Ultrasonic-assisted preparation of SBS modified asphalt: Cavitation bubble numerical simulation and rheological properties

Ultrasonics Sonochemistry
SBS (styrene–butadiene–styrene block copolymer) is currently the most widely used asphalt modifier, and SBS modified asphalt is usually prepared by high-speed shearing.

Equivalent Subsurface Thermal Characteristics for Heterogeneous Surfaces

Geophysical Research Letters, Volume 53, Issue 15, 16 August 2026.
Abstract Land‐surface and atmospheric models often represent subgrid‐scale variability using a single set of effective properties. Estimating these equivalent properties is critical for predicting land‐atmosphere exchanges accurately, but challenging when materials with distinct radiative and thermal characteristics coexist, particularly in urban ...

Evolution and Influence Analysis of Skid Resistance Performance in Steel Slag Ultra‐Thin Wearing Course Based on XGBoost‐SHAP Framework

Applied Research, Volume 5, Issue 4, August 2026.
An XGBoost‐SHAP framework accurately predicted skid resistance evolution in steel slag ultra‐thin wearing courses under accelerated loading. Surface texture amplitude (Rz, Rq) and loading cycles dominated BPN variation, while 50% steel slag replacement provided a cost‐effective balance between anti‐skid durability and material use.

Effect of SBS Copolymer Molecular Structure on the Long‐Term Aging and Resilience of Asphalt Binders: A Multiscale Morphological Study

Macromolecular Materials and Engineering, Volume 311, Issue 8, August 2026.
Vinyl content governs the long‐term ageing resistance of SBS‐modified bitumen. Multiscale AFM, FM, SEM, and FTIR analyses show that low‐vinyl SBS copolymers (L‐SBS, B‐SBS) undergo pronounced bee‐phase growth, stiffening, and network fragmentation after PAV ageing, whereas high‐vinyl variants (HV‐SBS, DB‐SB) retain their morphology and chemistry ...
