A Study On Use Of Natural Fiber By Dense Grade Bituminous Mixes With Coal Ash

Yendurthy Santhosh, B Khadar Mohammed


Coal-based thermal power plants have been a key source of power generation in India. The prime waste product of a coal thermal power plant is fly ash and bottom ash. Heavy dumping of these waste products causes fatal environment pollution to air, water, and land, besides impairing human health. This research work is done to deliver the optimum use of ash, namely bottom ash as fine aggregate and fly ash as mineral filler with natural fiber ( such as sisal fiber) used to improvise the engineering properties of bituminous paving mixes. For national interest these waste products, which are available easily and abundantly can be used economically for bituminous paving purpose, which ultimately helps in saving the natural aggregate resources of the nation.
