The current construction and maintenance guidelines applied to airport pavement in Korea are those of the International Civil Aviation Organization (ICAO), the International Air Transport Association (IATA), and the Federal Aviation Administration (FAA). In order to consider local conditions of airports in Korea, more specific details should be addressed in those guidelines. For example, the design and construction for pavements at airports in Korea follow the specifications of materials for general roads or foreign airport pavement guidelines, as there is no design manual or guideline for the granular base and subbase materials for airport pavement in Korea. In such circumstances, the likelihood of premature failure or accelerated damage increases, as the loading from airplanes is not fully taken into account or the local environmental characteristics are not considered. In addition, concerns in public facility drainage systems have been rising recently in line with the increase in the frequency and scale, caused by the global abnormal-temperature phenomenon, of localized torrential rain and snow. For airport runways, measures to maintain swift drainage systems are especially necessary to ensure safety and prevent flight delays. In this study, the appropriate moisture content and pavement method are analyzed by applying porous concrete developed for a cement-treated base course for securing permeability of airport pavement at an actual construction site. In addition, on-site construction testing was performed to determine the appropriate compaction method and the curing method to minimize cracking by using a compaction facility. To determine the optimal moisture content, a quality-control was performed by measuring the moisture content of porous concrete produced at a batch plant. For this purpose, a speed moisture test (ASTM D 4944) was performed on site because the unit-water content of the porous concrete affects its compaction and finishing. Before compaction, a grader was used to remove fragments on the subbase and then a tandem roller was used to level and compact. After compaction, the porous cement-treated base course, called porous concrete, was placed using an asphalt finisher. The mechanical properties and durability of the porous cement-treated base course with a variation of a degree of compaction: noncompaction, tandem roller moved back and forth once, three times, and five times. The pavement was covered with vinyl according to the curing guidelines suggested by the Korea Expressway Corporation’s highway construction specifications, to prevent evaporation from porous concrete that has relatively low moisture content. After curing, the core was collected to analyze the compressive strength, permeability coefficient, porosity, and freeze–thaw resistance characteristics.
