Testing and Evaluation of Sasobit on the Performances of Asphalt Rubber

ICCTP 2011, 2011
Different doses of Sasobit were added into Asphalt Rubber, their penetrations, softening points, ductility's at low temperature and viscosities were measured. The test results indicate that Sasobit can reduce Asphalt Rubber's penetration and increase its softening point, improving the high-temperature performance. It was also indicated that Sasobit has

The Experimental Research on Durability of Sasobit Modified Asphalt

Advanced Materials Research, 2011
Sasobit 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.

Warm Mix Asphalt Using Sasobit in Cold Region

Cold Regions Engineering 2009, 2009
The potential of using Warm Mix Asphalt (WMA) in reducing the energy consumption of hot mix asphalt (HMA) is becoming more and more attractive nowadays. The goals for the WMA are to lower mixing and compacting temperatures and use the same Hot Mix Asphalt (HMA) plants to produce mixes that still meet specifications.

Rheological Property Investigation of Various Sasobit-modified Bitumen

Petroleum Science and Technology, 2015
Sasobit 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

Study on the Impact of Sasobit on Asphalt's Properties and Micro-Structure

Pavements and Materials, 2010
In this study, Sasobit was used as an additive into asphalt. Different ratios of Sasobit were blended into base asphalt Pen. 60/80. The conventional tests, such as penetration test, softening point test, viscosity test, and constituent test, were carried out on asphalt mixed with different additive contents.

Low Temperature Performance of Sasobit-Modified Warm-Mix Asphalt

Journal of Materials in Civil Engineering, 2012
In 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

Evaluation of Sasobit Warm Mix Rubber Asphalt Properties

ICTE 2011, 2011
As 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 ...

Coupled Effects of Gilsonite and Sasobit on Binder Properties: Rheological and Chemical Analysis

Journal of Materials in Civil Engineering, 2022
Experiences of highway agencies show that the costs of repairing rutting distresses are high. The common solution to overcome this issue is using a modified asphalt binder. The modifier enhances the asphalt binder's rheological and physical properties but increases the production temperatures of asphalt pavement.

Research on the Performances of Warm Asphalt and Warm Mix Asphalt with Sasobit

ICCTP 2010, 2010
This paper studied the impact of Sasobit on the performance of asphalt and asphalt mixtures. The normal performance tests on asphalt indicate that when the quantity of Sasobit increases, the penetration index (PI) and the softening point increases; but the penetration and the ductility in the low temperature range reduces.
