EVALUATION OF QUALITY CONTROL IN MIXING PLANTS FOR BITUMINOUS MATERIALS

AUSWERTUNG DER QUALITAETSKONTROLLEN IN MISCHANLAGEN FUER BITUMINOESES MISCHGUT

SINCE 1971 IN THE GERMAN DEMOCRATIC REPUBLIC INCREASING USE HAS BEEN MADE OF MATHEMATICAL-STATISTICAL QUALITY CONTROL IN BITUMINOUS HIGHWAY CONSTRUCTION OPERATIONS. FOR EVALUATION PURPOSES REFERENCE IS MADE TO KDT - RECOMMENDATION SW15: QUALITY VERIFICATION IN BITUMINOUS CONSTRUCTION. THE SPECIFICATIONS CONTAINED THEREIN ARE BASED ON A VERY FEW PRACTICAL EVALUATIONS. NUMEROUS INVESTIGATIVE RESULTS ARE AVAILABLE FROM WORK CARRIED OUT IN THE PAST THREE YEARS. THIS CONTRIBUTION REPORTS ON THE ANALYSIS OF THESE INVESTIGATIONS. FROM THESE IT IS DEMONSTRATED THAT CERTAIN CHANGES TO THE SPECIFICATIONS ARE NECESSARY IN RESPECT OF THE MEAN DEVIATION AND STANDARD DEVIATION FOR BINDER CONTENT, FILLER CONTENT, 2 MM AND LESS, AND FOR THE WATER ABSORPTION OF CERTAIN MIXES. THE PROBLEM OF COMBINING THE EVALUATED PARAMETERS INTO A COMPLETE DOCUMENT, WHICH WILL PROVIDE CONCLUSIVE JUDGMENT ABOUT THE QUALITY OF A PRODUCT HAS NOT YET BEEN SOLVED. THE SOLUTION OF THIS PROBLEM SHOULD BE GUIDED BY THE USE OF SIMPLE AND COMPREHENSIVE METHODS.
