SOME CONSIDERATIONS ON THE COMBINATION OF ASPHALT WITH NON BITUMEN-BASED ROADBASES WITHIN THE FRAMEWORK OF RSTO 75

FRAGEN DER KOMBINATION VON ASPHALT MIT NICHT BITUMINOES GEBUNDENEN TRAGSCHICHTEN IM RAHMEN DER RSTO 75

DURING THE PREPARATION OF "GUIDELINES FOR THE CONSTRUCTION OF THE UPPER COURSES OF ROADS - STANDARD DETAILS, PUBLISHED IN 1975 (RSTO 75)" (DOK 21228), AN ATTEMPT WAS MADE TO LIMIT THE CONSTRUCTION TO THAT JUST NECESSARY TO FULFIL ITS PURPOSE. IN ORDER TO REDUCE COSTS DESIGNERS FELT MOTIVATED TO GO TO THE LIMITS OF TECHNICAL POSSIBILITY. THE AUTHOR POINTS OUT SOME QUESTIONS WHICH HAVE RESULTED FROM USING RSTO 75 IN PRACTICE AND WHICH REQUIRE CLARIFICATION IN THE INTERESTS OF FAULTLESS CONSTRUCTION, SINCE HE FEARS THAT SOME BITUMINOUS PAVEMENTS CANNOT FULFIL THEIR FUNCTIONS TO A KNOWN DEGREE OR FOR LONG ENOUGH. SINCE THE CAUSES LIE MAINLY IN THE REGION OF THE BASE THE DETAILS GIVEN DEAL WITH THE CONDITION OF THE DIFFERENT BASECOURSES AND THEIR EFFECTS ON THE WHOLE BITUMINOUS PAVEMENT. SPACE IS DEVOTED TO THE DESCRIPTION OF THE NON-BOUND ROAD BASES WITH REGARD TO UNIFORMITY, DENSITY, STABILITY, QUALITY ASSURANCE, BEHAVIOUR IN CONSTRUCTION AND LONG-TERM BEHAVIOUR CHARACTERISTICS.
