原始语种摘要: Abstract(#br)Saving mixing energy by using escaping and bursting bubbles during the production process of nanomaterial-modified water-foamed asphalt is a novel preparation idea, which can be taken as one type of cleaner physical warm-mix asphalt technology. The objective of this study is to assess the dispersal of nano hydrated lime (NHL) particles in the asphalt using a scanning electron microscopy (SEM) test, and to evaluate the physical properties of NHL modified water-foamed asphalt (NMFA). In this study, the NHL and sodium dodecylbenzene sulfonate (C 12 H 25 C 6 H 4 SO 3 Na) were added to the water to form suspensions, and the suspensions were mixed with asphalt to form NMFA. The X-ray diffraction (XRD) test was used in order to understand the NMFA’s microstructure and dispersal of...
