CC7 North Instrumentation Plan
Over 150 sensors of various types were installed in the test pavement. Dynamic sensors consisted of H-bar Asphalt Strain Gages (ASG) at the bottom of the P-401 asphalt HMA, Fiber Optic Strain Plate (FOSP) in test items LFC1-N to LFS5-N to measure transverse and vertical strains at the top and transverse stains at the bottom within the P-401 asphalt HMA layer, Multi-Depth Deflectometers (MDD), and Pressure Cells (PC) on the top of the clay subgrade. Static sensors included moisture sensors (MS), specific heat sensors, thermocouples (T), and air temperature/relative humidity sensors.
12 Multi-depth deflectometers (MDD)
12 Pressure cells
42 Asphalt strain gages
4 Fiber optic strain plates
4 Fiber optic strain gages
