STATISTICAL ANALYSIS OF ASPHALT CONTENT IN BITUMINOUS MIXES

FACTORS AFFECTING THE QUALITY CONTROL OF BITUMINOUS MIXES ARE REVIEWED. CONTROL OF ASPHALT CONTENT IS A CRITICAL FACTOR IN THE PRODUCTION OF BITUMINOUS MIXES. TEST RESULTS ARE ANALYZED STATISTICALLY IN ORDER TO STUDY THE EFFECTIVENESS OF SPECIFICATION TOLERANCES AND CONTRACT CONTROL. RESULTS OF THE ANALYSIS INDICATE THAT PRESENT SPECIFICATION LIMITS FOR ASPHALT CONTENT ARE TOO NARROW AND SHOULD BE STATISTICALLY BASED. CONTROL CHARTS WOULD CONSIDERABLY IMPROVE DECISION MAKING WITH REGARD TO ASPHALT CONTENT VARIATION. /CGRA/
