PRINCIPLES AND MODELS FOR EVALUATING GROUP TESTS AND IN SITU TESTS ON ROADS

ERARBEITUNG VON GRUNDSAETZEN UND AUFSTELLUNG VON REGELMODELLEN FUER DIE AUSWERTUNG VON RINGUNTERSUCHUNGEN UND FELDVERSUCHEN IM STRASSENBAU

THE WORK IS PART OF BROADER RESEARCH INTO THE STANDARDIZATION OF GROUP TEST. TWO DRAFT RECOMMENDATIONS HAVE BEEN CONCEIVED WHICH ARE TO BE INCLUDED IN THE "RECOMMENDATIONS FOR THE STATISTICAL EVALUATION OF THE RESULTS OF TESTS", NAMELY: PART 3 - PLANNING AND UNDERTAKING OF GROUP TESTS, AND PART 4 - EVALUATION OF GROUP TESTS AND CALCULATION OF TEST ERRORS. THE RELATION BETWEEN THE MAGNITUDE OF TEST ERRORS AND THE MAGNITUDE OF TOLERANCES HAS TO BE CLARIFIED.
