SIGNIFICANCE OF VARIATION AS RELATED TO ASPHALT-AGGREGATE MIXES

A REVIEW HAS BEEN MADE OF THE FREQUENCY DISTRIBUTION CURVE AS A MEANS OF ILLUSTRATING THE VARIATION CHARACTERISTICS OF ASPHALT-AGGREGATE MIXES. VARIATION MAY BE CONVENIENTLY MEASURED BY USE OF STANDARD DEVIATION WHICH CAN BE ESTIMATED BY USE OF THE SHEWHART CONTROL CHART. DATA ON SAND GRAVEL, BINDER AND SURFACE MIXES HAVE BEEN PRESENTED IN ORDER TO ILLUSTRATE TYPICAL PLANT VARIATIONS WHEN DEALING WITH SOME OF THE COMMON TEST CHARACTERISTICS. THESE EXAMPLES SHOULD BE USEFUL TO ANY ENGINEER FACED WITH JUDGING AN ASPHALT-AGGREGATE PRODUCT IN RELATION TO SPECIFICATIONS. /AUTHOR/
