DB32/T 4340-2022 Technical code for infrared spectrum identification of asphalt similarity and determination of SBS content
Abstract
This document specifies the requirements for the instruments and materials used in the infrared spectroscopy test to identify the similarity of asphalt and the SBS content, as well as the requirements for identifying the similarity of asphalt, testing the SBS content, data processing and result determination, and recording and reporting the test results. This document is applicable to the use of Fourier transform infrared spectroscopy to identify the similarity of asphalt and determine the SBS content in modified asphalt.
