Design of NH-10 and NH-73 Byircmethod and their comparison with Aashto Method and Pcamethod
Nowadays, Environment Sustainability and effective use of natural resources is a great concern. To build hundreds of kilometres of roadway it involves huge amount of natural resources and we know that our natural resources are in very limited quantity. To save our limited resources any sustainable approach or any green technology or any method that can let us use our resources effectively is welcomed. One such approach for the sustainability of the environment is presented in this paper through the different pavement design approaches. In recent years, cement concrete pavements are being adopted in many new road projects in India in view of their longer service lives, lesser maintenance requirements and smoother riding surface. In this paper, National Highway-10 (Hisar and Dabwali) and National Highway-73 (Punchkula and Yamunanagar) is designed by three methods i.e. by IRC Method which is followed in India and by AASHTO method and PCA Method which are used in American countries. As the IRC method is partly based on the recommendations of AASHTO method and PCA method, it is required to compare the methods to know which is having more economical approach. Through this paper it is found that the IRC gives relatively less thickness as compared to other methods. By this finding we can say that in IRC method the quantity of materials required such as aggregate, bitumen etc.is less which in turn saves our natural resources and preserves our resources for future use. It is also found that the IRC method is more economical.
