A temperature-independent methodology for bitumen modification evaluation based on DSR measurement

Bitumen is used worldwide in the construction of flexible pavements and because of its wide applicability its performance is needed to be improved in all regards like, Chemical, and thermal stability, fatigue life, moisture susceptibility, mechanical strength, temperature susceptibility, rutting resistance, ageing resistance, tensile strength, viscosity, stiffness etc. In this connection, researchers have used various modifiers to improve the pavement performance. The present paper provides a brief review of different modifiers in road making industry. Some popular polymer modifiers like low density polythene, high density polythene, polypropylene, ethyl vinyl acetate, styrene butadiene styrene and industrial waste are reviewed in terms of their role in bitumen modification. It also discusses enhancement in properties of bitumen after modification in order to improve properties of pavement. Through the reviewed literature, it is found that the addition of the polymers to bitumen tends to enhance fatigue and cracking resistance mainly. The future development and recommendation in modifiers for bitumen modification are also suggested in the end.

Bitumen Modification

This synthesis explores the state-of-the-knowledge and state-of-the-practice regarding the latest updates on polymer-modified bitumens (PmBs). The information in this study was gathered from a thorough review of the latest papers in the literatures related to modified bituminous materials, technologies, and advances. For this purpose, the paper is presented in two principle sections. In the first part, the bitumen itself is investigated in terms of chemical structure and microstructural systems. In the second part, the paper focuses on bitumen modification from different aspects for assessing the effectiveness of the introduced additives and polymers for enhancing the engineering properties of bitumen in both paving and industrial applications. In conclusion, the knowledge obtained in this study has revealed the importance of the chemical composition of base bitumen for its modification. It can be declared that while some polymers/additives can improve one or some aspects of neat bitumen properties, they can lead to compatibility problems in storage and production. In this respect, several studies showed the effectiveness of waxes for improving the compatibility of polymers with bitumen in addition to some benefits regarding warm mix asphalt (WMA) production.

Bitumen Modification

The study described in this paper focused on the possible use of waste products coming from the production of styrene–butadiene rubber (SBR) and polybutadiene rubber (PBR), as bitumen modifiers. Modified binders containing these products were prepared in the laboratory with different polymer dosages and were thereafter subjected to the evaluation of empirical and rheological properties. For comparative purposes, the study also considered SBR and PBR products of premium quality. Ageing effects were also taken into account by means of proper laboratory simulations. Obtained results indicated that the two types of polymer (SBR and PBR) have completely different effects on the rheology and expected performance of the resulting modified binders. In particular, while the two polymers showed similar effects in terms of resistance to permanent deformation, the SBR products proved to be superior from the viewpoint of fatigue resistance. However, only minor differences were found when comparing the effects produced by premium quality and waste polymers. As a result of the experimental findings, it was concluded that the use of waste SBR polymers can be an attractive solution for the production of affordable modified binders.
