Runway Rubber Buildup and Friction Testing Explained
Published
Understand runway rubber buildup, pavement texture and friction testing. Plan cleaning around measured conditions, a test section and clear acceptance criteria.
Runway rubber buildup is a pavement-maintenance issue. Aircraft tire deposits accumulate in touchdown areas, and heavy coverage can conceal the surface texture. Wet conditions make the loss of friction especially important. Airport maintenance teams use inspections and measurements to plan the response.
For cleaning inquiries, see runway rubber removal with dry ice blasting. The project scope should identify both the deposit-removal task and the measurements required to accept the work.
Why runway rubber buildup matters
Runway pavement relies on its surface characteristics for friction. Rubber deposits can cover the texture that is already there. The objective of removal is to expose that underlying surface while preserving the pavement.
Grooves are another part of the runway surface. Record their condition and any deposit coverage in the treatment plan. Also identify worn areas and retained markings before defining the cleaning boundaries.
FAA guidance describes rubber deposits as a persistent runway contaminant. It connects heavy deposit coverage with reduced braking capability when runways are wet. Read the pavement-maintenance discussion in FAA AC 150/5320-12C.
Use these points to frame the maintenance request. Describe where the deposits occur and provide the relevant inspection records. Then state which areas need treatment and which require a separate pavement review.
Separate inspection photographs from friction measurements
Photographs document deposit locations and help explain the cleaning scope. Before-and-after images also record the visible change. However, they do not replace a friction survey.
Continuous friction measuring equipment is commonly shortened to CFME. A testing provider uses this equipment under a defined procedure to produce a pavement-friction record. The report belongs with the other project documents.
For a useful comparison, ask the provider to identify the device, calibration record, test route and operating conditions. Keep those details with the results. Also record the location of the cleaned treatment area.
A photograph and a friction report answer different questions. The photograph shows the visible condition. The survey records the measured pavement response under the test conditions.
Set the criteria before cleaning
First, identify the guidance and specification that apply to the project. Next, name the person responsible for interpreting the measurements. Include the acceptance criteria in the work scope.
Do not select one friction number and apply it to every testing system. Device and procedure details matter. The Tri-Service runway rubber removal manual organizes CFME guidance around equipment, training and maintenance measurements.
For military facilities, use that manual alongside the applicable service documents and contract. For other airports, obtain the operator’s testing procedure and project requirements. The cleaning contractor and testing provider need the same written endpoint.
Then decide how the report will be delivered and reviewed. Identify the required treatment-zone references, supporting photographs and cleaning records. Assign the airport’s acceptance and return-to-service decisions before the visit.
Use a representative test section
The test section connects the proposed cleaning method to the actual runway. Choose an area that represents the pavement and rubber-deposit conditions in the production scope.
Record the test boundaries, cleaning settings, elapsed time and collection method. Also document the retained pavement, markings and fixtures. This provides information for both the scope and the schedule.
FAA guidance recommends a contractor demonstration of removal without pavement damage. It also recommends friction measurements after cleaning. Those steps are distinct from judging the surface by appearance alone.
For dry ice blasting, the process uses a soft, non-abrasive cleaning medium. It introduces no wash water, solvents or hard grit. Cold Jet’s process guide explains the cleaning characteristics. The runway test establishes the result for the specific pavement and deposit.
Keep the cleaning scope separate from pavement repair
Identify existing cracks, worn areas and other pavement-condition issues in the work plan. Then distinguish the rubber-removal task from any repair or resurfacing requirement.
If the inspection report identifies more than deposit coverage, bring the findings to the airport’s pavement team. Name any additional work separately. This keeps the cleaning quote tied to a defined removal objective.
Also distinguish rubber removal from marking removal and lighting maintenance. Each task has its own retained surface and inspection needs. State those boundaries before building the contractor’s work sequence.
Document runway rubber buildup and cleaning results
Keep the treatment map, cleaning record and testing report together. Include the date, runway identifier, deposit condition and method used. Record the work completed and any untreated areas.
Next, retain the provider’s test details with the results. Use the airport’s maintenance program to plan the next inspection and measurement. The interval should follow the operator’s records and applicable procedures.
For scheduling, read planning runway rubber removal during an airport closure. For the process options, review runway rubber removal methods compared.
Prepare a runway rubber buildup cleaning inquiry
Send the runway identifier, pavement material, treatment area and deposit photos. Add the recent inspection or friction report when approved for sharing. Finally, provide the required work window and acceptance criteria.
