Abstracts: Today,The HMA plants causes pollution and emits certain poisonous gases like CO2, CO, NO, etc. So, in order to reduce the emissions, certain methods are used, one of which is Warm Bituminous Mixes (WBM). Warm Bituminous Mixes allows the producers of asphalt pavement material to lower the conventional temperature range at which the material is mixed and laid on the road.WBM solution allows reducing the working temperature of asphalt up to 30oC.Since the start of developing modern WBM technologies, a lot of experiments have been carried out to establish potential benefits of using WBM and evaluating the performance compared to traditional Hot Mix Asphalt (HMA).First research reports are from Europe from mid 90’s and starting from 2002 a lot of testing and field trials have been conducted in US with publically available reports.Various tests on bitumen with WBM were conducted at different dosage content to check its property.
