Overview
Mandate
One outcome of the February 2009 Regional Mayors Forum in Nunavut was a petition to the
territory’s Ministry of Community and Government Services to investigate alternatives to the
use of calcium chloride for dust control on municipal roads.
The Ministry contacted ICURR to conduct a preliminary survey of alternative products, paying
particular attention to:




Costs including weights for shipping
Application process
Required equipment for application
Pros/con for environmental side effects
The Ministry also informed ICURR that Tembind, a lignin-based product, had already been
investigated locally and need not be considered in this survey.
Background
To place the options for consideration in context, it is important to consider the key benefits
for dust control or suppression:





Road maintenance costs can be lowered by reducing loss of aggregates
Road safety can be increased by improving visibility and road surface conditions
Dust-related health issues for humans can be minimized
Negative impacts of dust on wildlife and vegetation can be reduced
Damage to vehicles and equipment can be reduced
The decision on which dust control process is to be used must consider several important
questions:







Is the product environmentally responsible? Does it meet regulatory standards?
Is special equipment required to apply the product?
Are there safety issues for employees and/or contractors in handling the product?
Will there be any need for special storage and warehousing?
How effective is the product in achieving the desired outcome?
What is the required frequency of application? How durable is the product?
Cost?
Before even embarking upon a dust suppression strategy, the road authority should determine
if other elements of road performance have been incorporated into the assessment. Road
design and construction, including crowns, shoulders and drainage should be examined. Are
appropriate surface materials being used? Have reduced speed limits been considered? Is
paving an option?
2016 Update
The purpose of the update was to identify whether the companies identified in 2009 were still
operational and whether they carried the products that were identified in 2009 or if they had
new products that were developed since 2009 for dust suppression. In addition to conducting
an update on the previously identified companies and their products a search was conducted
into other companies and their dust suppression products which were not considered or may
have not existed in 2009.
Although there have been a few distribution company name changes, eights of the nine
products examined in 2009, are still available for distribution in 2016. These companies were
contacted to obtain an update on their current costs and to determine if there have been any
changes in the products that were identified in 2009. In addition three new companies and
four products were added to the companies identified in 2009 and updated in 2016.
One company which was contacted for an update refused to provide price updates due to their
policy of not providing quotes for non-account holders therefore the 2009 cost estimate was
not able to be updated.

Product Descriptions
The categories of products for dust suppression include:





Hygroscopics (magnesium chloride, calcium chloride, etc)
Lignin derivatives (e.g. Tembec’s Tembind or TDS)
Bitumens, tars and resins
Vegetable oils (canola, soybean, linseed etc)
Synthetic polymer emulsions
Since the chlorides currently in use in Nunavut have been determined to be undesirable, and
a lignan product has already been tested, ICURR did not include any products based on these
compounds in this survey. Bunker C oil was to be considered but has been omitted from this
report due to its negative environmental impacts (Yukon) and the fact that changes to
petroleum refining processes have rendered the product scarce and relatively expensive
(interview with Frank Hall, OGRA).
In most cases, any dust suppressant will be affected to a certain extent by the conditions in
which it is being applied and under which it is expected to perform. The local soil (percentage
of sand, glacial till, clay etc), the drainage conditions, the application process and the
application rates all play into the product’s performance. Similarly, traffic type and density
need to be taken into account. The number of vehicles per day and the type of vehicles
(percentage which are automobiles, light-duty trucks, heavy equipment, ATVs etc) will both
need to be assessed against product features in order to determine the best choice for the
particular situation.
Given that most product testing has been conducted in southern Canada and the United
States, product selection for use in far northern locales should probably be preceded by testing
under local conditions and on tundra soils. It is important to stress that the manufacturer’s
recommended application rates need to be followed to guarantee results.
There are many companies in North America selling dust suppressant products for roads and
this report does not attempt to be comprehensive or recommend one product over another.
The sampling attempts to provide an array of alternative products representing different
product categories and including both Canadian and American suppliers capable of delivering
in the volumes required.

Product Application
Application of dust suppressant products can be either topical or worked into the surface via
grading or scarification. Some products are applied as supplied and others require additional
handling (e.g. mixing, pumping, heating, compacting etc). Products come in a variety of forms
including liquids, emulsions, powders etc. Curing times are often dependent upon climate
conditions at the time of application and can also vary significantly from product to product.
The durability of dust suppressants depends upon the type of product used, its application,
the amount of rainfall, the temperature and the amount of traffic. Some product durability is
enhanced with each subsequent application.

Product Shipping and Cost
Obviously, in shipping these products any great distance, the shipping costs can be the single
largest expense. Product pricing in almost all cases will vary depending upon the quantities
ordered, and shipping costs will vary based on the weights of the product and the distances
to be shipped.
The products are generally available in bags (50 to 55 pounds) or totes if they are in powdered
formats and 450 pound drums or 2000 plus pound totes if they are liquid. Bulk shipments are
available for most products will result in better pricing for both product and shipping costs.
Most product manufacturers indicate that surface condition is a factor in product efficiency
and surface preparation costs will only be known on a case by case basis. This can range from
no surface preparation required to extensive grading, scarification and drainage work. Clearly,
the more preparation required prior to application will have an impact on cost.
Application rates vary from product to product. Even with the same product, suppliers often
specify a range of application rates depending upon road and climate conditions.
Application equipment costs in many cases will be no greater than current costs where typical
water trucks with sprayer attachments are used. However, in some cases, products will
necessitate the addition of agitators or pumps which will need to be factored in to cost
estimates.
The durability of the product is another factor to be considered when evaluating cost.
Durability claims vary widely from product to product and those claims will need to be
evaluated on a case by case basis. Some products would need multiple applications per season
while others claim to need only one. Most products must be reapplied after reworking the
surface for maintenance but at least one claims to continue to be effective after reworking.
After the initial application, some products are applied at the same rate for all subsequent
applications while others can be applied at significantly reduced rates on subsequent
applications (as little as 30% of the 1 st application). All of these elements can have a dramatic
effect on the cost.
In comparing costs, the relative environmental impacts, while difficult to quantify, should be
factored in. Also, when compared to chloride based products, all of the products surveyed for
this report do not have the corrosive qualities on machines and equipment normally
associated with chlorides.
Finally, product handling and storage is different from product to product. Emulsions require
careful handling and cleaning of equipment, some products work best when applied in warm
weather and others claim to be easily applied in below freezing weather. This may result in
incremental costs or savings for the road authority.
The cost estimates in the table that follows are based on application rates that are either the
recommended rate or the highest rate for maximum results and durability. Lower rates might
10
be appropriate in certain cases. The costs are also based on pricing provided for non-bulk
orders.
