Summary

As one of the commonly used construction materials in pavement engineering, bitumen produced from refining specific crude oils is usually used as a binder to produce the bituminous mixture with aggregates and mineral powders. During the long-term service, bituminous mixtures are frequently subjected to diseases, including rutting, fatigue, de-bonding, etc., under the influence of the environment and traffic loading. The above diseases are closely related to the variations in the rheological properties of bitumen. Thus, clarifying the rheological behaviors of bitumen is necessary to deeply understand the damage mechanism of bituminous mixtures.

The special issue aims to deeply understand the rheological properties of bitumen and bituminous mixtures. The most interesting topics-but are not limited to-for this special issue are as follows:

● Relationships between rheology and chemistry of bitumen.

● Rheology for the heterogeneous system of polymer modified bitumen.

● Effects of environmental and loading conditions on rheological properties of bitumen and bituminous mixtures.

● Damage mechanism evaluation of bitumen and bituminous mixtures based on their rheological characteristics.

    Physical-Rheological Properties and Performances of Rejuvenated (Styrene-Butadiene-Styrene) Asphalt with Polymerized-MDI and Aromatic Oil

    FDMP-Fluid Dynamics & Materials Processing, Vol.20, No.7, pp. 1633-1646, 2024, DOI:10.32604/fdmp.2024.051010

    Abstract Traditional asphalt rejuvenators, like aromatic oil (AO), are known to be effective in improving the low-temperature properties and fatigue performances of aged SBS (styrene-butadiene-styrene) modified asphalt (SBSMA) binders and mixtures. However, these rejuvenators inevitably compromise their high-temperature properties and deformation resistances because they dilute asphalt binder but do not fix the damaged structures of aged SBS. In this study, a highly-active chemical called polymerized 4,4-diphenylmethane diisocyanate (PMDI) was used to assist the traditional AO asphalt rejuvenator. The physical and rheological characteristics of rejuvenated SBSMA binders and the moisture-induced damage and rut deformation performances of corresponding… More >
