Book Description
Cold in-place recycling (CIR) using asphalt emulsion is a cost-effective method for the preventive and corrective maintenance of existing pavements. The objectives of this study were to evaluate the recycling mixture's macroscopic performance and to analyze the microstructure of the mastics using a scanning electron microscope (SEM). The overall performance of the recycling material was evaluated for retained stability, immersed freeze-thaw indirect tension tests, and rut testing. Additionally, the surface micro-profiles of three mastic classes were analyzed using SEM. The results of the bulk property analyses indicated that the addition of cement improved the performance of the recycling mixtures. The SEM analyses showed that cement has an effect similar to fiber-reinforcement in cement-treated asphalt emulsion CIR mixtures. Further, the results indicated that the mechanism of cement action is consistent with the results of the overall mixture performance properties.

Book Description
The Kansas Department of Transportation (KDOT) by cold in-place recycling (CIR) recycles approximately 120 to 160 km of pavement a year as a part of their 1-R maintenance program. Originally KDOT utilized asphalt emulsions (AE) as the additive in CIR mixtures, but based on performance concerns currently utilizes type C fly ash. Recent research indicates that the use of CIR with asphalt emulsion and hydrated lime, introduced as hot slurry, provides improved performance. KDOT constructed two test sections on US-283 using type C fly ash and CSS-1 with hot lime slurry and type C fly ash. Two additional asphalt emulsions were evaluated as well, CMS-1 and HFE-150. The cores and laboratory samples were tested for tensile strength, AASHTO T283, resilient modulus and for rutting resistance and moisture damage using the Asphalt Pavement Analyzer (Georgia Rut Tester).

Book Description
Eco-efficient Pavement Construction Materials acquaints engineers with research findings on new eco-efficient pavement materials and how they can be incorporated into future pavements. Divided into three distinctive parts, the book emphasizes current research topics such as pavements with recycled waste, pavements for climate change mitigation, self-healing pavements, and pavements with energy harvesting potential. Part One considers techniques for recycling, Part Two reviews the contribution of pavements for climate change mitigation, including cool pavements, the development of new coatings for high albedo targets, and the design of pervious pavements. Finally, Part Three focuses on self-healing pavements, addressing novel materials and design and performance. Finally, the book discusses the case of pavements with energy harvesting potential, addressing different technologies on this field. - Offers a clear and concise lifecycle assessment of asphalt pavement recycling for greenhouse gas emission with temporal aspects - Applies key research trends to green the pavement industry - Includes techniques for recycling waste materials, the design of cool pavements, self-healing mechanisms, and key steps in energy harvesting

Book Description
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. - Provides a comprehensive and in-depth coverage of the science and technology of polymer modified bitumen - Focuses on the preparation and properties of a range of polymer modified bitumen, including emulsions, modification of bitumen with poly(urethanes), waste rubber and plastic as well as polypropylene fibres - Addresses the characterization and properties of polymer modified bitumen, including rheology, simulated and actual long term ageing studies, and the solubility of bituminous binders in fuels
