17. Specification Reminders
A. Specification Section 337 “Special Construction Requirements”-“Compaction of FC-5”
1) Provide two, static steel-wheeled rollers, with an effective compactive weight in the range of 135
to 200 PLI [2.4 to 3.6 kg/mm], determined as follows:
PLI = Total Weight of Roller (pounds) / Total Width of Drums (inches)
(Any variation of this equipment requirement must be approved by the Engineer.) Establish an
appropriate rolling pattern for the pavement in order to effectively seat the mixture without
crushing the aggregate. In the event that the roller begins to crush the aggregate, reduce the
number of coverages or the PLI of the rollers. If the rollers continue to crush the aggregate, use a
tandem steel-wheel roller weighing not more than 135 lb/in (PLI) [2.4 kg/mm] of drum width.
B. Specification Section 334 “Acceptance of the Mixture”-“Option 1 Mixture Acceptance”-“Acceptance
Exceptions”
