Snow and ice pose a significant risk for aircraft ground operation safety. Ploughing and chemical treatment are used for snow removal, but yield long-term detrimental impacts to the airfield infrastructure and environment. A proof-of-concept airfield heated pavement system (AHPS) prototype using near-surface embedded heat wire for pavement anti-icing is presented in this paper. Surface-embedded wires were used to study heat performance and energy warranted to maintain above-freezing slab surface temperatures. This approach concentrated heat energy to the pavement surface. Testing this AHPS prototype contained the following objectives: (1) optimise surface-embedded heat wire configuration, (2) investigate surface temperature distribution and (3) summarise system heating performance in outdoor winter conditions. Preliminary laboratory testing used a 150 mm wire spacing in a serpentine configuration. At this spacing, an energy flux of 142 W/m² produced a 6°C temperature rise in 6 h in a −14°C freezer chest. Sufficient surface temperature rise was attained in preliminary field-testing during the 2015–2016 winter season using a 213.1–697.5-W/m² energy range. Using the presented AHPS prototype, a 25-mm layer of crushed ice melted within 1 h during an experimental ice test.

冰雪对飞机地面运行安全构成重大风险。犁耕和化学处理用于除雪，但是会对飞机场的基础设施和环境产生长期的不利影响。本文提出了一种概念验证的飞机场加热路面系统（AHPS）原型，该系统使用近表面嵌入式热丝进行路面防冰。使用表面包埋的电线研究热性能和能量，以保持高于冻结的平板表面温度。这种方法将热能集中在路面上。测试此AHPS原型包含以下目标：（1）优化表面嵌入式热线配置，（2）研究表面温度分布，以及（3）总结室外冬季条件下的系统加热性能。初步的实验室测试使用了蛇形配置的150毫米金属丝间距。在此间距下，能量通量为142 W / m²在-14°C的冷冻柜中在6小时内产生了6°C的温度升高。在2015–2016年冬季的初步现场测试中，使用213.1–697.5-W / m ^2的能量范围实现了足够的表面温度升高。使用提出的AHPS原型，在实验冰测试过程中，在1小时内融化了25毫米的碎冰层。
