聚合物改性沥青显微结构及量化研究

Microscopic and Quantitative Analysis of Polymer Modified Asphalt

荧光显微照相技术不会破坏聚合物相在沥青中的形态 ,是评价改性沥青机理的有效手段。本文介绍用荧光显微照相观测到聚合物相在沥青中真实的相态结构及如何利用改进的方法获得大量重现性很好的显微图像 ,本文还对目前改性沥青显微结构的研究现状及存在的问题进行了评价与分析 ,并提出改进的方法 ,配备了数字化处理所需的硬件设备及功能完善的图像处理软件 ,可以对聚合物改性沥青的显微结构进行量化分析。

Fluorescence optical microscopy will not affect the polymer phase microstructure in asphalt and it is an effective method to study the mechanism of polymer?modified asphalt(PMA).The way to observe the real polymer phase structure by Fluorescence optical microscopy is introduced and a modified way was given to obtain a mass of representative micro image.Then the statement about the microstructure analysis of PMA by Fluorescence optical microscopy and the method of microstructure analysis of PMA are given.According to the method,equipped with relevant hardware and image manipulation software,microstructure of PMA can be quantitatively analyzed.
