A REVIEW ON USE OF WAX MATERIAL FOR ENHANCING PROPERTIES OF BITUMEN

Abstract

Transportation is key to the economic development of every country. There are various modes of transportation are available from which Road transportation is very essential because it provides the feeder service to all other modes. There are mainly two types of pavements are used in road transportation viz. Flexible and Rigid Pavement. Flexible pavement is made up of bitumen, which is by product of distillation of petroleum product. As during the construction of flexible pavement, the mixing temperature for bituminous mix is between 130 to 175 °C as per the grade of bitumen. Now it has been seen that at this temperature, CO2 emission is very high and it is not healthy for the workers. So, bitumen emulsion and cut back are used in the mixed design to decrease the mixing
temperature. One more approach i.e. use of wax is emerging for the reduction of mixing temperature. Many countries are using waxes as admixture in bitumen mix. In this research attempt will be made to evaluate the change in physical properties of bitumen and stability of bitumen mix by adding the wax as admixture in VG30 grade of bitumen.
