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 1st 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


11

be appropriate in certain cases. The costs are also based on pricing provided for non-bulk

orders.
