Investigating field performance of airport pavements with and without drainage Summarize the best of practices through survey of airports and consultants.Įvaluate the effectiveness of subsurface drainage configurations by The objectives of this research would be to In under- or over-estimate of the design thickness. In addition,Īlthough the specification states that certain subsurface drainage layers couldīe considered as base layers in pavement design, the FAARFIELD design softwareĭoes not consider any factors of drainage in the calculation, which may result Practices and to verify the benefits of using such systems. (AC 150/5320-5, G-3.3.1) and Department of Defense specification (Unifiedįacilities Criteria 3-260-02) outline the criteria for requiring a subsurfaceĭrainage system, there has been no study dedicated to summarize the best of The cost of construction and raise the question whether the increasedĬonstruction cost is offset by a proportional increase in pavement performance.Īlthough the Federal Aviation Administration specification The use of such features usually increase Incorporate positive subsurface drainage features into airport pavements toĪddress surface infiltration water. Benefits of Subsurface Drainage System in Airport Pavement Performance
