Research Paper on Feasibility of Bitumen and Concrete Blend in Construction of Roads

Abstract

Abstract: A pavement or a road which is smooth, free of any potholes and cracks, easy to maintain and very quick to repair is the most ideal type of a road. But, with the construction of bitumen or concrete roads we don't see that happening, the present roads which are generally constructed using bitumen or concrete has shown many defects in them like cracks, potholes during every rainy season, frequency and difficulty in maintenance, and very difficult to repair them in quick time. So to overcome this situation every year, this project aims at constructing a pavement or a road which is jointless which will minimize lots of defects, minimize potholes, a road which does not require frequent repairs and which is easy to maintain. All the above remedies could be possible if we blend bitumen and concrete together to concrete a road. This project aims at checking the feasibility (to what extent it can be done) of constructing this mix road which is a blend between bitumen and concrete by testing its various parameters. For creating a strong bond between bitumen and concrete, various materials, combination of materials and their different proportions were used. After experimenting and several trials and error methods later, a strong bond between bitumen and concrete was created by using combination of materials and their different proportions. The strength to withstand the load of vehicles was achieved after adding different admixtures into it. Once, the fundamental parameters were fulfilled, it was time to perform different tests on its specimen. The results of tests like flexural, split tensile, compressive and water penetration were all satisfactory. Thus, feasibility check for constructing this mix road was successful.
