LTPP TABLE NAVIGATOR: Field View


Fields for table: MON_DEFL_DROP_DATA

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.
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.
DROP_HEIGHT
DROP_HEIGHTVARCHAR2(1)


Integer code for the height from which the weight was dropped.
DROP_LOAD

NUMBER(6)
kPa

Peak drop load (plate pressure).
HISTORY_STORED
Y_NVARCHAR2(1)


Code indicating if the history data were stored for this drop.
PEAK_DEFL_1

NUMBER(4)
microns

Peak deflection at sensor 1.
PEAK_DEFL_2

NUMBER(4)
microns

Peak deflection at sensor 2
PEAK_DEFL_3

NUMBER(4)
microns

Peak deflection at sensor 3.
PEAK_DEFL_4

NUMBER(4)
microns

Peak deflection at sensor 4.
PEAK_DEFL_5

NUMBER(4)
microns

Peak deflection at sensor 5.
PEAK_DEFL_6

NUMBER(4)
microns

Peak deflection at sensor 6.
SHRP_ID

VARCHAR2(4)


Test section identification number assigned by LTPP program. Must be combined with STATE_CODE to be unique.
PEAK_DEFL_7

NUMBER(4)
