SURFACE TREATMENTS WITH BITUMEN EMULSIONS

OBERFLAECHENBEHANDLUNGEN MIT BITUMENEMULSIONEN

BITUMEN EMULSIONS ARE PREFERRED AS BINDERS FOR SURFACE TREATMENT. THE KNOWN EFFECTS OF BITUMEN EMULSIONS ARE DESCRIBED AND THE COMPLETE BINDING PROCESS IS ILLUSTRATED DIAGRAMATICALLY. THE QUALITY OF THE SURFACE TREATMENT IS DEPENDENT ON THE CORRECT CHOICE OF MATERIALS AND ON THE EXECUTION OF THE WORK. AN EFFICIENT CONCEPT FOR MATERIAL CHOICE AND FOR THE CARRYING OUT OF THE METHOD, UNDER NORMAL CONDITIONS, IS PRESENTED. IT IS BASED ON THE USE OF SPECIALLY APPLIED SPRAYED EMULSIONS U 70 K, AN APT CHOICE OF PARTICLE SIZE 2/5 MM, 5/8 MM AND 8/11 MM, AS WELL AS MECHANISED HANDLING. FROM EXPERIENCE, SINGLE SIZE CHIPPINGS FINISH SHOULD CONTAIN THE FOLLOWING PROPORTIONS OF MATERIAL: 2 KG/M2 BITUMEN EMULSION U 70 K AND 16 KG/M2 DOUBLE BROKEN AND DOUBLE SCREENED CHIPPINGS 5/8; TWO SIZE CHIPPINGS COATING WITH SIZES 8/11 MM AND 2/5 MM SHOULD CONTAIN: 2.2 KG/M2 BITUMEN EMULSION U 70 K, 15 KG/M2 DOUBLE BROKEN AND DOUBLE SCREENED CHIPPINGS AND 3 KG/M2 DOUBLE BROKEN AND DOUBLE SCREENED CHIPPINGS 2/5 MM. THE NEW METHOD OF PRODUCING SPRAYED PROTECTIVE COATINGS IS CHARACTERIZED BY THE MECHANICAL APPLICATION OF THE BINDERS AND CHIPPINGS AND PRODUCES PERFECT RESULTS.
