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.
