Experimental Study on Application of Red Gypsum and Blast Furnace Slag in Pavement Construction

Industrialization leads to a range of environmental challenges related to the disposal and storage of by products, making the proper disposal of industrial waste a significant global concern. The industrial waste can be used in various applications including stabilization, construction of pavements and embankments, etc. This study investigates the potential usage of industrial waste like red gypsum and blast furnace slag (BFS) in pavement construction with lateritic soil and quarry dust. Lateritic soil with different percentage of red gypsum and BFS shows a remarkable positive change in different soil parameters such as unconfined compressive strength (UCS), compaction, and California bearing ratio (CBR). By analysing the results, it is observed that it is ideal to mix two kinds of industrial waste by reducing the usage of natural resources, and thereby it can be effectively utilized in the construction of pavements.
