HYDRAULICALLY BOUND ROADBASES

HYDRAULISCH GEBUNDENE TRAGSCHICHTEN

THE ARTICLE BEGINS WITH A SUMMARY OF THE DEVELOPMENT OF THE CONSTRUCTION OF PAVEMENTS, PARTICULARLY OF ROADBASES, AND CONTINUES WITH A DISCUSSION OF THE REGULATIONS GOVERNING THIS CONTAINED IN TVT 72 AND TVT 74. BY ADDING BINDERS (CEMENT, BUILDING LIME AND EVEN MIXED BINDERS) IT WAS POSSIBLE TO REDUCE REQUIREMENTS GOVERNING THE USE OF MINERAL SUBSTANCES IN UNBOUND ROADBASES. IN ORDER TO ACCOMMODATE CONSTRUCTION TRAFFIC WITHOUT HAVING TO UNDERTAKE ADDITIONAL REINFORCEMENT MEASURES, IT MAY BE NECESSARY TO INCREASE THE PROPORTIONS IN THE CASE OF THOSE BINDERS NECESSARY FOR OBTAINING STRENGTH AND FROST RESISTANCE. RECOMMENDATIONS ARE MADE FOR THE ACHIEVEMENT OF OPTIMAL THICKNESS AND EVENNESS IN THE MANUFACTURE OF AGGREGATES BOTH ON THE BUILDING SITE AND IN THE FACTORY. CRACKING INTERVALS AND WIDTHS HAVE BEEN DECREASED BY A REDUCTION IN THE QUANTITY OF BINDERS USED. CRACKS ARE DIFFICULT TO SPOT WITH CEMENT BINDER AND ARE INVISIBLE WITH LIME. THIS GREATLY ELIMINATES THE PROBLEM OF HAVING TO BUILD OVER CRACKS.
