Opis

Proceedings of sessions at the Third National Conference of the Geo-Institute, held in Urbana-Champaign, Illinois, June 13-17, 1999. Sponsored by the Pavements Committee of the Geo-Institute. This Geotechnical Special Publication contains five papers focusing on field and laboratory characterization of transportation geo-materials. Characterization makes use of various nondestructive testing techniques (falling weight deflecometer, spectral analysis of surface waves, ground penetrating radar, seismic pavement analyzer, Humbold stiffness gauge) and cone penetration testing for field characterization, application of a new Tube Suction test method for characterizing durability of pavement foundation core samples, and laboratory stress path testing of granular materials under dynamic confinement conditions using a new advanced triaxial test device. Topics include evaluation of in situ resilient modulus testing techniques, evaluation of geogrid-reinforced granular base, durability of recycled and stabilized pavement materials, characterization of track substructure performance, and unbound granular material characterization from stress path loading tests.
