Traditional hot-mix bitumen (HMA) has been the essential material utilized as a part of bitumenic paving in past decades. Then again, contrasted with customary HMA mix, warm-mix bitumen (WMA) mix have indicated incredible potential, and offer advantages not given by HMA mix, subsequent to the WMA mix can deliver bitumenic layers at lower temperatures, without compromising pavement performance thereby keeping up its structural integrity all through its normal expected service life when presented to the harming impacts of the environment and repeated traffic axle loads. In this paper, at first the examinations are finished to focus engineering properties of for the most part available aggregates, fillers and VG 10 assessment bitumen for mix design. Marshall Method of mix outline for DBM (Grade II) was gotten to make sense of the perfect bitumen content. For VG 10 bituminous mix perfect bitumen substance is considered for Marshall Mix diagram by addition of 0.25%, 0.5% and 0.75% estimation of warm blend added substance Evotherm J1 chemical is arranged and attempted to focus the key properties as per the codal acquirement. The lab study indicates that Marshall Mix design using WMA blend by the addition of the added substance can be carried out at reduced temperatures at 120°C. Also Moisture susceptibility test is surveyed using boiling point test.
