Utilization of Laser Induced Breakdown Spectroscopy (LIBS) for Real-Time Testing and Quality Control Monitoring of Aggregate Materials used in Highway Construction

The overall objective of this project is to upgrade quality control/quality assurance (QC/QA) in the highway construction industry by developing a real-time laser scanning system to rapidly classify aggregates used in highway construction. The intent is to employ this classification process to (1) Quantify specific engineering properties (e.g., specific gravity, acid insoluble residue, Microdeval loss, etc.); (2) Assess whether an aggregate source will pass or fail a defined engineering property test; (3) Identify and/or quantify the presence of deleterious materials (e.g., reactive aggregates, cherts, etc.); (4) Determine whether aggregate composition or quality is changing during production, and (5) Determine the source material or sources of blended production materials. An aggregate laser scanning system has the potential to be employed in private and government material testing laboratories, where laser scanning of aggregate samples can be undertaken, providing multiple engineering parametric results in near real time.
