County’s 2016 Magnesium Chloride Application Starts April 25th

Archuleta County Road and Bridge Crews will start the 2016 Magnesium Chloride (Mag) application April 25th, weather permitting. The application process will begin in the Arboles area starting on C.R. 973 and will end on C.R. 382 in the Chromo area. Approximately 100 miles of County Roads will receive a Mag application. Depending on the application rate crews can complete 5 to 7 miles of road and apply 25 to 30 thousand gallons per day. Generally a crew consists of 4 motorgraders, 5 to 6 water trucks, and 2 flagmen. The Mag supplier provides 2 to 3 transport trucks and the distributor truck.

County crews start to prepare the road by applying an ample amount of water, motorgraders then begin to cut the surface of the road making a windrow of gravel, the windrow of gravel is then spread back across the road surface (5 to 8 loads of water will be used during this process depending on the amount of moisture in the road and the quality of the gravel). At this point the roadway is ready to receive the application of Mag. With the anticipated amount of Mag to be applied this year, it should take the crew around 5- 6 weeks to complete all work.

Due to decreasing budgets the County will only be doing one application of Mag this year. The roads selected to receive Mag in 2016 are roads in the primary system with 200 ADT or more. A list of roads to receive a Mag application in 2016 is available on the County’s web site.
For those roads the County will not be applying Mag, residents may pay for the material cost and the County will perform all necessary work efforts to apply the Mag. This years cost of the product for 1 mile of road is approximately $ 3,063.00. If residents have any questions on purchasing Mag for their road they can contact Yari Davis @ 264-8404.

Deadline for residents to purchase Mag application is April 18, 2016.
