Effect of Ceramic Waste and Lime in Road Sub-Base Layer

Abstract

In this work, ceramic waste (CW), lime, and cement were used for the road sub-base layer. This new approach can eliminate the hazards related to inadvisable industrial waste disposal. To this end, various amounts of CW and hydraulic binder ranged from 5% to 15% and 2 to 6%, respectively. The addition of 5, 10, and 15% CW to the soil improves the physical and mechanical parameters of the soil. However, adding 2% to 6% lime to the mixes has a positive influence on connecting the soil particles. Moreover, the addition of CW waste and lime to the soil gave sufficient results in bearing capacity for both soaked and unsoked, which increased about 114% when we used 15% CW with 6% lime and 200% when we used 15% CW with 2% lime and 2% OPC. In terms of resistance, the results also showed that the unconfined compressive strength (UCS) increased 13 times in soaked conditions and 77% in wet conditions. The addition of CW and hydraulic binder offers an enhanced solution for the stabilization of the sub-base layer as it allows for an increase in bearing capacity. Finally, the addition of CW and hydraulic binder can be used as stabilizers to correct the lower bearing capacity and unconfined compressive strength of the sub-base layer.
