Calcium Chloride for dust control

[greenie]

Please... no lectures about the environment. Highway departments use CaCl2 for ice and dust control by the barge load. On gravel roads if applied properly it will draw moisture from the air and gravel and form an almost pavement like surface. One treatment will last for several years if done correctly.
Has anyone tried it on reclaim (recycled asphalt)? I think it would work the same and darken up the surface.

Will the recycle absorb moisture like gravel will? I think that would be the limiting factor on how effective it would be.
