AGGREGATE PARTICLE SIZES DURING THE COURSE OF BITUMINOUS MIXTURE MANUFACTURE,AND THE DETERMINATION OF WORKING TOLERANLES (PRELIMINARY STUDY)

DIE MINERALSTOFFKOERNUNGEN IM ABLAUF DES HERSTELLUNGS PROZESSES VON BITUMINOES GEBUNDENEM MISCHGUT UND DIE ERFASSUNG ARBEITSMAESSIGER TOLERANZEN (VORSTUDIE)

THE RESEARCH IS TO EXAMINE IN DETAIL THE COURSE OF THE PROCESS OF MANUFACTURE,FROM THE PROPORTIONING OF THE AGGREGATES TO DRYING,MIXING,LOADING AND TRANSPORT.THE PROPORTIONING OF THE BINDER IS ALSO TO BE COVERED TO A CERTAIN EXTENT.OF PARTICULAR INTEREST IN THE TESTS ARE THE DEVIATIONS UNDER REPETIVE CONDITIONS IN THE MIXING PLANT. THE REPEATABILITY CAUSED BY THE SAMPLING AND TESTING IS TO BE DETERMINED AND CONSIDERED SEPARATELY.BASICALLY THE PRELIMINARY STUDY IS TO DEAL WITH THE BEST DIVISION INTO INDIVIDUAL PROBLEMS DURING THE CARRYING OUT OF THE STUDIES, AND TO SEE WHETHER THE SETTING UP OF A PROPORTIONING PLANT IN ASSOCIATION WITH THE PLANNED SETTING UP OF AN EXPERIMENTAL MIXING PLANT IS JUSTIFIED.
