Warm Springs Reservation

• Maintain approximately 100 miles of gravel roads
  for school bus access and residential use. We
  apply 700 tons of Magnesium Chloride in the
  spring at a cost of 65/ton thru the use of a
  contract with the lowest cost bidder. We
  typically have 3-4 bidders for these contracts
  each year. The contractor hauls the product from
  the railhead in Madras, Oregon to the various
  roads and applies with a distributor truck to the
  roadway

Comparison of Road Service

• With Dust Abatement
• Less Surface Grading (once per year)
• Less Surface Loss due to keeping tight surface
  without loss of fines due to traffic
• Higher Travel Speeds and less washboard

• Without Dust Abatement
• More Frequent Bladings (3-4 times per year)
• More surface loss due to loss of fines and
  movement of aggregate to ditches and beyond
• Slower travel speeds and less user comfort
