INSULATION OF CEMENT CONCRETE SURFACES /IN DUTCH/

AFTER DENSE BITUMEN-BOUND ROAD SURFACES ARE APPLIED OVER CEMENT CONCRETE, IRREGULARITIES MAY OCCUR IN THE FORM OF BLISTERING AND DISPLACEMENT. THESE DEFECTS CAN BE OBVIATED BY AN INSULATING SYSTEM, WHICH CONSISTS OF (A) A BINDING LAYER, (B) A LOW WIDE-MESH GLASS FABRIC, AND (C) A LAYER OF FILLED BITUMEN RUBBER MIXTURE. THE BINDING LAYER IS OBTAINED BY COATING THE CAREFULLY CLEANED, SMOOTH AND DRY CONCRETE SURFACE WITH APPROXIMATELY 0.2 KG/SQ M OF A BITUMEN SOLUTION MODIFIED WITH SYNTHETIC RUBBER AND PLASTICIZERS. AFTER THE BINDING LAYER HAS DRIED, A WIDE-MESH GLASS FABRIC DEVELOPED EXCLUSIVELY FOR THIS PURPOSE, IS ROLLED OUT ON IT. THE GLASS FABRIC IS A COMBINATION OF STAPLE FIBERS AND MONOFILAMENTS, WEIGHING ABOUT 0.08 KG/SQ M. THE GLASS FABRIC IS COVERED WITH 5.7 KG/SQ M OF INSULATING COMPOUND, WHICH IS USUALLY LIGHTLY COVERED WITH FINE MINERAL AGGREGATE (2/5 MM GRIT PREHEATED OR BITUMEN-COATED). /TRRL/
