1.1 该测试方法涵盖了通过目视调查沥青路面（包括多孔摩擦层和普通或钢筋接缝波特兰水泥混凝土路面）来确定机场路面状况，使用路面状况指数（PCI）量化路面状况的方法。 1.2 PCI是路面维护工程师集体判断的衡量标准。它直接关系到M&R需求，间接关系到路面结构完整性和功能状况指标。PCI不打算取代粗糙度、结构容量、纹理或摩擦的直接测量。 1.3 机场道面PCI由美国陆军工程兵团通过美国空军提供的资金开发 ( 1- 3 ) . 2 并被FAA进一步验证和采用 ( 4 ) 以及美国海军设施工程司令部 ( 5 ) . 1.4 以英寸-磅单位表示的值应被视为标准值。括号中给出的值是对SI单位的数学转换，仅供参考，不被视为标准。 1.5 本标准并不旨在解决与其使用相关的所有安全性问题（如果有）。本标准的使用者有责任在使用前建立适当的安全、健康和环境实践并确定法规限制的适用性。 第节给出了具体的预防声明 6 . 1.6 本国际标准是根据世界贸易组织技术性贸易壁垒（TBT）委员会发布的《关于制定国际标准、指南和建议的原则的决定》中确立的国际公认的标准化原则制定的。======意义和用途====== 4.1 PCI是一个评估路面表面状况的数字指标。PCI基于在路面表面上观察到的损坏提供了路面当前状况的测量，这也指示了结构完整性和表面操作状况（局部粗糙度和安全性）。PCI不能测量结构容量，也不能直接测量防滑性或粗糙度。它为确定维护和修理需求和优先级提供了客观和合理的依据。PCI的持续监测用于确定路面恶化的速度，这允许早期识别主要的修复需求。PCI提供关于路面性能的反馈，以验证或改进当前的路面设计和维护程序。

1.1 This test method covers the determination of airport pavement condition through visual surveys of asphalt-surfaced pavements, including porous friction courses and plain or reinforced jointed portland cement concrete pavements, using the Pavement Condition Index (PCI) method of quantifying pavement condition. 1.2 The PCI is a measurement of the collective judgement of pavement maintenance engineers. It directly relates to M&R needs and indirectly to pavement structural integrity and functional condition indicators. The PCI is not intended to replace the direct measurement of roughness, structural capacity, texture, or friction. 1.3 The PCI for airport pavements was developed by the U.S. Army Corps of Engineers through the funding provided by the U.S. Air Force ( 1- 3 ) . 2 It is further verified and adopted by FAA ( 4 ) and the U.S. Naval Facilities Engineering Command ( 5 ) . 1.4 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.5 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety, health, and environmental practices and determine the applicability of regulatory limitations prior to use. Specific precautionary statements are given in Section 6 . 1.6 This international standard was developed in accordance with internationally recognized principles on standardization established in the Decision on Principles for the Development of International Standards, Guides and Recommendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee. ====== Significance And Use ====== 4.1 The PCI is a numerical indicator that rates the surface condition of the pavement. The PCI provides a measure of the present condition of the pavement based on the distress observed on the surface of the pavement, which also indicates the structural integrity and surface operational condition (localized roughness and safety). The PCI cannot measure the structural capacity, neither does it provide direct measurement of skid resistance or roughness. It provides an objective and rational basis for determining maintenance and repair needs and priorities. Continuous monitoring of the PCI is used to establish the rate of pavement deterioration, which permits early identification of major rehabilitation needs. The PCI provides feedback on pavement performance for validation or improvement of current pavement design and maintenance procedures.
