Abstract

Taxiway flexible pavements are subjected to high shear stresses from slow-moving aircraft with large wheel configurations, making mixture stability and resistance to permanent deformation critical performance requirements. Asphalt Concrete (AC) and Stone Mastic Asphalt (SMA) are commonly used wearing course mixtures; however, their performance characteristics under taxiway loading conditions may differ significantly. This study presents a comparative evaluation of the Marshall performance of AC and SMA mixtures designed in accordance with Federal Aviation Administration (FAA) specifications for taxiway pavements. Laboratory experiments were conducted using the Marshall mix design method to determine key parameters, including stability, flow, Marshall Quotient (MQ), Voids in Mix (VIM), Voids in Mineral Aggregate (VMA), Voids Filled with Asphalt (VFA), and Optimum Asphalt Content (OAC). The results indicate that the AC mixture exhibits higher average Marshall stability, reflecting superior load-bearing capacity, whereas the SMA mixture demonstrates lower flow values, indicating greater resistance to permanent deformation. The OAC of the SMA mixture is higher than that of the AC mixture due to its stone-on-stone aggregate structure and larger VMA. These findings highlight the trade-off between structural stiffness and deformation resistance in selecting wearing course mixtures for taxiway pavements and provide technical insights for mixture selection based on FAA performance requirements.

Abstract

Runway pavements are subjected to heavy and repetitive aircraft loads, requiring asphalt mixtures with high stability and deformation resistance. Aggregate gradation plays a critical role in controlling the mechanical performance of Asphalt Concrete (AC) mixtures. This study investigates the effect of FAA dense-graded and BBA open-graded aggregate gradations on the Marshall characteristics of AC mixtures for airport runway applications. Laboratory Marshall testing with 75 blows of compaction was conducted to evaluate stability, flow, Marshall Quotient (MQ), voids in mix (VIM), voids in mineral aggregate (VMA), and voids filled with asphalt (VFA). The results show that the optimum asphalt content (OAC) of the FAA mixture is 5.0%, while the BBA mixture requires a higher OAC of 5.6%. Under optimal conditions, the BBA mixture achieved a higher stability value (2270 kg) than the FAA mixture (2120 kg), indicating superior load-bearing capacity. The BBA mixture also exhibited higher VMA (15.82%) and VFA (77.38%), reflecting a stronger aggregate interlocking structure combined with higher asphalt content. These findings demonstrate that aggregate gradation philosophy significantly influences the mechanical performance of runway asphalt mixtures. The BBA gradation shows greater potential for use as a runway wearing course where high stability and resistance to deformation are required.
