INVESTIGATION ON INDUSTRIAL BY-PRODUCTS AS A HIGHWAY MATERIAL FOR SUSTAINABLE DEVELOPMENTArul S., Ranjith K., Vidhya K., Manishankar S. and Manirasu R.Abstract In roads and highway construction conventionally soil, stone aggregates, sand, bitumen, cement etc. are used in construction after enhancing its strength, stability and durability. Very large amount of soil and aggregates are required and they are also not available. So we started to use alternative materials. The researchers are also searching for various option materials for thruway development, and modern waste item is one such class. In continuation various industrial waste products are used and some enhancements are also done with those alternative materials. Stabilization method highlighted in this project mainly to enhance the inherent strength of wastes like fly ash and crushed blast furnace slag (cbfs). Fly ash and blast furnace slag was collected from Rourkela steel plant (rsp). The characteristics, strength properties of different mixes are determined. The strength parameters that are the unconfined compressive strength and California bearing ratio value for different mixes compacted were evaluated. Further these mixes are blended with lime varying as 0%, 2%, 4%, and 8% and the unconfined compressive strength values are determined after a curing period of 0, 7 and 28 days. Similarly, the soaked cbr values of lime stabilized mixes at 0%, 2%, 4%, and 8% are determined after a curing period of 0 and 28 days. The effects were studied with that combination. The mix with 80% slag shows higher value as compared to 100% slag in the mix. Further the desired strength required for different components of road can be achieved by stabilizing the mix with appropriate lime. |
