GUSSASPHALT FOR PAVEMENT CONSTRUCTION: TECHNOLOGICAL AND ECONOMIC CONSIDERATIONS

GUSSASPHALT IM STRASSENBAU UNTER TECHNOLOGISCHEN UND WIRTSCHAFTLICHEN ASPEKTEN

Gussasphalt is characterized by a small excess of the bitumen content compared with the voids content of the densely composed mineral structure. In order to ensure the pouring and spreading quality of the material, the chippings must not form a cohesive structure, but must float in the mortar of bitumen, filler and sand. The known advantages of gussasphalt as a pavement surfacing, such as full density from the start, insensitivity to water and salts, possibility of being worn down to the last millimetre, elastic-plastic behaviour, have been supplemented by so-called "Koelner Gussasphalt". In this construction method, developed by cooperation between authorities and contractor, the still hot gussasphalt material is spread with chippings and rolled with a pneumatic tyred roller, whereby kneading of the mass takes place which avoids the formation of channels, caverns and holes in the surfacing, and the danger of bubble formation is therefore decreased considerably. From an economic point of view, gussasphalt represents the optimum surfacing, due to its durability, the short construction time for resurfacing work with only little hindrance to traffic. /TRRL/
