To Study Experimental Analysis of Replacement of Aggregate with Recycled Concrete Aggregate in Bituminous Concrete

Abhishek Meshram [2] | Dr. Alok Goyal [2]

Abstract: Nowadays, there is a noticeable decline in the availability of natural aggregate resources, both fine and coarse. Consequently, there is a growing emphasis on the recycling of aggregate, specifically through the repurposing of concrete as a replacement for aggregate in certain proportions. Recycling dismantled building concrete aggregate not only offers environmental benefits but also holds economic advantages. In my thesis, I present an experimental study focused on the practicality of utilizing recycled concrete aggregate (RCA) as a partial substitute for aggregate in bituminous macadam (BM). By employing the Marshall Mix design method, I assessed the engineering properties of BM mixtures incorporating various percentages of RCA. The test results indicated that the performance of BM mixtures is influenced by the presence of RCA, primarily due to its higher porosity and absorption characteristics compared to granite aggregates. However, the engineering properties of BM containing a specific amount of RCA displayed acceptable trends and were able to meet standard requirements. Nonetheless, it is crucial to exercise caution and carefully consider the properties of BM mixtures containing RCA in order to achieve desired performance characteristics.
