T/JSJTQX 05-2019 Infrared Spectroscopy Identification of Asphalt and Test Procedure for SBS Additive Content
T/JSJTQX 05-2019
Basic Information
Scope
Scope: This standard specifies the requirements for instrumentation, methods and procedures, allowable errors, and test reports for infrared spectroscopy identification of asphalt and SBS content testing. This standard is applicable to the evaluation of asphalt quality and determination of SBS content in modified asphalt by infrared spectroscopy. Main technical content: This technology mainly adopts Fourier infrared spectroscopy to conduct qualitative and quantitative analysis of asphalt quality from the perspective of asphalt chemical composition. The main technical content includes instrumentation requirements, sampling and sample preparation methods, test operation steps, asphalt similarity detection, standard curve establishment, and SBS content detection in modified asphalt. Compared with traditional physical detection methods mainly based on mechanical properties, this technology can more effectively identify asphalt quality, which is of great practical significance and promotion value for further improving the quality of road engineering construction in our province.
