**************************************************************************
NOTE: Paragraphs Measurement and Payment will be
deleted if the work covered by this section is
included in one lump-sum contract price. Lump-sum
contracts will not be used when the job exceeds 500
metric tons (tons). For lump-sum contracts, the
Contractor may be required to perform all aggregate
quality testing and developing the job mix formula.

Measurement
1.2.1.1
Porous Friction Course
Porous friction course (PFC) tonnage paid for will be the number of metric
tons 2000 pound tons of bituminous mixture used in the accepted work.
Bituminous mixture shall be weighed after mixing, and no deduction will be
made for weight of bituminous materials incorporated in the mixture.
1.2.1.2
Correction Factor for Aggregates Used
Quantities of paving mixtures called for are based on aggregates having a
specific gravity of 2.70, as determined in accordance with the Apparent
Specific Gravity paragraphs in ASTM C 127 and ASTM C 128. Correction in
tonnage of PFC mixtures shall be made to compensate for the difference in
tonnage of the mixtures used in the project, when specific gravities of
