CC8 Instrumentation Plan

Static and dynamic sensors were installed in different pavement layers to monitor responses to traffic and environmental loads. Static sensors included Thermocouples in PCC slab and Moisture Sensor in subgrade and P-154M subbase. These static sensors recorded temperature and moisture on an hourly basis. Dynamic sensors included embedded strain gauge (EG), eddy current sensor (ECS), Potentiometer (POT), pressure cell (PC) and Resistance Gauge (RG). The dynamic sensors measured pavement responses under the load and were triggered by vehicle passes. Moisture sensors (placed in the P-152M and P-154M layers) and pressure cells (placed in the P-152M layer) were the only sensors placed in the subgrade and subbase layers. Instrumentation within P-501MR was selected and installed to monitor vertical movement of the test slabs and measure strain responses at the top and bottom of the slab. The gauge selection was based on reliability, accuracy, and ease of handling at the construction site. The types and quantity of each gauge in addition to the sections they were placed in are presented in the table below.

CC8 Phase 1 Overload & Phase 2 Overlay Test

The images below displays the instrumentation plan for both Phase 1 and Phase 2. Sensors denoted with a 'O-I' in the name specify Phase 1 Overload. Sensors denoted with O-II' in the name specify Phase 2 Overlay.

 

For a table of sensor coordinates for the different phases reference Sheet 14 of 34 of the CC8 As-Built Drawings linked above.
