RAP Binder Influences on the Rheological Characteristics of Foamed Warm-Mix Recycled Asphalt
Publisher: American Society of Civil Engineers
Chemo-Rheological Characterization of Aging Behaviors of Warm-Mix High-Viscosity Modified Asphalt
Publisher: ASCE
Abstract: Today, high-viscosity modified asphalt (HVMA) is widely used in drainage asphalt pavements. However, due to its high construction temperature, HVMA is prone to thermal oxidative aging, which reduces its life cycle and ...
Rheological Properties of High-Viscosity Modified Asphalt Containing Warm-Mix Additives
Publisher: American Society of Civil Engineers
Abstract: High-viscosity modified asphalt (HVMA) is the most commonly applied method in drainage asphalt pavements. However, some disadvantages of hot-mix HVMA, including high energy consumption and unavoidable environmental pollution, ...
Diffusion Behavior of Rejuvenator and Its Influences on the Interfacial Properties of Recycled Asphalt Mixtures by Molecular Dynamics Simulations and Experiments
Publisher: ASCE
Abstract: In hot in-place recycled (HIR) technology, the in-place mixing paving construction method suffers from the problems of low mixing temperature and short mixing time, which lead to incomplete rejuvenator diffusion in waste ...
Repurposing Waste Polyurethane into Cleaner Asphalt Pavement Materials: Laboratory Investigation
Publisher: ASCE
Abstract: With the increasing consumption of polyurethane (PU) products, more and more waste polyurethane (WPU) needs to be handled, resulting in the inefficient utilization of post-consumer PU becoming a key problem in the recycling ...
Designing High-Performance Rejuvenators: A Theoretical Approach to Asphaltene Dimer Aggregation and Disaggregation
Publisher: ASCE
Abstract: The aging process of asphalt materials encompasses varying levels of oxidation reactions within its components. This process increases the polarity of the molecules, prompting aggregation among asphaltenes. Thus, a thorough ...
Investigation on the Diffusion Behavior of Dry Modified SBS at the Asphalt-Aggregate Interface: Molecular Simulation and Experiments
Publisher: ASCE
Abstract: Dry modified Styrene-Butadiene-Styrene block copolymer (SBS) is an innovative method of modifying asphalt mixture that has gained attention due to its convenience, low carbon footprint, and high efficiency. To understand ...
Compaction Quality Evaluation of Asphalt Pavement Based on Intelligent Compaction Technology
Publisher: ASCE
Abstract: Compaction quality (CQ) is one key index of asphalt pavement construction control. Compared with traditional control methods for asphalt pavement, intelligent compaction (IC) is an effective and new technology to control ...
