Improvement of Soil Using Construction and Demolition Waste for Pavement Application
India is in desperate need of landfill space for the disposal of construction and demolition waste (C&DW). Construction waste or debris resulting from the construction, maintenance, renovation, and demolition of residential buildings, large building structures, roadways, bridges, and dams. India produces around 150 million tons of C&DW every year. However, the recycling capacity is about 1.5% which is nearly 6500 tons per day. So, it is important to implement a strategy for reducing, reusing, and recycling C&DW in India. This study presents the efficacy of C&DW for use as a reinforced material mixed with soil in pavement applications. Various index and engineering properties of soil and C&DW including compaction characteristics are ascertained and compared with different proportions of C&DW and soil mixture. Standard proctor test and California bearing ratio (CBR) test were performed on soil, C&DW and their different mix proportions like 0, 25, 50, and 75% of soil replaced by C&DW. The compaction tests showed that the best results are achieved with 50% replacement of soil by C&DW. The CBR values were observed to be increased by 33% in unsoaked condition and 82% in soaked condition considering 50% replacement of soil by C&DW. The paper emphasizes the potential application of C&DW as a sustainable material in subgrade for pavement application.
