Guidelines for Design, Construction, and Evaluation of Airport Pavement Drainage

摘要

Comprehensive guidelines are provided for the design, construction, andevaluation of airport pavement drainage. Procedures for considering climatic effects on airport drainage are described. Brief summaries of several climatic models which can be used to generate temperature and moisture conditions in pavements are presented. A review of the FAA design procedures for airport surface drainage is presented in order to maintain comprehensive coverage of all aspects of drainage in a single report. Pavement surface drainage is discussed in terms of pavement grooving and the use of porous friction courses. Pavement subsurface drainage is discussed in detail. Methods for determining the sources and quantity of water which enter the pavement are provided. Procedures for designing subbase drainage layers, blankets and filter layers have been presented. Based on the sources and quantity of water which enters the pavement, methods for selecting and sizing the subdrainage collectors and outlets are discussed. Both the used conventional circular pipe systems and prefabricated geocomposite subdrainage (PGS) systems are described.
