Automated Laser Spectrographic Pattern Matching for Aggregate Identification

TRB’s National Cooperative Highway Research Program (NCHRP) Innovations Deserving Exploratory Analysis (IDEA) Final Report for NCHRP-IDEA Project 150: Automated Laser Spectrographic Pattern Matching for Aggregate Identification evaluates the feasibility of using laser-induced breakdown spectroscopy as a quality control tool to scan in real-time aggregates used in highway construction applications.
