Book excerpt: Chemical aging of asphalt binder leads to significant changes in its mechanical and rheological properties, resulting in poor pavement behavior and distress. Various laboratory methods have been used to simulate asphalt aging during the service life of the pavement. However, controversy exists regarding the capability of these methods to predict field aging, as various factors interact with the pavement during service and the mechanism behind aging is not fully understood. The two main outcomes of chemical aging are oxidation of asphalt molecules, and change in asphalt SARA (saturate, aromatic, resin, and asphaltene) fractions. Reaction of oxygen with asphalt components forms polar viscosity-building molecules, while the change in SARA fractions upsets the balance in asphalt, giving it brittle properties. As both these factors affect the binder at the molecular level, molecular dynamic (MD) simulations can provide core insights into understanding the fundamentals of asphalt aging. This study used MD simulation to investigate the effect of each aging process on the properties of asphalt binder. In that respect, a representative model of virgin binder and eight different models of aged binder were built, including models for laboratory- and field-aged binder. Properties such as density, bulk modulus, glass transition temperature, and viscosity from different MD models were compared to distinguish between the effect of each aging mechanism on binder properties. The results showed that both aging mechanisms lead to an increase in density, bulk modulus, and viscosity of the binder. The SARA fractions of laboratory-aged binder were found to affect bulk modulus and viscosity more dramatically compared to field aged binder. However, when the oxygen content of models was considered, field-aged binder showed a larger increase in bulk modulus and viscosity compared to laboratory-aged binder. This indicates that the dominant mechanism from laboratory aging process is upset in SARA fractions, while oxidation of molecules might be a more dominant mechanism for field-aged binder. No statistically significant difference was observed between the glass transition temperature values for virgin and aged binder.

Book excerpt: Engineering technology is of crucial importance to the infrastructure on which modern societies depend, and keeping abreast of the latest research and developments in the field is of vital importance. This book presents the proceedings of HCET 2022, the 7th International Technical Conference on Frontiers of Hydraulic and Civil Engineering Technology, originally due to be held, in Sanya, China, from 25-27 September 2022, but instead held as a fully virtual event on Zoom due to continued uncertainty related to the Covid 19 pandemic. HCET is a platform for the dissemination of research results on the latest advances in the areas of hydraulic and civil engineering technology and environmental engineering, and provides an opportunity for scientists, researchers and engineers from around the world to exchange their findings, discuss developments, and possibly establish a basis for collaboration. A total of 275 submissions were received from international contributors, and all were subjected to a rigorous peer-review process, with each paper reviewed by a minimum of two experts. Papers were also checked for quality and plagiarism, after which, 163 papers were accepted for presentation and publication. Topics covered include the research and development of concrete structure design and analysis, structural mechanics and structural engineering, geological exploration and earthquake engineering, building technology, urban planning, energy, environment and advanced engineering science and applications. The book offers a state-of-the-art overview of recent developments, and will be of interest to all those working in the fields of hydraulic and civil engineering technology.

Available in PDF, EPUB and Kindle. Book excerpt: As global consumption of fossil fuels such as oil increases, previously abundant sources have become depleted or plagued with obstructions. Asphaltene deposition is one of such obstructions which can significantly decrease the rate of oil production. This book offers concise yet thorough coverage of the complex problem of asphaltene precipitation and deposition in oil production. It covers fundamentals of chemistry, stabilization theories and mechanistic approaches of asphaltene behavior at high temperature and pressure. Asphaltene Deposition: Fundamentals, Prediction, Prevention, and Remediation explains techniques for experimental determination of asphaltene precipitation and deposition and different modeling tools available to forecast the occurrence and magnitude of asphaltene deposition in a given oil field. It discusses strategies for mitigation of asphaltene deposition using chemical inhibition and corresponding challenges, best practices for asphaltene remediation, current research, and case studies.

This book was released on 1993 with total page 164 pages. Available in PDF, EPUB and Kindle. Book excerpt: Nuclear magnetic resonance (NMR) spectroscopy was used in solution-state and solid-state experiments on 8 asphalt cements. Using a variety of chemical and solution-state NMR spectroscopic techniques, data were obtained about the amounts of aromatic carbon in an average molecule of asphalt sample, how the carbon is arranged in terms of size of the average aromatic system and the extent of substitution. By using solid-state NMR spectroscopic techniques, the structure of asphaltic cements was probed on a small-distance scale. Difference in molecular mobility were found among the asphalts studied. Changes in molecular mobility after laboratory oxidative aging were found to be small. The implications of these data with regard to the 'micellar model' of asphalt are discussed. The research results' potential impact on understanding asphalt cement properties is explored.
