Static Data Tables
Data from the static (hourly) sensors is stored under similar table names.
Temperature and Moisture Content
Temperature and moisture content values measured across the pavement structure are stored under the Thermocouple Thermocouple and the TDR Moisture selections. In addition raw velocity measurements from the Time Domain Reflectometry rods are provided under the TDR Velocity selection. These can be used by anyone who wishes to compute moisture content using a calibration equation than the one selected in this project. Data is stored under the following tables:
