The addition of polymers to bitumen allows the modification of certain physical properties, such as softening point, brittleness and ductility, of the bitumen. Polymer modified bitumen: Properties and characterisation provides a valuable and in-depth coverage of the science and technology of polymer modified bitumen. After an initial introduction to bitumen and polymer modified bitumen, the book is divided into two parts. Chapters in part one focus on the preparation and properties of a range of polymer modified bitumen, including polymer bitumen emulsions, modification of bitumen with poly (urethanes), waste rubber and plastic and polypropylene fibres. Part two addresses the characterisation and properties of polymer modified bitumen. Chapter topics covered include rheology, simulated and actual long term ageing studies; the solubility of bituminous binders in fuels and the use of Fourier transform infrared spectroscopy to study ageing/oxidation of polymer modified bitumen. Polymer modified bitumen is an essential reference for scientists and engineers, from both academia and the civil engineering and transport industries, interested in the properties and characterisation of polymer modified bitumen.

Characterization Of Polymer Modified Asphalt Binders Containing Processed Oil written by Navid Hemmati and has been published by this book supported file pdf, txt, epub, kindle and other format this book has been release on 2023 with Pavements categories.

The current study investigates the impact of processed oil on asphalt binder PG 64-22 and conjugate of it with common modifiers such as Crumbed Rubber Modifier (CRM), Styrene-Isoprene-Styrene (SIS), Styrene-Butadiene-Styrene (SBS) and Petroleum Resin (PE). The binder was tested at different temperatures, and different amounts of modifiers and processed oil were added to the binder. The modified binders were also aged artificially using different procedures. The study found that adding processed oil to polymer modified binders reduces viscosity and improves workability, while the modifiers improve the rutting resistance of them, however, the addition of processed oil reduces the binder's rutting performance due to decrement of viscosity. The study also found that the conjugating of modifying polymers and processed oil improves the low temperature cracking resistance. The study's results indicate that co-modifying polymer binders with processed oil resulted in a significant reduction in viscosity values, resulting in improved workability. The results also showed that increasing the processed oil concentration from 6% to 12% caused a viscosity reduction in conjugation of CRM, SIS, SBS and PE. Even though the addition of processed oil results in a reduction in the rutting performance of asphalt binder, the addition of polymers significantly improved the rutting resistance of asphalt binders. The modified asphalt binders containing 6% and 12% processed oil decreased the G*sin ð values. This reduction caused improvement of fatigue cracking resistance of all binders modified with CRM, SIS, SBS and PE. The higher concentration of processed oil means 12% showed greater reduction rate compared to the asphalt binders containing 6% processed oil. The BBR results for modified asphalt binders showed that the incorporation of CRM, SIS, SBS and PE and processed oil improved the low temperature cracking resistance significantly, due to the high penetration rate of processed oil in asphalt binders during modification.

Substantially improved overlay mixes, required by the modern road industry should be highly resistent to reflection cracking. The mix must contribute significantly to the stiffness of the pavement, even when it is applied in relatively thin layers. The binder should possess a high softening temperature to reduce the sensitivity for rutting and corrugation, and it should have a reasonable penetration value to minimize the chances of cracking. In this paper attention is paid to the manner SBS polymer modified asphalt binders cope with this set of requirements. The basic principles of this modification are outlined and emphasis is laid on the rheological and mechanical properties: viscosity and penetration test results are presented. Burgers' model for viscoelastic materials is used in an attempt to describe the visco elasticy. Results of indirect tensile tests are reported, including the tensile strengths and the elastic moduli. Repeated loading tests have been done on polymer modified and plain asphaltic concrete mixes. The results are mutually compared concerning fatigue behaviour, elastic moduli and crack propagation characteristics. The paper describes various trial sections, with special attention to comparative tests carried out in an Australian accelerated loading facility.

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

Asphalt modification is an important area in the development of new road and pavement materials. There is an urgent demand for road materials that can minimize fracture at low temperatures and increase resistance to deformation at high temperatures. The function of asphalt is to bind aggregate to protect it from water and other harmful agents. In the beginning asphalt was ideal for this purpose, but recently traffic loads have increased and environmental factors have deteriorated more rapidly than before. Asphalt is a byproduct of crude oil in the refining process, and it is considered a complex heterogeneous mixture of hydrocarbons. Asphalt modification has become an important research area, using several methods and new materials as modifiers.
