Fields for table: MON_DEFL_TEMP_VALUES

Field NameCodesData TypeUnitsTest ProtocolDescription
STATE_CODE
STATE_PROVINCENUMBER(2)


Numerical code for state or province. U.S. codes are consistent with Federal Information Processing Standards.
LAYER_TEMPERATURE_3

NUMBER(4,1)
deg C

Measured subsurface layer temperature at depth stored in MON_DEFL_TEMP_DEPTHS.LAYER_TEMP_DEPTH_3 with matching LOCATION_NO.
LAYER_TEMPERATURE_4

NUMBER(4,1)
deg C

Measured subsurface layer temperature at depth stored in MON_DEFL_TEMP_DEPTHS.LAYER_TEMP_DEPTH_4 with matching LOCATION_NO.
LAYER_TEMPERATURE_5

NUMBER(4,1)
deg C

Measured subsurface layer temperature at depth stored in MON_DEFL_TEMP_DEPTHS.LAYER_TEMP_DEPTH_5 with matching LOCATION_NO.
WEATHER_CONDITION

VARCHAR2(15)


Weather related comments, and any other comments necessary to explain unusual temperature readings.
SURFACE_TEMPERATURE

NUMBER(3,1)
deg C

Pavement surface temperature as measured with infrared thermometer.
SHRP_ID

VARCHAR2(4)


Test section identification number assigned by LTPP program. Must be combined with STATE_CODE to be unique.
TEST_DATE

DATE


Date the temperature reading was taken.
POINT_LOC

NUMBER(4,1)
m

Distance from the start of the section to where the test was performed.
TIME_LAYER_TEMP

VARCHAR2(4)
hhmm

Start time for layer temperature measurement sequence.
RECORD_STATUS

VARCHAR2(1)


A code indicating the general quality of the data.
CONSTRUCTION_NO

NUMBER(2)


Event number used to relate changes in pavement structure with other time dependent data elements. This field is set to 1 when a test section is initially accepted into LTPP and is incremented with each change to the layer structure.
LAYER_TEMPERATURE_1

NUMBER(4,1)
deg C

Measured subsurface layer temperature at depth stored in MON_DEFL_TEMP_DEPTHS.LAYER_TEMP_DEPTH_1 with matching LOCATION_NO.
LAYER_TEMPERATURE_2

NUMBER(4,1)
deg C

Measured subsurface layer temperature at depth stored in MON_DEFL_TEMP_DEPTHS.LAYER_TEMP_DEPTH_2 with matching LOCATION_NO.
