Assessment of Stress and Strain Instrumentation in Accelerated-Pavement Testing

Pavement sensors are widely used in accelerated pavement facilities and in full-scale instrumented test sections to allow for validation of analytical models and to assess the effects of different control variables such as temperature and tire configurations. In spite of their essential role in instrumented facilities, only a limited number of studies have been conducted to assess the accuracy, repeatability, and survivability of pavement sensors. The primary objective of this study was to determine the survivability and repeatability of stress and strain measurements. In addition, seasonal variation and the use of sensor technology to monitor the evolution of pavement damage at the Louisiana Accelerated Load Facility (ALF) were investigated. Pavement performance and responses were analyzed over a 40-month period in which 625,000 cycles were applied on the test section. Results of this analysis indicated that repeatability and survivability of strain and stress sensors were acceptable. In addition, pavement responses were strongly influenced by the temperature during testing.
