Abstract:

Mineral aggregates were found to exhibit unique spectral fingerprints or spectral patterns, when subjected to a high irradiance induced by focusing a high powered laser onto very tiny spot on a target aggregate material. These spectral patterns were successfully correlated with engineering material properties of the targeted material. Using multivariate determinant models, the acid insoluble residue content, the presence of D-cracking susceptibility and alkali-silica reactivity were accurately predicted on aggregates supplied by New York, Kansas and Texas Departments of Transportation, respectively. The subject technology has the potential to rapidly classify material properties providing material suppliers and transportation agencies with a real time, recording tool for monitoring materials used in highway construction.
