Cutting maintenance expense through stabilization
Yet, dust control alone tells only half the story. Because, by keeping fines on the haul road, these particles are left to perform the job of binding the surface together. As you know, fines are a very important part of any unpaved road. They add density to stabilize the surface. And that’s where the second chain reaction of benefits begins.
By keeping the road dense, you create a hard, smooth surface that stays that way. Freeze-thaw damage is reduced, so spring road breakup and subsequent maintenance is reduced. Aggregate remains in place so you save on replacement costs. The crown remains intact to assure proper drainage. That, in turn, leads to fewer potholes and less ravel and roll caused by erosion and washouts. It also leads to reduced maintenance costs in the form of fewer bladings. (One firm reduced bladings from once a week to one every three or four months.)
The final result is a haul road that keeps trucks running at maximum speeds for maximum productivity. You eliminate undue wear on tires, shocks and other expensive equipment and parts. You save by reducing watering runs, bladings and aggregate replacement. The total dollar return can be dramatic.
Calcium chloride is used extensively in oil industry, for treating roads in winter and in cement paint manufacturing.
We manufacture high and consistent quality calcium chloride granules with minimum 94 per cent purity. The granular form helps customer by reducing handling trouble.
