TRB's Airport Cooperative Research Program (ACRP) Synthesis 22: Common Airport Pavement Maintenance Practices explores how airports implement a pavement maintenance management program, including inspecting and tracking pavement condition, scheduling maintenance, identifying necessary funds, and treating distresses in asphalt and concrete pavements.

An investigation was conducted which resulted in suggested changes to existing Federeral Aviation Adminstration design, construction, and evaluation criteria for civil airport pavements. Through individual studies, design and construction procedures were developed for prestressed concrete, fibrous concrete and continuously reinforced concrete pavements; porous friction surface courses; and pavements incorporating stabilized layers, insulating layers, and membrane-encapsulated layers. Proposals were made for statistical quality control of paving materials. A nondestructive pavement evaluation procedure based on steady state vibratory loadings and measurements of the resulting elastic deflections was developed. An economic analysis was performed to relate pavement upgrading cost to a penalty cost associated with adding gears and wheels to aircraft in order to provide flotation for present-day pavement design criteria. Studies of aircraft dynamic load effects and wheel-path distribution were made. This report summarizes these studies. Individual technical reports are available for all of the above-mentioned studies.
