The engines of economic growth depend on good infrastructural facilities, as good roads are the life line of country to meet ever increasing demand of users. In India, the sustained efforts need to be made with respect to quality and quantity of roads in terms of load carrying capacity; performance of pavement, durability, length and economy is needed. The construction of roads using hot mix asphalt increases pollution, hence the dire need to come out with a fruitful solution is utilizing warm mix asphalt which is a fast emerging new technology and has potential to reduce the energy consumption i.e. lowering the mixing and compaction temperatures. Warm mix asphalt can reduce production temperatures by about 30º C to 40º C. Hot mix asphalt mixtures are generally prepared at 160°C or greater temperatures depending mainly on the type of binder used. Study of literature shows very few experimental laboratory research done in the area of warm mix asphalt technologies. In this study, an attempt is made to evaluate the changes in engineering properties of the CRMB 60 with and without warm mix adhesion (zycotherm). Also Marshall Mix design is carried out on CRMB 60 with and without warm mix adhesion in suitable dosages of 0.125% and 0.15% at lower temperature as per the provisions of codal practice, without any compromise with quality.The impression of tests proposes the powerful urge to move WMA into the standard of clearing items as the creation temperature is brought down profiting the asphalt development proficiency and bringing down pollution levels as well.
