1. Scope
1.1 This terminology covers definitions for approved stan- dards under the jurisdiction of ASTM Committee E17 on Vehicle-Pavement Systems. Definitions of terms specific to an individual standard are listed in the appendix. For additional information, see Terminology D8, Terminology F538, Special Report 113, and SAE J 2047, or contact ISO, PIARC, or CEN. 1.2 Other publications may reference this terminology for terms used therein. 1.3 The standard containing the term and the responsible subcommittee of Committee E17 is listed at the end of each definition. Revision ofthe listed standard by that subcommittee will include review of the definition and approved changes or additions will be incorporated herein. 1.4 The terms in this terminology standard are listed in categories of the five groups of Committee E17. These are definitions that are in multiple standards in various subcom- mittees in Groups II to V. The structure of E17 is as follows: Group II on Skid Resistance, E17.21, E17.22, E17.23, E17.24, Group III Roughness E17.31, E17.32, Group IV Pavement Management E17.41, and Group V Intelligent Transportation Systems E17.51, E17.52, E17.54. 1.5 This terminology lists the definition as presented in the approved standards. Variation of any term is also listed and referenced to the defined term (for example the term hydroplaning, viscous is also listed and referenced to the defined viscous hydroplaning). 1.6 The term and its elements should appear in the follow- ing order; term; abbreviation; symbol; dimensions of quantities, measurement units; part of a speech; delimiting phrase; statement of meaning, including specifications limits where applicable; cross references to synonyms or related terms; attribution.1.7 This international standard was developed in accor- dance with internationally recognized principles on standard- ization established in the Decision on Principles for the Development of International Standards, Guides and Recom- mendations issued by the World Trade Organization Technical Barriers to Trade (TBT) Committee.
3. Definitions that are in Multiple Standards
index, n—(synonymous with “number in Committee E17 usage, for example; PSI, RN), a number or formula express- ing some property, form, ratio, etc. of the relation or proportion of one amount or dimension to another. (E867, E17.14) D ISCUSSION —“Numeric” and “metric” also have meanings which are synonymous with index. However, either number or index is the preferred term for use in Committee E17 standards. pavement characteristic, n—a physical feature or property of a pavement surface such as type, roughness, texture, and skid resistance. (E867, E17.14) present serviceability, n—the current condition of a pavement (traveled surface) as perceived by the traveling public. (E867, E17.14) present serviceability rating (PSR), n—a mean rating of the serviceability of a pavement (traveled surface) established by a rating panel under controlled conditions. The accepted scale for highways is 0 to 5, with 5 being excellent. (E867, E17.14) traveled surface, n—any man-made, solid surface for vehicu- lar travel, for example, highways, runways, rails, guideways. (E867, E17.14) weigh-in-motion, n—the process of estimating a moving vehicle’s gross weight and the portion of that weight that is carried by each wheel, axle, and axle group, or a combina- tion thereof, by measurement and analysis of dynamic vehicle tire forces. (E1318, E17.52) 4. Definitions of Technical Group on Skid Resistance baselength, n—the length of a segment of a pavement macro- texture profile being analyzed required to be 100 mm. (E1845, E17.23) calibration platform—on a moving platform for applying a force in the contact plane of a tire, and associated means for measuring the applied force. The calibration platform con- sists of a rigid plate with a high friction surface, in contact with the tire footprint, supported on a frictionless, preferably air, bearing. It may also be instrumented to measure vertical forces (loads). (E556, E17.21)
