Diffusion Influence Mechanism of Virgin and Aged Asphalt Binder System Based on Molecular Dynamics
Publisher: American Society of Civil Engineers
Abstract: During the production and transport of reclaimed asphalt pavement (RAP), the diffusion of recycled aged asphalt binder and virgin asphalt binder can significantly affect the mechanical properties of the virgin and aged ...
Thermoregulation Performance and Mechanical Properties of Phase Change Asphalt Mortars
Publisher: American Society of Civil Engineers
Abstract: This study investigated the effects of a diatomite/tetradecane composite shaped phase change material (CSPCM) on the mechanical properties and thermoregulation performance of styrene-butadiene-styrene (SBS)- and ...
Molecular Dynamics Simulation and Experimental Study of Effective Ingredient Release Characteristics of Anti-Icing Modified Asphalt Mortar
Publisher: American Society of Civil Engineers
Abstract: Anti-icing asphalt pavement is widely used as an active snow melting technology for the purpose of weakening the effect of snow and ice hazards on road. However, most researches on anti-icing asphalt pavement focus on road ...
Topological Characterization and Typical Topologies of Disruption Aggregates in Asphalt Mixture
Publisher: American Society of Civil Engineers
Abstract: Mesoscale contact networks for asphalt mixtures play a crucial role in load resistance. However, there is a lack of quantitative characterization methods for contact networks. Topology can describe the contact relationships ...
Consideration of Heat Transfer Characteristics in Thermal Stress Calculations of Asphalt Mixtures in the TSRST
Publisher: American Society of Civil Engineers
Abstract: The low-temperature performance of asphalt mixtures was a critical factor that investigated the thermal cracking of asphalt pavement in cold regions of the world. Many scholars have affirmed that the failure temperature ...
Skeleton Filling System Evaluation Method of Asphalt Mixture Based on Compressible Packing Model
Publisher: ASCE
Abstract: Asphalt mixtures are composed of skeleton aggregate and filling mortar. Skeleton stability and mortar filling state are of great significance to asphalt mixture performance. First, the aggregate in asphalt mixture is ...
