1、Designation:D534012Standard Test Method forAirport Pavement Condition Index Surveys1This standard is issued under the fixed designation D5340;the number immediately following the designation indicates the year oforiginal adoption or,in the case of revision,the year of last revision.A number in paren
2、theses indicates the year of last reapproval.Asuperscript epsilon()indicates an editorial change since the last revision or reapproval.1.Scope1.1 This test method covers the determination of airportpavement condition through visual surveys of asphalt-surfacedpavements,including porous friction cours
3、es,and plain orreinforced jointed portland cement concrete pavements,usingthe Pavement Condition Index(PCI)method of quantifyingpavement condition.1.2 The PCI for airport pavements was developed by the USArmy Corps of Engineers through the funding provided by theU.S.Air Force(1,2,3).2It is further v
4、erified and adopted byFAA(4),and the U.S.Naval Facilities Engineering Command(5).1.3 The values stated in inch-pound units are to be regardedas standard.The values given in parentheses are mathematicalconversions to SI units that are provided for information onlyand are not considered standard.1.4 T
5、his standard does not purport to address all of thesafety concerns,if any,associated with its use.It is theresponsibility of the user of this standard to establish appro-priate safety and health practices and determine the applica-bility of regulatory limitations prior to use.Specific precau-tionary
6、 statements are given in Section 6.2.Terminology2.1 Definitions of Terms Specific to This Standard:2.1.1 additional samplea sample unit inspected in addi-tion to the random sample units to include nonrepresentativesample units in the determination of the pavement condition.This includes very poor or
7、 excellent samples that are nottypical of the section and sample units which contain anunusual distress such as a utility cut.If a sample unitcontaining an unusual distress is chosen at random,it should becounted as an additional sample unit and another randomsample unit should be chosen.If every sa
8、mple unit is surveyed,then there are no additional sample units.2.1.2 asphalt concrete(AC)surfaceaggregate mixturewith an asphalt cement binder.This term also refers to surfacesconstructed of coal tars and natural tars for purposes of this testmethod.2.1.3 pavement brancha branch is an identifiable
9、part ofthe pavement network that is a single entity and has a distinctfunction.For example,each runway,taxiway,and apron areasare separate branches.2.1.4 pavement condition index(PCI)a numerical ratingof the pavement condition that ranges from 0 to 100 with 0being the worst possible condition and 10
10、0 being the bestpossible condition.2.1.5 pavement condition ratinga verbal description ofpavement condition as a function of the PCI value.Fig.1shows two examples of PCI rating scales.2.1.6 pavement distressexternal indicators of pavementdeterioration caused by loading,environmental factors,orconstr
11、uction deficiencies,or a combination thereof.Typicaldistresses are cracks,rutting,and weathering of the pavementsurface.Distress types and severity levels detailed in AppendixX1 for AC and Appendix X2 for PCC pavements must be usedto obtain an accurate PCI value.2.1.7 pavement sample unita subdivisi
12、on of a pavementsection that has a standard size range:20 contiguous slabs(68slabs if the total number of slabs in the section is not evenlydivided by 20,or to accommodate specific field condition)forPCC airfield pavement and 5000 contiguous square feet(62000 ft2(450 6 180 m2)if the pavement is not
13、evenly dividedby 5000,or to accommodate specific field condition)for ACairfield pavement and porous friction surfaces.2.1.8 pavement sectiona contiguous pavement area hav-ing uniform construction,maintenance,usage history,andcondition.A section should also have the same traffic volumeand load intens
