A FIELD VERIFICATION OF VESYS IIIA STRUCTURAL SUBSYSTEM. SIXTH INTERNATIONAL CONFERENCE, STRUCTURAL DESIGN OF ASPHALT PAVEMENTS, VOLUME I, PROCEEDINGS, UNIVERSITY OF MICHIGAN, JULY 13-17, 1987, ANN ARBOR, MICHIGAN

Presented in this paper are the results of the field verification of VESYS IIIA structural subsystem. Five pavement sections in different geographical locations of North Carolina were selected for this study. The layer materials from these pavement sections were characterized in the laboratory by subjecting specimens of the given materials to a series of creep and dynamic load tests under environmental conditions representative of those experienced in the field. The characterization of asphaltic mixtures was done using the direct compression test and the diametral tension test. Based on the input of the mechanical properties of the layer materials, the actual traffic volume, and the local environmental conditions, the performance of the pavement sections was predicted using the VESYS IIIA structural subsystem. The predicted performance parameters (rutting, cracking, and present serviceability index) were compared with the actual measured performance parameters. The predicted performance using the mechanical properties, as determined by the direct compression test, matched quite will with the actually measured performance. On the other hand, the input of the mechanical properties, as determined by diametral tension test, almost always overestimated the performance of the pavements.
