Use of FTIR Analysis to Verify Chemical Composition of Asphalt Binder

The primary objective of this project is to evaluate the chemical composition of modified binder and emulsion samples submitted by suppliers to the central office. This will be achieved through FTIR spectroscopy, a widely recognized analytical method in the asphalt industry. FTIR spectroscopy utilizes mid-infrared energy to analyze molecular structures and compositions by measuring the absorption of specific infrared light frequencies, offering a unique molecular fingerprint for identification and analysis. As the asphalt industry continues to evolve, suppliers are increasingly adopting advanced polymer additives to enhance binder formulations. It is essential for the state to verify the components used in these binder mixes to ensure quality and compliance.
