Influence of the Instrumental Inertia Effect on the Asphalt Binder Oscillation Measurement
Publisher: American Society of Civil Engineers
Abstract: Inertia effect is an artifact commonly seen in the oscillation test for soft materials. It is due to the misattribute of the instrument’s elastic component to the sample’s properties, which will lead to overestimated storage ...
Study of Bonding Property of Warm Mix Asphalt Based on Binder Bond Strength and Molecular Dynamics Simulations
Publisher: ASCE
Abstract: The bonding property plays a crucial role in the durability of the asphalt mixture. Warm-mix asphalt (WMA) commonly is used for energy-efficient pavements. The addition of warm-mix additives makes the behavior of the bonding ...
Study on Moisture Diffusion Behavior in Asphalt Binder Based on Static and Dynamic Pore Water Conditions
Publisher: ASCE
Abstract: The current research on the moisture diffusion behavior in asphalt mostly discusses static water without considering dynamic pore water. In this paper, Fick, Two-stage, and Langmuir moisture diffusion models were used to ...
Assessment of Asphalt Aging Degree Using the Double Sigmoidal Rheological Master Curve Model
Publisher: American Society of Civil Engineers
Abstract: The master curve is widely used in the evaluation of rheological behavior asphalt. However, due to the complex rheological properties of high-viscosity modified asphalt (HVMA), its rheological properties change significantly ...
Laboratory Evaluation of the Effects of Long-Term Aging on High-Content Polymer-Modified Asphalt Binder
Publisher: ASCE
Abstract: One of the most widely used polymer-based modifiers in asphalt binders is styrene–butadiene–styrene (SBS), which results in binders of increased modulus, strength, toughness, and resistance to permanent deformation. These ...
