ASPHALT HIGHWAY CONSTRUCTION

ASPHALTSTRASSENBAU

IN CERTAIN CONSTRUCTION PROJECTS, CARRIED OUT ACCORDING TO THE LATEST STANDARDS, THERE EXISTS CAUSE FOR CONCERN THAT THE ASPHALT SURFACING WILL NOT BE ABLE TO FULFIL ITS PROPER ROLE TO A SUFFICIENT EXTENT OR FOR A LONG ENOUGH PERIOD. THE CAUSE LIES IN THE AREA OF THE ROADBASE. FOR THIS REASON THE PREDOMINANT CHARACTER OF THE ROADBASE AND ITS EFFECT UPON THE WHOLE CARRIAGEWAY STRENGTH IS CONSIDERED AND THE PRACTITIONER IS OFFERED ASSISTANCE IN THE APPLICATION OF THE NEW CODES AND SPECIFICATIONS. THE INTENTIONS AND CONTENTS OF RSTO 75 ARE DISCUSSED TOGETHER WITH A COMMENTARY UPON ITS INTRODUCTION, AND COMPLEMENTARY AND DIVERGING STANDARDS USED IN LOWER SAXONY, BAVARIA AND IN THE TOWNS, INCLUDING OBSERVATIONS ON PREVIOUS PRACTICE. THE QUESTION OF THE CHARACTER OF THE BASE OF ASPHALT LAYERS IS DECISIVE. IT IS CONSIDERED IN RELATION TO THE UNBOUND ROADBASE (UNIFORMITY, COMPACTION, STABILITY, QUALITY PROTECTION, USE DURING CONSTRUCTION AND LONG-TERM BEHAVIOUR) AND ALSO IN RELATION TO WATER BOUND SUB-BASES. FROM THIS ARE SHOWN THE REQUIREMENTS IN THE CONSTRUCTION OF ASPHALT PAVINGS, THEIR TOTAL DEPTH AND THE MINIMUM DEPTH OF THE ASPHALT LAYERS IN RELATION TO DIFFERENT ROADBASES AND THEIR MINIMAL THICKNESSES. ATTENTION NEEDS TO BE GIVEN TO PECULIARITIES IN ROAD CONSTRUCTION. RECOMMENDATIONS AND OBSERVATIONS WHICH SHOULD BE CONSIDERED IN THE CONTEXT OF COMPETITION AND OF PROFITABILITY COMPLETE THE DISCUSSION.
