616.01 Description. This work consists of
applying water or dust palliative for the alleviation or prevention of dust
nuisance originating from earthwork construction operations from within the
project construction limits.
616.02 Construction Requirements. Perform
dust control operations at the time and location and in the amount ordered by
the Engineer. Maintain control of the application of water or dust
palliative at all times to minimize dust but not to create saturated soil
conditions. The Engineer will determine whether water or dust palliative
is to be used to alleviate or prevent dust nuisance, and the amounts of each
material to be used. Do not apply calcium chloride to areas that will be
subsequently seeded or sodded.
Furnish
and apply water used for dust control by means of tanks equipped with suitable
sprinkling devices.
Use
dust palliative consisting of 712.02 calcium chloride or a
brine solution containing a minimum of 30 percent by weight of calcium chloride.
Spread the calcium chloride uniformly over the surface.
616.03 Method of Measurement. The
Department will measure Water by the number of M gallons or 1000 gallon units
(cubic meters) applied and measured either in tanks, tank wagons, or trucks of
predetermined capacity; or by means of meters of a type and furnished and
installed by the Contractor at no expense to the Department; or determined by
weight conversion.
The
Department will measure Calcium Chloride by the number of tons (metric tons) by
weight measurement, furnished and applied. When brine is used, the
Department will determine the weight of calcium chloride by multiplying the
number of gallons (cubic meters) by the factor 0.0024 (0.575).
616.04 Basis of Payment. The
