[0003] The sample preparation of polymer-modified asphalt will affect the observation results. The temperature and thickness of the film are the main factors affecting the observation of the dispersion state of polymer-modified asphalt. According to the current research, a polymer-modified asphalt can be used to Measurable film thickness uniform temperature control film production device and method to realize the preparation of standard samples; In addition, in fluorescence microscopy, image acquisition and image processing methods are different, and there is no unified standard

Even for the same method, the steps used by different researchers are quite different, which leads to huge differences in the morphological parameters of the polymer phase obtained after treatment, which affects the evaluation of the effect of polymer modified asphalt
