Predicting flexural-creep stiffness in bending beam rheometer (BBR) experiments using advanced super learner machine learning techniques

Research on Engineering Structures and Materials
BBR test is commonly used to assess the low-temperature performance grade (PG) of asphalt binders, with the flexural-creep stiffness being a critical parameter calculated through this test. However, it has notable limitations that demand attention.

Design Principles for Deployable Fibers Inspired by Hagfish Defense. [PDF]

Adv Sci (Weinh)
Hagfish slime deploys fibers from coiled skeins to form an ultra‐dilute, water‐trapping network. Inspired by this mechanism, design principles are established for synthetic skeins, fabricated with tightly coiled fibers that unravel under flow. These synthetic skeins demonstrate deployable fibrous networks, highlighting generalizable strategies for ...

Influence of warm mix additives on the low-temperature behavior of bitumen using the Bending Beam Rheometer (BBR) [PDF]

Construction and Building Materials, 2020
Abstract The mechanical and rheological characteristics of bitumen are crucial for the behavior and durability of the bituminous road layers. A bitumen susceptible to high temperatures can lead to plastic deformation of the bituminous layers, whereas a low temperature susceptible binder can lead to cracking of the bituminous layers.

Characterization of bituminous-sealants utilizing modified bending beam rheometer

Transportation Research Record: Journal of the Transportation Research Board, 2006
Early research showed that the current specification for the selection of crack sealants correlates poorly with field performance. To address this issue and help predict the low temperature properties of hot-poured bituminous sealants, a modified Bending Beam Rheometer (BBR) method is utilized. Eight sealants, with a wide range of rheological behaviors,

Evaluation of the Cohesive Properties of SBS-Modified Binders at Low Temperatures

Slovak Journal of Civil Engineering, 2021
The durability, fatigue resistance, and low-temperature behavior of asphalt layers are greatly affected by the properties of bitumen. Therefore, the composition of bitumen is frequently modified to improve the performance of asphalt mixtures.
