LTPP TABLE NAVIGATOR: Field View


Fields for table: MON_DEFL_LOC_INFO

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.
CONFIGURATION_NO

NUMBER(6)


Sequential index number that represents a unique set of instrument configuration and calibration settings. The index is incremented each time a change is made to any of the FWD configuration settings.
CRACK_JOINT_OPEN_WIDTH

NUMBER(2)
mm

Width of opening through the pavement at the cracks and joints across which load transfer deflection tests were performed. Values 25-mm or greater are set to 25.
PVMT_SURF_TEMP

NUMBER(4,1)
deg C

Pavement surface temperature measured by the FWD automatic temperature sensor.
AIR_TEMP_TEST

NUMBER(4,1)
deg C

Air temperature measured inside the FWD tower enclosure at the start of deflection test sequence at this point location.
COMMENTS_1

VARCHAR2(80)


Field comments from FWD operator concerning pavement features and other conditions which may influence deflection measurements at this location.
COMMENTS_2

VARCHAR2(80)


Continuation of field comments from FWD operator concerning pavement features and other conditions which may influence deflection measurements at this location.
LATITUDE

NUMBER(8,6)
deg

Latitude of the test point as measured by the unit's GPS
LONGITUDE

NUMBER(9,6)
deg

Longitude of the test point as measured by the unit's GPS
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 test was performed.
TEST_TIME

VARCHAR2(4)
hhmm

Time deflection test sequence at this location was begun.
DEFL_UNIT_ID

VARCHAR2(12)


Serial number or other unique ID for the deflection device.
POINT_LOC

NUMBER(4,1)
m

Distance from the start of the section to where the test was performed.
LANE_NO
LANE_SPECVARCHAR2(2)


Code indicating the lane or position where the deflection test was performed.
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.
