Abstract
Laser scanning of transportation aggregate materials provided a means to identify aggregate types, sources, and quality in near-real time. A multi-state project led by the Kansas Department of Transportation (KDOT) and facilitated by Chesner Engineering (Coeymans, New York) used laser ablation breakdown spectroscopy (LIBS) to determine whether the technique could be used to predict durability (D)-cracking aggregate susceptibility and whether LIBS could be evaluated to ensure that the source materials were all derived from approved materials. This poster focuses only on the Kansas portion of the project. Six years of study indicates that LIBS may be used as a quality control tool to identify or fingerprint targeted aggregates materials related to D-cracking susceptibilities 80% to 100% of the time if the partial least square regression (PLSR) source models is used.
