• Abstract:
  The goal of this project was to characterize the relative performance and changes in microstructural and engineering properties for various types of coarse aggregates subjected to weathering as well as real and simulated traffic loads typical of granular surfaces and shoulders of Iowa roads. Through an extensive program of geotechnical laboratory tests, image analysis, geological laboratory tests, and analysis of data from prior projects, the deterioration of both fresh quarry samples and field test section samples was analyzed and compared.
