Abstract

Bangladesh is a developing country as well as the number of populations is too much higher. For fulfilling the demand of people, firstly a good transportation system is necessary for our country. Among the all three modes of transport, (land transport (road, rail), water transport, air transport) roadway is mostly used mode of transport in Bangladesh. Bitumen is one of the main courses of roadway pavement structure. It is used as a binder material.

Bitumen is an oil-based element. It is a semi-solid hydrocarbon product produced by removing the lighter fractions (such as liquid petroleum gas, petrol and diesel) from bulky crude oil during the refining process. As such, it is correctly known as refined bitumen. Bitumen is a mixture of dark, sticky, highly viscous organic liquids composed mainly of aromatic hydrocarbons. It is usually black or dark brown in color. The material behavior is dependent on the ambient temperature. The main objective in this paper is to determine the actual values of different grade bitumen used in and around Dhaka city ,to compare the standard values and actual values of different grade bitumen , to select the perfect types of bitumen which are suitable for our country and finally to provide better surface conditions of roadway.

Keywords: Mode of transportation; Bitumen; Pavement; Temperature; Sticky
