Static Data Tables

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:


Thermocouple

Long Term Strains

Long term strains changes in the pavement and at the joints are recorded with the static Carlson strain gages and with pavement joint gages. Data is stored under the following tables:
