Oh, Happy Day!

It’s a miracle!  The “pray for spray”  has been answered!  The dust bowl days are over (well, not really, but a girl can dream)!

Today, east 120th Street received calcium chloride dust control treatment from stem to stern.  I was able to walk out and get the mail without my gas mask!  Imagine!

Seriously, the entire neighborhood sends out our sincerest “thanks” to Stillwater Township Chair David Johnson and May Township Chair Bill Voedisch for their joint efforts to get us this blessed relief from what was turning into a genuine respiratory health hazard. 

This wonderful product actually has  a myriad of benefits to cow paths across the country.  Read on . . . 

Dust Control with Calcium Chloride
Billowing clouds of dust are recognized by the general public as a nuisance and sometimes even as a hazard. Yet every highway superintendent knows that the tiny particles, or “fines,” serve a vital function in the roadway surface if they can be held there.

So long as they remain in the surface, the fine particles stabilize the unpaved roadway by acting as a binding agent for the coarser aggregates. But when those fines are lost in the air, the road surface begins to loosen, and traffic starts scattering the expensive roadway aggregate into ditches and culverts. If unchecked, this continuous deterioration of the roadway surface will result in the need for extensive road rebuilding and attendant high costs.

A proper application of calcium chloride helps stop the deterioration before it begins. When applied as a dust control agent, calcium chloride consolidates and stabilizes the roadway to provide a clean, smooth-riding surface.

Benefits of Calcium Chloride
Calcium chloride has a long history of use as a dust control agent for unpaved roadways, parking lots and other unpaved surfaces, and its use in this application is continually growing. The consistent increase in acceptance of calcium chloride can be attributed to the combination of the following benefits:

1.    Retention of Fines:
The loss of fines in the formation of dust is one of the basic reasons for the deterioration of a riding surface. Calcium chloride helps stop this surface deterioration by enhancing the binding the loss of fines in the formation of dust is one of the basic reasons for the deterioration of a riding surface. Calcium chloride helps stop this surface deterioration by enhancing the binding together of fines and aggregates and thus forming a stabilized surface.
2.    Reduced Material Replacement Costs:
The replacement cost of lost materials represents an actual loss of road dollars for many highway departments. Often an even more serious factor is the depletion of local deposits of gravel and other surfacing materials. When calcium chloride is applied to an unpaved surface, it coats the fines and aggregates, binding them together to help keep the original surface material in place and thus also to help reduce the need for replacement materials.
3.    Less Blading:
The amount of blading required to patch and reshape a road is directly related to the extent of the deterioration of the road’s surface. A badly deteriorated road surface will require extensive, heavy blading; a stable, consolidated roadway surface will require a minimal light blading. As calcium chloride binds the fines and aggregates together, the treated road materials form a stable, compacted surface that remains intact and requires less blading.
4.    Elimination of Dust Complaints (What?  Moi?):
There is no other phase of highway maintenance that is more appreciated by the driving public and by taxpayers who live and work along unpaved roads than the elimination of dust. Soon after an application of calcium chloride for dust control, the telephone calls and letters expressing concern over dust are replaced by thanks for the smooth-riding, dust-free road surface.
5.    Adaptability to Surfaces:
Almost no two geographical areas have exactly the same composition of material in their road surfaces. However, with proper gradation, calcium chloride can be used on almost all unpaved surfaces (both large and small), including earth, cinders, gravel, sand, bluestone, shale, limestone, clay, graded crushed stone, shell, and other similar local materials.
6.    Increased Safety:
Dust is not only a nuisance but can also be the cause of accidents on unpaved roads. As billowing clouds of dust reduce visibility, the temporarily “blinded” motorist must confront the dangers of unseen potholes, washboard, and other road hazards. Because of its ability to penetrate the road surface and bind fines and aggregates together, calcium chloride greatly reduces the formation of both dust and potholes. The end result is a cleaner, safer, smoother-riding surface.
