Direct Liquid Applications

It seems funny to be talking about winter at this time of year. But, for most road agencies, winter maintenance is the single most expensive activity in their budget. In an effort to reduce these cost Great Lakes Chloride will be partnering with Michigan DOT and Kalamazoo County Road Commission to perform winter de-icing using liquids, Calcium Chloride w/BOOST*.

The biggest issue with DLA is that it’s new to snow plow operators and the public. Like anything new, you will need to train crews to use the liquids properly. As with any tool there are times to take it out of the toolbox and times to put it back in.

Training, communication and documentation of your success and failures is important. If someone on your team see’s something going well or that is a problem. Talk about it then, don’t wait until spring or the next season to bring it up, it can’t be corrected then.

ClearRoads has an excellent power point presentation on DLA. Take a look.

This process has been used successfully across the country for over ten years now. The main reasons behind the move to liquids are, bare pavement quicker, faster clean up, increased level of service. To date across the country, DLA has been a salt brine operation. This partnership is two fold, prove the validity of DLA and show that using CaCl2 w/BOOST*, can provide lower operating temperatures, lower application rates, fewer return trips to the shop to refill, quicker clean up, increased service levels and reduced operating cost.

I will keep you posted as to our success.
