多维数多尺度纳米材料改性沥青的微观机理
Microscopic Mechanismvof Modified Asphalt by Multi-Dimensional and Multi-Scale Nanomaterial
摘要
Abstract
The nano-material with organobentonite,nano-SiO2and SBS at different dimensions and scales was used to modify a base asphalt material.The properties of asphalt modified with the nanomaterial were investigated by scanning electron microscopy,Fourier transform infrared spectroscopy,gel chromatography and differential scanning calorimetry,respectively.These properties investigated involved the microscopic structure feature,formula weight and absorbed heat during the change state of aggregation.The modification mechanism was proposed from the microscopic point of view.Compared to the macroscopic properties,the results reflected the consistency of the micro-modification mechanism and the pavement performance at a macroscopic level.关键词
