WIDERA - CONCRETE FOR THE RECONSTRUCTION AND REPAIR OF ROAD SURFACES, PARTICULARLY IN BUILT-UP AREAS /IN GERMAN/

IN ORDER TO RECONSTRUCT OR REPAIR WORN BITUMINOUS ROAD SURFACES IN BUILT-UP AREAS, BUT STILL RETAIN THE SUBSTANCE PRESENT, TEERBAU G.M.B.H. DEVELOPED WIDERA CONCRETE WHICH, OWING TO ITS MINERAL MIXTURE BEING COMPOSED OF A MAXIMUM GRAIN SIZE OF 2, 3 OR 5 MM, AND TO A CAREFUL DETERMINATION OF THE EFFECT OF THE ADHESION PROPERTIES OF A SPECIAL BINDER ON THE ADHESIVENESS AND ROUGHNESS OF THE CHIPPINGS, RENDERS POSSIBLE THE CONSTRUCTION OF DURABLE THIN COATINGS WEIGHING ONLY 25-40 KG PER SQUARE METER. THEREFORE THE HEIGHT OF THE EXISTING CURBS, GUTTERS AND DRAINS DOES NOT HAVE TO BE ALTERED. ONLY SHARP-EDGED, HARD STONES ARE USED, DURING THE CHOICE OF WHICH ATTENTION MUST BE PAID TO A GOOD ADHESION BETWEEN THE BINDER AND MINERAL, AS OTHERWISE THIS TYPE OF SHARP-EDGED STONE IS EASILY TORN OUT OF THE SURFACING. TO PROVE THE SUITABILITY OF THE NEW ROAD CONSTRUCTION MATERIAL DETAILED EXAMPLES ARE QUOTED IN THE ARTICLE FROM WHICH THE PRACTICABILITY OF THE WIDERA CONCRETE CAN BE SEEN. /FG/RRL/
