· Slag asphalt can, therefore, be used most advantageously in those areas where there are demands for noise reduction in densely populated areas. The good friction values referred to above depend on the irregular particle form of the slag. The use of studded winter tyres produce considerable wear and tear of the asphalt and also engender particle formation that is harmful to health; in ...Get Price
Influence of Rice Husk Ash and Slag as Fillers in Asphalt ...
The optimum asphalt content (%) in case of slag and stone dust are same while for rice husk ash (%), the same is slightly higher. It is seen that maximum stability is observed by rice husk ash followed by stone dust and slag as filler materials. The value of retained stability of the asphalt concrete mixture using stone dust, rice husk ash and slag are %, % and % ...Get Price
