Gravel Road this spring with no Dust Control Treatment in 2011. Note the rutting and potholes.
This is the same gravel road, difference is this section was treated with 38% Calcium Chloride the previous season for dust control. As noted in a previous post, Calcium Chloride not only helps with dust control, it adds with compaction and prevents frost heaves and spring break up. This saves time and money for road agencies in added gravel, trucking and grading.
I will be doing additional research on the problems associated with Sodium Chloride (salt) and the damage it causes during the spring thaw and break up of gravel roads. This is becoming a real problem for agencies using mineral well brine and oil field brine with large amounts of salt being added to these roads during each application.
