Rheological Property Investigation of Various Sasobit-modified Bitumen
Petroleum Science and Technology, 2015Sasobit has gained interest as an alternative over polymer modification due to its capability of reducing energy requirements for asphaltic mix construction. A study was conducted in order to investigate the effect of different blending speeds on the rheological properties of bitumen at intermediate temperatures. Higher values of revolutions per minute

Low Temperature Performance of Sasobit-Modified Warm-Mix Asphalt
Journal of Materials in Civil Engineering, 2012In the summer of 2008, a field trial project using Sasobit-modified warm-mix asphalt (WMA) was established in Alaska, which was Alaska’s first experience with a WMA technology. Previous studies conducted by writers identified a number of engineering benefits of Sasobit-modified WMAs over conventional hot-mix asphalt (HMA). This paper presents a further

The Experimental Research on Durability of Sasobit Modified Asphalt
Advanced Materials Research, 2011Sasobit has been applied into asphalt successfully since 1997. From then on, a lot of studies emphasizes on how Sasobit can lower asphalt’s viscosity and reduce poison odor emission. However, the durability of asphalt containing Sasobit is ignored to research. This paper aimed to analyze Sasobit impact on the durability of asphalt.

Evaluation of Sasobit Warm Mix Rubber Asphalt Properties
ICTE 2011, 2011As a kind of compound modification materials, warm mix rubber asphalt (short for WMRA) has outstanding advantages of low carbon emission. Rubber powder and additive agent applied in it have different influence on the asphalt binder. However, due to no thorough and systematic studies on the influencing factors, there is a lack of clear guiding ideology ...

Effects of Sasobit on Rheological Properties of Asphalt Binders
Key Engineering Materials, 2012Research in the laboratory was carried out to determine if addition of warm mix asphalt additive (Sasobit) has potential to reduce the temperature comparison with control mix. To fulfill this purpose five types of asphalt binders have been produced with a Sasobit additive in concentration range from 0 to 10% by weight of the asphalt. Viscosity test and

Modification mechanism of asphalt modified with Sasobit and Polyphosphoric acid (PPA)
Construction and Building Materials, 2017Abstract The laboratory performance and modification mechanism of asphalt modified with Sasobit and Polyphosphoric acid (PPA) were studied through a comprehensive laboratory program. The base asphalt was mixed with 3% Sasobit to produce Warm Mix Asphalt (WMA) and then modified with four different percentages of PPA (0.5%, 1.0%, 1.5% and 2.0%) by mass
