Since polymer modified asphalt cement (PMAC) has been employed for a decade, the lifetime and wear of some of these pavements is reaching a stage where resurfacing will be necessary. This work describes the characterization of aged polymer modified bitumens to evaluate their potential for recycling. A tri-block co-polymer modified binder was selected and characterized usin.

The aged polymer modified asphalt (abbreviated as PMA) was recycled with two methods which were adding fresh .

The aged polymer modified asphalt (abbreviated as PMA) was recycled with two methods which were adding fresh PMA and adding recycling agent to investigate the recycling characteristics of PMA. The performance of the recycled PMA was evaluated systematically with a variety of indices, including penetration, softening point, ductility, viscoelasticity and stiffness. The history of bitumen polymer modification is described chronologically.

The physical properties and rheological properties of aged SBS modified asphalt cement were evaluated based on force-ductility test and SHRP binder tests. We also evaluated the recycling effectiveness of aged SBS modified asphalt under the presence or absence of rejuvenating agent, different mixing time and temperature.

Polymer modified bitumen: Properties and characterisation provides a valuable and in-depth coverage of the science . After an initial introduction to bitumen and polymer modified bitumen, the book is divided into two parts.

Polymer modified bitumen: Properties and characterisation provides a valuable and in-depth coverage of the science and technology of polymer modified bitumen. 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.

Characterization of aged polymer modified asphalt cements for recycling purposes /. Article. Polymer modification significantly alters the rheological characteristics of the binder, thereby requiring the use of fundamental rheological testing methods to provide an indication of the performance of the binder and subsequently the asphalt mixture.

This work describes the characterization of aged polymer modified bitumens to evaluate their potential for recycling. A tri-block co-polymer modified binder was selected and characterized using standard bitumen qualification techniques, i.e., the Superpave PG protocol. We developed a procedure to characterize the relative concentration of polymer in asphalt cements by gel permeation chromatography. Infrared spectrographic, thermogravimetric and rheological techniques were used to identify changes in the binder components as a result of aging. A correlation between field aging time and simulated aging by PAV was developed; PAV with humidity proved to be the best prediction. A comparison was established between the field aged materials and a series of lab aged binders. All binders were characterized with respect to their composition and rheological properties. In general, residual polymer was detected using gel permeation chromatography analysis except when extensive oxidative age hardening of the binder had occurred. Recycling of this material will require additives to restore the desired rheological properties to the binder blend.
