Modification mechanism of asphalt modified with Sasobit and Polyphosphoric acid (PPA)

Construction and Building Materials, 2017
Abstract 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

Evaluation of the conventional and rheological properties of SBS + Sasobit modified binder

Construction and Building Materials, 2014
Abstract The effort of constructing durable roads with higher standards has required to research the usage of various additives in bituminous coating so far. Nowadays polymer modification is effectively applied, and additives, which can provide better compaction and less expense by improving workability features are considered.

Study on the Impact of Sasobit on Asphalt’s Temperature Susceptibility

Key Engineering Materials, 2011
In order to evaluate the impact of Sasobit on asphalt, the 2%,3%,4% and 5% Sasobit by mass of asphalt are blended into two types of base asphalts (Pen 60/80 and SBS modified asphalt).The mixed asphalt will be called as Sasobit modified asphalt in this study.

Effects of Sasobit on Rheological Properties of Asphalt Binders

Key Engineering Materials, 2012
Research 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

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.

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.

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
