Rheology of Asphaltic Binders and Their Effects on Asphalt Concrete

Transportation Research Record: Journal of the Transportation Research Board, 1996
The rheology of asphaltic binders and their effects on asphalt concrete are discussed with the intention of improving the correlation between conventional mix design results and pavement performance. Test results show that mineral fillers increase the viscosity and pseudoplasticity of asphalts but do not always decrease the tan 8, except apparently at ...

Low-Temperature Thermal Cracking of Asphalt Binder by Asphalt Binder Cracking Device

Transportation Research Record: Journal of the Transportation Research Board, 2006
An asphalt binder cracking device (ABCD) is proposed to determine the low-temperature cracking potential of an asphalt binder. ABCD is a simple test method; the operating principle is based on the differential thermal contraction between the metal ABCD ring and an asphalt binder placed outside the ring.

Modifying Complex Additive for Asphalt Binder

Chemistry and Technology of Fuels and Oils, 2016
© 2016 Springer Science+Business Media New York.The effect of modifying complex additives on the physicochemical properties of asphalt is studied. It is shown that complex additives based on cellulose fibers with surfactants adsorbed on their surfaces possess a cross-linking effect and improve the heat and frost resistance of the asphalt binder and its

Asphalt and binder evaluation of asphalt mix with 70% reclaimed asphalt

Road Materials and Pavement Design, 2017
With modern recycling technologies, reclaimed asphalt (RA) has been successfully used in new hot mix asphalt (HMA). However, even if the conventional technical specifications on binders and asphalt mixtures are met, HMA produced with high amount of RA, 50% and higher, may show poor performance behaviour.

Interaction nonlinearity in asphalt binders

Mechanics of Time-Dependent Materials, 2011
Asphalt mixtures are complex composites that comprise aggregate, asphalt binder, and air. Several research studies have shown that the mechanical behavior of the asphalt mixture is strongly influenced by the matrix, i.e. the asphalt binder. Characterization and a thorough understanding of the binder behavior is the first and crucial step towards ...

Thixotropic Characteristics of Asphalt Binder

Journal of Materials in Civil Engineering, 2011
Asphalt binder has thixotropic characteristics that significantly affect its overall performance, but specifically fatigue performance, healing performance, and high temperature performance. Therefore, a clear understanding of the thixotropy of asphalt binder, together with proper modeling, is useful in researching the performance of the material ...

Asphalt Binder for Recycled Asphalt Mixtures

Abstract: The present chapter provides a synthesis of the research activity of RILEM TC 264-RAP Task Group 3 (Asphalt Binder for Recycled Asphalt Mixtures). The binder component, virgin and recovered from reclaimed asphalt, as well as their combination and interaction with recycling additives commonly known as rejuvenators, were addressed. This chapter

Rheology and microstructure of asphalt binders

Rheologica Acta, 2001
The viscous and linear viscoelastic properties of different asphalt binders have been analyzed in this paper. Thus, an unmodified bitumen, a polymer-modified (SBS) bitumen, a commercial synthetic binder, and two model synthetic binders with different polymer (SBS) concentrations have been studied.

Detection of Polymers in Asphalt Binders

Transportation and Development Institute Congress 2011, 2011
Superpave™ performance-graded asphalt binder technology continues to advance with some producers focusing on the use of additives to enhance the performance of asphalt binders. A common practice is to modify an asphalt binder with a polymer to extend the high- and low-temperature range.

Thermorheological properties of asphalt binders

The Canadian Journal of Chemical Engineering, 2020
AbstractThe rheological properties of different types of asphalt binders were studied and compared considering their constituents and physical characteristics. The saturate, aromatic, resin, and asphaltene (SARA) analysis and differential scanning calorimetry (DSC) have shown their individual constituents and two distinct glass transition temperatures,
