Arabian Journal for Science and Engineering. In recent years, nanomaterials have led to promising developments in the improvement of pavement performance. In this study, characterisation of nanocomposite-modified binders using Fourier transform infrared spectroscopy FT-IR , field emission scanning electron microscopy FE-SEM , and dynamic shear rheometer was investigated. The study investigates the application of response surface methodology RSM to develop models and determine optimum proportions for higher linear viscoelastic properties. FT-IR spectroscopy confirms chemical reaction between nanosilica- and polypropylene-modified bitumens, which resulted in a reduction in oxidative hardening of the modified binders. FE-SEM analysis for the modified binders shows a good dispersion of polypropylene and nanosilica within the modified binder matrix.
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. 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.

This is our standard polymer modified bitumen system. At the heart of the system lies our multi stage high shear PMB mill which shears polymers effectively. Due to the fast pace of development in the United Arab Emirates 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 Composition of polymer modified bitumen is bitumen plus polymer and a compatibilizing agent prepared by reacting one or more unsaturated monomers with a bituminous composition comprising asphaltenes or resins. The basic laying workability of the asphalt or macadam you are using will still be governed by the viscosity of the grade of bitumen you have specified.
