STATISTICAL QUALITY CONTROL OF HIGHWAY CONSTRUCTION MATERIAL

A SUMMARY OF THE FINDINGS OF SEVERAL INTERIM REPORTS ON STATISTICAL QUALITY CONTROL OF HIGHWAY COSTRUCTION MATERIAL IS PRESENTED. THE ADVANTAGES AND LIMITATIONS OF THE PRESENT CONTROL PROCEDURES ARE DISCUSSED. THE WORK DONE TO DATE INDICATES THAT STATISTICAL SPECIFICATION CAN BE USED TO THE ADVANTAGE OF THE HIGHWAY ENGINEER. DURING THE STUDY SOME OF THE PROBLEMS IDENTIFIED THAT NEED ADDITIONAL ATTENTION WERE: PERSONNEL TRAINING, REPRODUCIBILITY OF TESTS, PRESERVATION OF ENGINEERING JUDGMENT, AND COST OF ADMINISTRATION. POSSIBLE SOLUTIONS TO THESE PROBLEMS ARE DISCUSSED INCLUDING DETERMINING THE PRECISION OF TEST METHOD AND PROCEDURES FOR ASSURING THAT A LABORATORY IS IN OPERATIONAL CONTROL. ONE SPECIFIC PROCEDURE, QUALITY CONTROL BY THE MOVING AVERAGE USING CONTROL CHARTS, IS PROPOSED. IT IS ANTICIAPTED THAT THIS PROCEDURE WILL PROVIDE CONTROL WITHOUT INCREASING COST WHILE AT THE SAME TIME SUPPLYING MANAGEMENT INFORMATION IN THE FORM OF CHARTS AND GRAPHS. /AUTHOR/
