RISMacro–Micro Testing and Molecular Simulation on the Aging Mechanism and Behavior of SBS-Modified High Viscosity Asphalt
Publisher: ASCE
Abstract: In this paper, the thermal oxygen aging test was conducted on the styrene-butadiene-styrene block copolymer (SBS) type high viscosity modifier (HVM), and the appearance, solubility, functional groups, and molecular weight ...
Permittivity Heterogeneity Influence of Multiphase Pavement Materials on Ground-Penetrating Radar Detection Results: A Study Based on Probability Distribution
Publisher: American Society of Civil Engineers
Abstract: For ground-penetrating radar (GPR) detection, multiphase heterogeneous pavement models were built and on-site detections were conducted. The statistic distribution rules of relative permittivity in pavement materials ...
Evaluation of Reclaimed Asphalt Pavement Binder Rejuvenating Behavior during Hot In-Place Recycling
Publisher: ASCE
Abstract: In this paper, a micro-macro evaluation method of rejuvenator diffusion extent into aged asphalt in hot in-place recycling was put forward considering the cooling process of the recycled layer after paving. The material ...
