the construction of rut-resistant mixtures, including the role of quality control and quality assurance methods, are discussed. A summary of permanent deformation causes and solutions is included in the appendix.

This book was released on 2004 with total page pages. Available in PDF, EPUB and Kindle. Book excerpt: Several compaction methods are used to fabricate specimens for performance testing in the laboratory. As the physical properties of the specimens depend on the method of compaction used for fabrication, the compaction methods adopted in the laboratory should simulate the properties of the pavement in the field. The effects of different compaction methods on the performance of mixtures were investigated in this study. Laboratory compaction methods such as Superpave Gyratory Compaction (SGC) and Rolling Wheel Compaction (RWC) were compared with field compaction. Four field mixtures were selected. Various performance evaluation tests were conducted on the field cores and specimens fabricated using SGC and RWC. The mixtures were evaluated using the Shear tester, the Asphalt Pavement Analyzer (APA) and the NCSU Wheel Tracking Device. The results indicate that the laboratory compacted mixtures tend to be superior in their performance than the field cores. The laboratory compacted mixtures have higher stiffness values and lower shear strain values than the field cores. The RWC seems to simulate field compaction better than the SGC. A good correlation was found between the results of the Repeated Shear tests at Constant Height tests, the APA tests and the NCSU WTD rut tests. The mixtures which failed to satisfy the RSCH test criteria had rut depths greater than 0.5 inch, as measured by the APA and NCSU WTD. The mixtures that passed the RSCH tests had rut depths less than 0.5 inch. The APA test and the NCSU WTD test can be used as a simulator to examine the rutting susceptibility of a mixture. The compactability of the mixtures is studied using the SGC, IPC Servopac Compactor and GLPA. The compaction parameters that relate with the rutting behavior of mixtures were compared with the RSCH shear strains at different air void contents. The correlations showed different trends with two sets of parameters with one set measuring the compactability of the mixtures and another set m.
