Use of Rice Husk In Road Construction

Abstract

The potentiality of rice husk as a good source of high technological materials in road construction is the subject of this research. Every year approximately 600 million tons of paddy (after- M. Ahiduzzaman, Rice husk Technologies In Bangladesh) are produced globally. This gives around 120 million tons of rice husk (RH) and 21 million tons of rice husk ash (RHA) annually. Major four uses of rice husk ash are in the steel, cement, refractory bricks and semiconductor industry. Besides these, it can be utilized in several other applications. Emerging trend of using waste material in soil stabilizing or soil strengthening is being working out all over the world in present days. The main reason behind this trend is the excessive production of waste like fly ash, plastics, rice husk ash (RHA) which is not only hazards but also creating deposition problems. Using some of these waste materials in construction practice will reduce the problem in a great extent. This paper will let us study how husk waste can be used in construction of roads. Step by step procedure of various tests conducted on the experimental model section of road block. This project will also conclude about how the use of rice husk in road construction increases the strength, flexibility, durability etc. of the road. Implementation of new innovative technology in construction of roads. (after-  Effect of Rice Husk Ash on Cement Stabilized Laterite)
