ASTM WK34964

    Work Item: ASTM WK34964 - Revision of E950 / E950M - 09 Standard Test Method for Measuring the Longitudinal Profile of Traveled Surfaces with an Accelerometer Established Inertial Profiling Reference Test Method for Measuring the Longitudinal Profile of Traveled Surfaces with an Accelerometer Established Inertial Profiling Reference

    (What is a Work Item?)

    Active Standard: E950 / E950M - 09

    Developed by Subcommittee: E17.31 | Committee E17 | Contact Staff Manager



    1. Rationale

    Current standard does not provide objective comparison between profiles No direct relationship to ride indexes Lack of statistical relationship between precision-and-bias and IRI Not sensitive to height sensor foot prints E 950 Class 1 profilers may fail in AASHTO R56 test
