During the construction of the AASHO Road Test facility, and in the subsequent restoration of the facility for service as a part of Interstate 80, electronic scales were installed in the pavements to measure the dynamic weights of axles of vehicles traveling at normal speeds in the regular traffic stream. Calibration tests produced inconsistent results, especially at higher speeds, and showed no simple relationship to exist between dynamic and static loadings. Platform vibration caused serious interference in the oscillograph recordings of axle loads. Several modifications that were made in the system to overcome the interference were unsuccessful. Insurmountable maintenance problems resulting from poor resistance of the scale system to the normal environmental conditions of the site brought about a termination of the study. (Author)
