RISAFM-Based Approach to Study Blending between RAP and Virgin Asphalt Binders
Publisher: American Society of Civil Engineers
Abstract: In this paper, atomic force microscopy (AFM) is used to evaluate micromechanical properties of the interfacial blending zone between reclaimed asphalt pavement (RAP) and virgin asphalt binders. Three virgin asphalt binders ...
Nanoscale and Macroscale Characterization of the Influence of RAP and RAS on Cracking Resistance of Asphalt Mixes
Publisher: American Society of Civil Engineers
Abstract: This paper summarizes the results of laboratory tests that were performed to characterize the blending of recycled asphalt binders [recycled asphalt shingles (RAS) and reclaimed asphalt pavement (RAP) binders] and virgin ...
Micromechanical and Chemical Characterization of Foamed Warm-Mix Asphalt Aging
Publisher: American Society of Civil Engineers
Abstract: This study evaluates the effects of aging on the micromechanical and chemical properties of foamed warm-mix asphalt (WMA) and hot-mix asphalt (HMA) materials. Two asphalt binders were considered. Atomic force microscopy ...
Revealing Three-Dimensional Morphology in Nanoporous Gold Using Three-Dimensional X-Ray Fresnel Coherent Diffractive Imaging Tomography
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Nanoporous metals fabricated by dealloying have a unique bi-continuous, sponge-like porous structure with ultra-high surface area. The unique properties of these materials, especially nanoporous gold, have numerous potential ...
