Operations and Maintenance Manual: Pavement Test Track Instrumentation System

Description: Several pieces of electronic hardware, obtained through previous test efforts have been assembled for laboratory and field use. The equipment consists of two instrument racks. The first contains five Bison inductance type soil strain gauge instruments and the associated phase and amplitude controls and solid state switching hardware for switching these controls between sixteen measurement test sections. 

The second rack contains switch hardware for switching the actual input leads for the individual inductance coils associated with the sixteen test section. It also contains the necessary data acquisition and analysis hardware.
