Book Description
Recycling of waste plastic is an issue of great concern worldwide because of its considerable quantity and growth. The effects of waste polyethylene (PE) on the rheological properties of asphalt binder were investigated in this research. Three types of PE were adopted to prepare modified binders with contents ranging from 2 to 6 %. A viscosity test, performance grade test, frequency sweep test, amplitude sweep test, and linear amplitude sweep test are conducted to study rheological properties of PE modified binders, compared with base binder and binders modified with styrene-butadiene-styrene and crumb rubber modifier. The test results indicated that the high temperature properties of asphalt binders could be effectively improved by the PE modifiers with different types and contents. The high temperature grade and rutting resistance factor of PE modified binder can be increased significantly when compared with the base binder. With the increased PE content, the complex modulus increased, whereas the phase angle values decreased in most test frequencies and shear strain, which implied that the usage of PE not only reinforced the viscosity of binders but also enhanced the elasticity. The fatigue properties of PE modified binders were improved, especially at the lower shear strain range. However, PE modifier had a negative effect for asphalt binder on low temperature property.

Book Description
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.

Book Description
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.

Book Description
Highway engineers are facing the challenge not only to design and construct sustainable and safe pavements properly and economically. This implies a thorough understanding of materials behaviour, their appropriate use in the continuously changing environment, and implementation of constantly improved technologies and methodologies. Bituminous Mixtures and Pavements VII contains more than 100 contributions that were presented at the 7th International Conference ‘Bituminous Mixtures and Pavements’ (7ICONFBMP, Thessaloniki, Greece 12-14 June 2019). The papers cover a wide range of topics: - Bituminous binders - Aggregates, unbound layers and subgrade - Bituminous mixtures (Hot, Warm and Cold) - Pavements (Design, Construction, Maintenance, Sustainability, Energy and environment consideration) - Pavement management - Pavement recycling - Geosynthetics - Pavement assessment, surface characteristics and safety - Posters Bituminous Mixtures and Pavements VII reflects recent advances in highway materials technology and pavement engineering, and will be of interest to academics and professionals interested or involved in these areas.
