Utilization of waste materials from marble processing industry for sustainable pavement design

Marble is used extensively in construction industry. During mining and quarrying operations of marble, humungous amount of waste is generated. This gives rise to environmental concerns in the areas surrounding the quarry due to unorganised waste disposal system. Marble waste in form of marble dust,...

Description
Summary:Marble is used extensively in construction industry. During mining and quarrying operations of marble, humungous amount of waste is generated. This gives rise to environmental concerns in the areas surrounding the quarry due to unorganised waste disposal system. Marble waste in form of marble dust, slurry and marble blocks/fragments are dumped randomly contaminating land as well as water bodies near these quarries. This study aims to gainfully utilize marble waste in form of rock fragments as replacement of natural aggregate in pavement layer. Marble stones in the range of 10 mm size were identified and were used to replace the corresponding sized coarse aggregates in DBM grade II layer of flexible pavement. Marshall stability parameters were checked and found to be in range establishing that marble waste as an aggregate could be used successfully in pavement design process.
