Fields for table: INV_PMA

Field NameCodesData TypeUnitsTest ProtocolDescription
SHRP_ID

VARCHAR2(4)


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

NUMBER(4,3)


Bulk specific gravity of the fine aggregate.
MINERAL_FILLER_BULK_SPEC

NUMBER(4,3)


Mean bulk specific gravity for mineral filler.
AGGR_COMB_BULK_SPEC

NUMBER(4,3)


Mean bulk specific gravity of aggregate combination.
EFFECTIVE_SPEC_GRAVITY

NUMBER(4,3)


Aggregate combination effective specific gravity.
RECORD_STATUS

VARCHAR2(1)


A code indicating the general quality of the data.
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)

LAYER_NO

NUMBER(2)


Unique sequential number assigned to pavement layers, starting with layer 1 as the deepest layer (subgrade).
GEOL_CLASS_COARSE_AGGR
GEOL_CLASSNUMBER(2)


Code for geologic classification of coarse aggregate.
MINERAL_FILLER
MINERAL_FILLERNUMBER(1)


Code indicating the type of mineral filler.
MINERAL_FILLER_OTHER

VARCHAR2(40)


Type of mineral filler if other than those specified.
POLISH_VALUE

NUMBER(2)


Accelerated polish value of coarse aggregates in surface layer.
COARSE_AGGR_BULK_SPEC

NUMBER(4,3)


Bulk specific gravity of coarse aggregate.
