The occurrence of bitumen deposits in Nigeria has been estimated to be about 42 billion tonnes, almost twice the amount of existing reserves of crude petroleum according to Nigerian Investment Promotion Commission (NIPC). The failures of the Nigeria bituminous pavements are not only due to increase in traffic but also due to extreme climatic conditions prevailing in the country. For proper planning and usage of Nigeria bitumen for construction of roads in Nigeria, there is the need to upgrade and optimise the bitumen in order to meet the foreign international standard for constructing Nigerian pavements. The polymer modification of the bitumen can improve the quality of binders and enhance the properties of binders used for the construction of pavements.
