The short answer
Road dust abatement means keeping dust down on unpaved roads, lots and yards, usually by applying a dust palliative. That's a product that holds the fine particles in the surface so tires and wind don't lift them. It has nothing to do with asbestos or indoor abatement. Treatments wear off, so the work gets repeated, usually every year.

What road dust abatement means
Road dust abatement is cutting down the dust that comes off unpaved roads, lots and yards. The USDA Forest Service's guide on the subject starts with why it matters. Dust from unpaved roads "is not only a nuisance but creates a safety hazard by reducing driver visibility."1 The same guide says it adds wear and tear on vehicles.
It costs the road, too. The guide explains that the fine particles help hold an unpaved surface together, and when they blow away the surface ravels and maintenance costs go up.1 So abatement is about keeping your road in shape as much as it's about the air.
Road dust abatement vs other abatement work
Search for dust abatement and you'll turn up indoor cleanup and asbestos outfits. This page is about something else, the outdoor dust off gravel and dirt surfaces, treated with a product sprayed on the ground. If your question is about a building, I'm not the guy you want.
How a dust palliative works
The products are called dust palliatives or dust suppressants. The Forest Service guide says they work in one of three ways. They clump the fine particles together, bind the surface particles to each other, or pack the road surface tighter.1 Either way, in the guide's words, "they reduce the ability of the surface particles to be lifted and suspended by vehicle tires or wind."1
The kinds of products
The Forest Service guide sorts dust palliatives into seven groups. They are water, water-absorbing products, petroleum-based products, organic non-petroleum products, electrochemical products, polymer products and clay additives. It says it "does not endorse any particular product."1
Lignin sulfonate, the one product we apply, sits in the organic non-petroleum group. The FHWA handbook files it there too.3 When we do a road, we pre-wet it with water, then spray the lignin, and you can drive on it right away. How the groups compare, from federal road guides, is in dust control products compared.
It isn't permanent
Abatement is a job you come back to. The Forest Service guide says dust suppressants "are not a permanent solution and will require further applications as the effectiveness of the product decreases with time."1 The FHWA gravel roads manual agrees that virtually every method of dust control needs treating again each year.2 The good news, per the Forest Service, is that the later applications may be lighter than the first one.1 Ours is built to last the season, and then it's time again the next summer.
The permanent fix is a sealed surface. The guide says paving or a bituminous surface treatment ends the dust problem, and it notes that on low-volume Forest Service roads the traffic doesn't justify the cost.1
Who orders it
- Counties and agencies. Jackson County Roads applies its own surface stabilization treatments on selected sections of county-maintained gravel roads, separate from the dust program residents use.4
- Residents on county roads. In Jackson County, people who live along county-maintained gravel roads can arrange dust abatement with an applicator through the county's program.4
- Owners and businesses. Private roads, driveways, lots and yards are the owner's to arrange. Our own customers run from everyday people to businesses, truck lots and government contracts.
In Jackson County
Jackson County Roads runs a dust abatement program for county-maintained gravel roads. Applicators working in the county right-of-way need a permit from Jackson County Roads, and products "must be pre-approved by Jackson County Roads to meet minimum safety standards."4 The county may also grade the road first at no cost to the applicator or residents. Lignin sulfonate is one of the examples of approved products the county gives.4 The details are in the Jackson County program. To check how it applies to your road, call Jackson County Roads at (541) 774-8184.

Questions people ask
What is dust abatement on a road?
Keeping dust down on an unpaved road, lot or yard, usually by applying a dust palliative. That's a product that holds the fine particles in the surface so tires and wind don't lift them. It's outdoor road work, and it has nothing to do with indoor or asbestos abatement.
Is dust abatement the same as dust control?
For roads, yes, it's the same work. The USDA Forest Service guide talks about a "dust abatement program," and the FHWA gravel roads manual calls it dust control.
What is a dust palliative?
A product applied to an unpaved surface to cut down dust. The Forest Service guide says dust suppressants work by agglomerating the fine particles, binding the surface particles together, or increasing the density of the road surface, and that they aren't a permanent fix.
Does Jackson County pay for dust abatement on my road?
Not for the treatment itself. On county-maintained gravel roads, residents arrange it with an applicator, the applicator gets a permit from Jackson County Roads, and the county may grade the road first at no cost. Jackson County applies its own surface stabilization treatments on selected road sections, and that's a separate thing. To check how it works on your road, call Jackson County Roads at (541) 774-8184, or call us.
