Concurrently, environmental concerns and recycling processes are becoming a part of our everyday life. Tall oil pitch (TOP) is a by-product of the kraft process in the pulp and paper industry. The company's research and development team has conducted development programs and intensive testing of physical properties of tall oil pitch modified asphalt cement binders. Obtained results show that tall oil pitch strongly influences the rheological properties of asphalt cement. These blends have higher penetration, lower viscosity, and are more temperature susceptible than original asphalt cement. Blends also have excellent wetting properties of aggregate.

DOWNLOAD EBOOK →Detailed data were collected from field and laboratory evaluations to determine whether changes in crude oils affect the physical and chemical properties of asphalt binders over time. The test results indicated that asphalt cement properties produced today have the same range of values as those produced in the 1990s. Asphalts with high-viscosity susceptibility were shown to be associated with pavement distress. Field evaluations showed that asphalts with a viscosity susceptibility value lower than 0.088 will perform well without premature failure. Asphalts containing relatively low asphaltenes, particularly those of softer grade, appeared to have a greater probability of producing mixtures that could lead to pavement distress. Data analyses revealed that a good knowledge of the physical characteristics and chemical composition of asphalts can provide a useful tool for distinguishing between asphalts associated with pavement performance.

DOWNLOAD EBOOK →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
