A revision is presented to the procedures and guidelines recommended by FAA for frictional standards involving maintenance of highlyskid resistant runway pavement surfaces at civil airports that havecommercial turbojet aircraft operations. Revision of AC 150/5320-12B presents guidance relative to the visual inspection of runway pavement surface condition, when continuous friction measuring equipmentis not available at civil airports, and the use of continuous friction measuring equipment, when available at civil airports, to monitor the deterioration of runway pavement surfaces. Periodic friction surveys will help identify those areas on the runway that are potentially hazardous conditions for aircraft braking and directional control. Once the deficient areas have been located and the cause of the deterioration identified, corrective action can be determined and expedited by the airport management. Guidance is also given on types of surface treatments that successfully mitigate aircraft hydroplaning potential and maintenance methods used to remove rubber deposits in the touchdown zones of runway pavement surfaces
