STATISTICAL EVALUATION OF HIGHWAY MATERIALS SPECIFICATIONS

A STATISTICAL EVALUATION OF SOME OF THE MAJOR HIGHWAY MATERIALS SPECIFICATIONS IS REPORTED. THE DATA FOR ANALYSIS AND EVALUATION WERE OBTAINED FROM HISTORICAL SOURCES, WITH LIMITED AMOUNTS FROM RESEARCH SOURCES FOR ASPHALTIC CONCRETE, BASE COURSE, AND CONCRETE CHARACTERISTICS. THE DATA WERE ANALYZED BY COMPUTER AND STANDARD STATISTICAL PROCEDURES. THE ANALYSIS INDICATES THAT (A) MOST OF THE HISTORICAL DATA TEND TO FOLLOW NORMAL DISTRIBUTION, (B) IN GENERAL, THERE IS CONSIDERABLE VARIATION IN PRODUCTION AND CONSTRUCTION CONTROL FOR DIFFERENT CONTRACTORS, AND (C) FURTHERMORE, THERE IS A LACK OF COMPATIBILITY BETWEEN CURRENTLY USED SPECIFICATION LIMITS AND STATISTICAL PARAMETERS. THE REPORT DESCRIBES THE VARIOUS SINGLE-SAMPLING PLANS FOR LOT ACCEPTANCE. THE USE OF CONTROL CHARTS FOR CONTROL AND ACCEPTANCE OF PORTLAND CEMENT AND ASPHALTIC CONCRETE IS ALSO DEMONSTRATED. /AUTHOR/
