Replacement of Bitumen with Pine Resin

Abstract

In the construction world, most flexible pavement constructions use synthetic asphalt made from crude oil and well-known as conventional asphalt. Therefore, to find more environmentally friendly construction people around the world are very interested in finding a bioasphalt. Natural asphalt (bio asphalt) is an alternative asphalt that is extracted from non petroleum based renewable resources. Some of the sources of bio asphalt are resin, sugar, molasses, lignin, rice, vegetable oil, waste cooking oil, waste engine oil, coconut waste, cellulose, palm oil waste, rubber, starches of corn and potato. Bio asphalt has the ability to replace the conventional asphalt. The bioasphalt is used because of several reasons, such as asphalt mixtures derived from plants and trees could replace petroleum-based mixtures. One of bioasphalt which can be used as an alternative material of conventional asphalt is resin (damar). Pine resin is present in huge amounts in Himachal Pradesh.
