Surface deterioration of concrete pavements requires maintenance. Highway and airfield pavements exhibit many of the same maintenance issues, but airfields have several additional unique issues and requirements. Among these are petroleum contamination on aircraft parking areas and a high potential for failed concrete or maintenance materials to damage aircraft. To address these issues, commercially available surface-applied treatment products were assessed for use on concrete pavements with particular focus on the special requirements of airfields. Fourteen products encompassing numerous chemistries were evaluated in a full-scale field experiment. The specific objectives of this study were to investigate materials for field application issues, adhesion to concrete (for both clean and oil contaminated concrete), the ability to seal cracks, behavior under aircraft traffic loads including surface friction, and durability over time with exposure to environmental conditions. Test strips of each material were applied to deteriorated concrete slabs. Half of the concrete was intentionally contaminated with oil while the other half was left clean. Simulated aircraft traffic was applied and periodic visual observations and surface friction measurements were made. Two years after material application, a final visual assessment was made. Many of the products performed well on clean concrete; however, oil contaminated concrete detrimentally affected many of them. Of the fourteen products evaluated, two of the epoxy based materials clearly emerged as the best performing.

飞机混凝土路面修补表面处理的全面评估

混凝土路面的表面变质需要维护。高速公路和飞机场的路面也存在许多相同的维护问题,但是飞机场还有其他一些独特的问题和要求。其中包括飞机停放区的石油污染,以及损坏的混凝土或维护材料损坏飞机的可能性很高。为了解决这些问题,评估了可在市场上购买的表面处理产品用于混凝土路面的情况,特别关注飞机场的特殊要求。在全面的现场实验中评估了包含多种化学物质的14种产品。这项研究的具体目标是研究用于现场应用问题的材料,与混凝土的粘合性(对于清洁的和受油污染的混凝土),密封裂缝的能力,飞机交通负荷下的行为,包括表面摩擦以及暴露于环境条件下随时间的耐久性。将每种材料的测试条施加到劣化的混凝土板上。一半的混凝土有意被油污染,而另一半则保持清洁。应用模拟的飞机交通,并进行定期的目视观察和表面摩擦测量。施用材料两年后,进行了最终的视觉评估。许多产品在干净的混凝土上表现良好;但是,受石油污染的混凝土对其中许多人造成了不利影响。在评估的14种产品中,其中两种基于环氧的材料显然表现最佳。将每种材料的测试条施加到劣化的混凝土板上。一半的混凝土有意被油污染,而另一半则保持清洁。应用模拟的飞机交通,并进行定期的目视观察和表面摩擦测量。施用材料两年后,进行了最终的视觉评估。许多产品在干净的混凝土上表现良好;但是,受石油污染的混凝土对其中许多人造成了不利影响。在评估的14种产品中,其中两种基于环氧的材料显然表现最佳。将每种材料的测试条施加到劣化的混凝土板上。一半的混凝土有意被油污染,而另一半则保持清洁。应用模拟的飞机交通,并进行定期的目视观察和表面摩擦测量。施用材料两年后,进行了最终的视觉评估。许多产品在干净的混凝土上表现良好;但是,受石油污染的混凝土对其中许多人造成了不利影响。在评估的14种产品中,其中两种基于环氧的材料显然表现最佳。应用模拟的飞机交通,并进行定期的目视观察和表面摩擦测量。施用材料两年后,进行了最终的视觉评估。许多产品在干净的混凝土上表现良好;但是,受石油污染的混凝土对其中许多人造成了不利影响。在评估的14种产品中,其中两种基于环氧的材料显然表现最佳。应用模拟的飞机交通,并进行定期的目视观察和表面摩擦测量。施用材料两年后,进行了最终的视觉评估。许多产品在干净的混凝土上表现良好;但是,受石油污染的混凝土对其中许多人造成了不利影响。在评估的14种产品中,其中两种基于环氧的材料显然表现最佳。
