Gravel Road Dust Control and Chloride Schedule

RCOC Gravel Road Dust-Control Schedule 

The 2022 gravel road schedule for applying dust chloride to just over 750 miles of gravel roads throughout Oakland County schedule is now available.  
 For the latest schedule: CLICK HERE
 The schedule is typically updated 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 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 or 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:

  • RCOC has jurisdiction over approximately 755 miles of gravel roads in Oakland County  (more than a quarter of our roads)
  • RCOC operates independently from Oakland County general government and does not receive any property taxes for its operations. Money for road maintenance comes from state fuel taxes, vehicle registration fees and income tax. The state, through a formula established by the Legislature, sends an allocation to RCOC. 
  • RCOC has only 19 motor graders in the county (graders do need routine maintenance and occasionally have mechanical breakdowns)
  • Each grader can reshape/grade 5 to 6 miles in a day. At this pace, it takes four to six weeks, for crews to get around to all the gravel roads. So, if you have been waiting three weeks since the last grading, you may still have to wait for a bit.
  • Speed at which graders move: 3 miles per hour.
  • A grader must make multiple passes to grade the road -- the grading is not completed in one pass.  
  • Graders are very expensive pieces of equipment. Additionally, the operator must be properly trained; grading  is an art as well as a science.
  • When grader operators feel pressured to cover more miles and try to rush the work, it can also create "washboarding" problems.  Grading needs to be done slowly and steadily.  It can’t be rushed.
  • Weather can affect the schedule. Roads can’t be graded if it is too wet or in driving rain.
  • Chloride applications have to be coordinated with grading to avoid dust problems.
  • There are many moving parts to the grading schedule, and operators like to adhere to the schedule to avoid missing a road.  
  • SLOW DOWN!   Once the road is graded, slow down! The smoother surface will last longer.
  • Following a major storm event, staff will address primary (heavier-traveled) gravel roads first and work their way toward roads that carry less traffic, such as subdivision roads.
