EVALUATION OF GERMAN AND FOREIGN RESEARCH WORK AND PRACTICAL EXPERIENCE ON THE USE OF AGGREGATES IN ROADS

AUSWERTUNG DEUTSCHER UND AUSLAENDISCHER FORSCHUNGSARBEITEN SOWIE PRAKTISCHER ERFAHRUNGEN UEBER DIE VERWENDUNG VON MINERALSTOFFEN IM STRASSENBAU

THE COUNTLESS NUMBER OF RESEARCH PROJECTS,THESES AND REPORTS ON CONSTRUCTION MEASURES AT HOME AND ABROAD CONTAIN MANY DATA AND FACTS WHICH ARE GIVEN TOO LITTLE CONSIDERATION IN THE PREPARATION OF STANDARDS ETC.,OR HAVE TO BE REDISCOVERED BY MEANS OF NEW RESEARCH PROJECTS.EVEN SIGNIFICANT OLDER WORKS ARE OFTEN OVERLOOKED.THUS THERE IS AN URGENT NEED FOR THE COLLECTION AND CONTINUOUS UPDATING OF EXISTING FACTS AND DATA WITH REFERENCE TO THE PLANNING OF NEW PROJECTS.THE EVALUATION SHOULD COMPRISE: 1 - COMPLETED RESEARCH AND TEST REPORTS ON THE BEHAVIOUR OF AGGREGATES UNDER TRAFFIC,IN BOTH NORMAL AND EXPERIMENTAL ROADS; 2 - COMPLETED RESEARCH REPORTS ON LABORATORY TESTS, PARTICULARLY WITH REGARD TO STRENGTH AND FROST AND WEATHER RESISTANCE; 3 - COMPLETED RESEARCH REPORTS ON DEVELOPMENTS IN TECHNICAL TESTING.
