Abstract - With increased worldwide worries about the
generating a bio-based renewable technology in which bitumen may be partially replaced and modified by a carbonaceous matter such as bio-char. Bio-char, bio-oil, waste cooking oil, plastic, tyre-rubber, polymer, and other materials may be used as an addition to bitumen or to reduce the quantity of bitumen in the binder mixture.
depletion of renewable resources such as petroleum products, greater attention is being placed on bio-based alternative research and use. To address this, bio-fuel production is underway, with fuels derived from organic waste materials and processed for use in a variety of industries. Bio-mass is the name given to this biological waste. A pyrolysis process is utilized to transform this bio-mass into bio-fuels. Pyrolysis is a method that produces biofuels by heating organic matter or biomass to temperatures exceeding 400°C in the absence of oxygen in a reactor or furnace. Other by-products such as biochar and bio-gases are produced as a result of this procedure. The bio-char obtained is a carbonaceous substance in its entirety. However, in the last decade, no significant attempt has been made to use biochar in pavement applications, particularly as a bio-modifier for asphalt binders. The carbonaceous bio-char obtained during bio-fuel generation through pyrolysis of sawdust, walnut shell powder, and crop straw waste was evaluated as an asphalt modifier/extender to obtain bio-bitumen in this study. The characterization of bitumen binders treated with various amounts of biochar was then carried out (0 percent , 5 percent , 10 percent , 15 percent , and 20 percent by weight of binder). Bio-bitumen (partially replaced by bio-char) was examined and compared to bitumen in terms of consistency, temperature susceptibility, and ductility. To arrive at a conclusion for the above criteria, tests such as penetration, softening point, ductility, and flash and fire point tests were carried out and their findings examined. The addition of bio-char enhanced the temperature resistance, according to the tests. The use of bio-char as a bitumen modifier makes it a potential option, especially in India's hot tropical climate. The use of bio-char to partially replace and modify bitumen helps to address the problem of waste creation from various organic sources. It also provides a commercial benefit for its use in a non-renewable product modification that is a driving force behind the expansion of the world's transportation and highway infrastructure networks.
Because of its carbon composition and form, bio-char, a carbonaceous by-product obtained by converting plant matter to bio-fuels by pyrolysis, effectively changes some properties of bitumen. In this study, bio-char is added to bitumen in the binder mixture to act as a partial substitute.

2. REVIEW OF LITERATURE 2.1 Mohammad, L. N., et al. (2013) In this work, the author had performed comprehensive laboratory evaluation of asphalt mixtures containing bio-binder technology at a content of 20%, 25.5%, 30%, and 50%. Laboratory testing was done to evaluate the rutting performance, moisture resistance, and fracture resistance of the produced mixtures.

1. INTRODUCTION Bitumen is utilized all over the world as a binder in the creation of flexible pavements. The use of bitumen for pavement construction has a number of negative consequences, including environmental consequences, depletion of petroleum reserves, price spikes, and so on. Biobitumen has proven to be a successful strategy for
