The dynamic mechanical behaviour of bitumen (BIT)modifaed with styrene-butadiene-styrene bloc copolymer (SBS) were investigated. dynamic mechanical analysis (DMA) were performed in the temperature range -100 to 100 C. The primary viscoelastic function were determined at the traffic frecuency, 5 Hz.

Thermal fatigue of polymer modified bitumen
Journal of Thermoplastic Composite Materials, 2011Thermal fatigue is a serious distress in flexible pavement that reduces performance and durability. Many researchers have made efforts to understand the thermal fatigue phenomenology. Until now, there has not existed a standard test method for evaluating mixture and binder resistance to thermal fatigue.

Photocatalytic activity of neat and polymer-modified bitumen
Applied Materials Today, 2020Abstract In recent years, the implementation of inorganic photocatalysts in road-paving materials has been explored as a promising solution for the degradation of volatile pollutants produced by both automotive vehicles and civil/industrial activities. However, this study shows that asphalt binders, an essential component of asphalt mixtures, already

The impact of chaotic advection on the microstructure of polymer‐modified bitumen
AIChE Journal, 2014Owing to the high viscosity of the materials involved, mixing is often a critical step when processing polymer‐modified bitumen (PMB), directly influencing the microstructure and the stability of final products. We provide experimental evidence suggesting that laminar chaotic advection may prove a valuable strategy for obtaining a homogeneous and ...

Chapter 16 Polymer-Modified Bitumen
1994Publisher Summary A wide range of modified bitumens are available to meet various challenges faced by the engineer. This chapter describes the role of bitumen modifiers, types of polymeric modifiers, influence of bitumen constitution, manufacture of the polymer-modified bitumens, properties of polymer-modified bitumens, and products and applications.

Evaluation of fatigue parameters on polymer modified waxy bitumens
2019© 2019 Taylor & Francis Group, London.Since exact behaviour of waxes within bitumens is not completely determined and the absence of cooperative study related to modification of bitumens involving different amounts of waxes, the values found in the study are thought to be useful in determining which type of polymer would be better in terms of fatigue ...

TERMOXIDATIVE AGING OF POLYMER MODIFIED BITUMEN
2014Bitumen aging resulting in hardening of bitumens and embrittlement, both in application and in service, contributes greatly to the deterioration of paving application. Aging is a very complex process of bitumen ; BIT and the complexity increase when polymers are involved in polymer modified bitumens, PmBs.

CREEP&RECOVERY-POLYMER MODIFIED BITUMEN
2013Rutting, defined as accumulated permanent deformation, is a common form of distress in asphalt pavements. Rutting failure leads to poor serviceability of the pavements, making vehicles ride rough and unsafe. The increasing demands of traffic on road building materials in recent years has led to the evaluation, development and use of a wide range of ...

Rheological properties of polymer modified bitumen
2013U radu je istražen utjecaj različitih inaktivnih i aktivnih polimera iz skupine elastomera i plastomera na reološka svojstva polimerom modificiranog bitumena, PmB, i trajnu deformaciju pod oscilirajućim smičnim opterećenjem u ovisnosti o temperaturi i frekvenciji. Rezultati reoloških ispitivanja uspoređeni su s određenim fizikalnim svojstvima. Reološka
