Gravel Road Dust Control and Chloride Schedule

RCOC Gravel Road Dust-Control Schedule

     Below is the anticipated 2018 schedule for applying chloride to approximately 760 miles of gravel roads throughout Oakland County.   The schedule is updated a few times monthly beginning in approximately April and ending in October.    
      Please note: These dates are tentative and are subject to a variety of variables which can and do result in changes to the schedule. These variables include availability of equipment and manpower, weather and other factors. 

1. Basic chloriding service for primary gravel roads includes five (5) applications per year dependent on weather and the availability of equipment and manpower

2. Chloride applications are not done on all local gravel roads. They are only done when they are paid for either by the township, homeowners or a combination of both. The township or homeowners choose the number of applications per season and pay a per-application cost. 
3. Questions should be directed to the Road Commission's Department of Customer Services at 877-858-4804 or by emailing   

​Gravel Road Grading Fast Facts:

  • 760 mile of gravel Rds., over a quarter of our roads
  • Only 18 motor graders in the county
  • How many miles each grader can reshape/grade in a day?  Not as many as you would think. Each grader does 5 to 6 miles daily.   Schedule rotation takes 4 to 6 weeks, so if you have been waiting 3 weeks since the last grading, you may still have to wait for a bit.
  • Speed at which graders move – 3 miles per hour
  • Multiple passes necessary to grade the road.  Not completed in one pass.  
  • Very expensive equipment.  Operator needs to be properly trained.  It is an art as well as a science.
  • If grader operators feel pressured to cover more miles, it can also create wash boarding problems.  Needs to be done slow and steady.  Can’t be rushed.
  • Graders need maintenance.  They have mechanical breakdowns.
  • Weather can affect the schedule.  They can’t grade if it is too wet or in driving rain.
  • Chloride applications have to be coordinated with grading to avoid dust problems.
  • Many moving parts to the grading schedule and they like to adhere to it to avoid missing a road.  Like to stick to the rotation.
  • SLOW DOWN!   Once the road is graded, slow down!  The smoother surface will last longer.
