碩士 === 國立成功大學 === 土木工程學系碩博士班 === 101 === Domestic airport is mostly rigid pavement of the runway, if they meet the useful life and the Crack (cracking) And the fall (fault) , Fillers and aging damage condition may affect aircraft taking off and landing for security and passenger comfort, the existing road surface paving on flexible pavements is a direction worth considering, for a solid pavement, surface aircraft load resistance of materials you want to use. This study adopts modification III -type asphalt mix United States civil aviation authorities (FAA) airport of dense graded specifications (P401) and AAPTP Report recommended that the airport of stone mastic asphalt (SMA) grading specifications, nominal maximum size of three different (NMAS 9.5, and12.5 and 19mm) natural material SMA with the design, and uses the NMAS 19mm nominal maximum particle size and compare natural stone and converter dense asphalt concrete mix design . In the experiment, using sand texture measurement view and British Pendulum Number (BPN) micro-textured pavement skid resistance evaluation to measurement, use cantabro test evaluation at all levels enjoy stripping in nature with the simulation of airport runway foreign object damage (FOD), And different days Cure time soaking wheel track rutting test of ability of the test to assess their resistance against water and filter meet runway high load, high security and high service life of asphalt concrete pavements. This experiment five graded on engineering properties of no significant difference in the comparison, in comparison of slip resistance, NMAS 19mm SMA Relative excellent performance, airport runway paving need to provide the aircraft when landing the ability of friction, so that aircraft can quickly and safely slow down the runway, so anti-sliding property in this very important. By anti-water against nature of comparison in the can seen, rut depth although has excellent differences, but due to rut depth are is less than 2mm, actually five kind of level enjoy are has quite good of anti-rut capacity, stripping nature test is assessment airport runway other a items focus,FOD is airport runway security of important issues, from experimental comparison in the know, stripping nature as nominal maximum grain diameter of rose and improve, Nominal diameter 19mm grade has a higher risk of foreign object damage. Integrated above results, by this experimental of results recommendations using BOF replaced natural material rough grain material of airport intensive enjoy as airport runway paving of basement strengthened layer to bear aircraft of high load to improve of using life, and using NMAS 12.5 of SMA as runway of wear layer to provides aircraft enough of friction and against FOD of security.
