Embodiment Construction
[0035] In order to facilitate the understanding of the present invention, the embodiments of the present invention will be described below in conjunction with the accompanying drawings. Those skilled in the art should understand that the following description is only for the convenience of explaining the present invention, not as a specific limitation on its scope.
[0036] In the present invention, a Raman spectrometer is used to detect the content of the SBS modifier. The Raman spectrometer is an instrument that can normally measure asphalt samples. In the present invention, the Horiba JY HR800 Raman spectrometer is preferably used. Since the Raman signal is much smaller than the background fluorescence, in order to amplify the Raman signal and eliminate the influence of the background fluorescence, the test sample is placed in the artificial metal micro-nano structure in the present invention, which can realize the Raman Signal enhancement. In the artificial metal micro-nano...
