• Abstract:
  Monitoring of the environmental instrumentation installed under select pavement sections constructed ; by the Ohio Department of Transportation (ODOT) in 1995 on US 23 in Delaware County, Ohio was ; continued. The measurements made consisted of soil moisture, temperature and frost depth profiles. ; OSU constructed and installed tensiometers to directly measure the porewater pressures in the ; subsurface soils at seven locations at the DEL23 SHRP test road (four during original road construction ; and three more in 2002). Tensiometers were also installed and monitored at seven additional locations ; within the state. Those devices were monitored throughout the duration of the current project. ; A laboratory testing program was conducted to identify relationships between static soil properties ; and the design resilient modulus for compacted cohesive subgrade soils. Resilient modulus as well as ; classification and strength tests were performed on cohesive soil samples. The program to establish the ; relationships between dynamic soil behavior and static properties is described and a predictive tool ; developed through the use of artificial neural networks is presented.
