Cold In-Place Recycling

Find a Contractor/Supplier


As with all road construction projects, keeping residents and road users notified and informed of upcoming activities is helpful in minimizing confusion, motorist delays and complaints. Extra care should be taken to adequately inform the public and other stakeholders regarding the work.

Notification practices vary from agency to agency and from job to job, but some common forms of notification include one or more of the following:

  • Letters and/or emails to all affected parties
  • Hand-delivered notices to properties abutting the project
  • Temporary "No Parking" signs at appropriate intervals on the project
  • Electronic message boards set up in advance of the work
  • Reverse 911 automated telephone messages to property owners
  • Posting project information on the agency's website
  • Social media messaging of the upcoming work
  • Conventional media (TV, radio and newspaper) notices


Notification message content varies, but usually includes the following information to address six basic questions:

  • What? (a brief description of the treatment being used)
  • Where? (the street names and limits of the work for each)
  • When? (the days, dates and hours of work including a proviso for weather or other unforseen delays)
  • Why? (an explanation of the treatment being applied and the expected benefits)
  • How? (a general sequence of construction events including their potential impacts on travel times and roadway use)
  • Who? (the names of those involved with the project including who to contact with questions)


A thoughfully concieved and executed notification plan can greatly enhance public satisfaction with pavement recycling.

General Preparation

  • Patch areas of insufficient support
  • Determine presence of paving fabric and develop plan to address its presence
    • Some types become saturated with asphalt and are hard like a roof shingle, and are milled up easily
    • Other types of fiberglass grids do not break up and can cause headaches when they wrap around the milling drum
  • Lower utilities and/or mark out locations
  • Perform any required pre-milling if the crossfall needs correcting more than 0.5%
  • Set up traffic control so traffic can be safety piloted around the recycling train
  • Remove crack sealant and pavement markings if required
  • Conduct pre-construction personnel training on CIR for agency, contractor, quality assurance, inspectors
  • Clean roadway free of dirt, vegetation, standing water

In urban areas, notify the public about upcoming work. Inform residents that the project allows quick return to traffic, with minimal impact to businesses.
