Experimental Study on Utilization of Recycled Concrete Aggregates in Bituminous Concrete
Rapid urbanization, the implementation of new infrastructure projects, and the development of the construction industries all result in the generation of massive amount of construction and demolition waste. Pavement construction costs a huge amount of money and uses a lot of resources. To minimize investment and lower the need for raw materials, it is crucial to implement a tried-and-true methodology for building and maintaining roads. Using recycled materials for construction of roads can be a sustainable solution. This can address a number of issues, such as the use of land for waste disposal, resource depletion, landfill overflow, water pollution, and so on. The goal of the current study is to examine the characteristics of recycled concrete aggregates (RCA) and potential applications in bituminous concrete (BC). Marshall mix design was used to examine the properties of bituminous mixes using RCA as coarse aggregates versus mixes comprising just virgin aggregates. In this paper, investigation on the possible utilization of RCA in bituminous concrete proposes preparation of modified mixes by replacing 10, 20, 30, 40, and 50% virgin aggregates with RCA at varying bitumen percentages of 5, 5.5, and 6%. It was observed that although the stability value of the mix decreases as the RCA content rises, the measured volumetric properties for the RCA samples were more stable than for conventional mixes and fell within acceptable recommended limits. At a bitumen content of 5.5%, RCA can be used as a 30% replacement for natural aggregates in bituminous concrete. Material cost analysis also suggested that the utilization of RCA in road construction is an economical and sustainable solution.
