Ashish Chauhan | Nitin Thakur "Relative Study on Warm and Hot Bituminous Mixes" Published in International Journal of Trend in Scientific Research and Development (ijtsrd), ISSN: 2456-6470, Volume-4 | Issue-5, August 2020, pp.1239-1248, URL: https://www.ijtsrd.com/papers/ijtsrd33122.pdf

In this work, comparison made between the Warm mix and bituminous mix technology. Warm Mix Asphalt (WMA) technology is one of the solutions which combine energy savings and environmental benefits. It is a modification of the conventional method of construction of flexible pavements which is surfaced with Hot Mix Asphalt (HMA), which involves high mixing temperatures up to 140oC. A bituminous mix essentially consists of coarse aggregates, fine aggregates, filler and bitumen which bind together all the constituents at high temperature. The optimum dosage of Bitubuild WM was found out to be 2% by weight of bitumen and the optimum binder content for the mix was 5.66% for BC samples and 4.68% in DBM samples. No change in optimum binder content was found by addition of warm mix additive. There was a slight increase in densities of mix with addition of warm mix additive. In BC sample, there was an increase from 2.344 g/cc to 2.370 g/cc and in DBM sample, there was increase from 2.369 g/cc to 2.378 g/cc. There was a slight increase in Marshall Stability value with addition of warm mix additive. In BC sample, there was an increase from 21.15 kN to 25.53 kN and in DBM sample, there was increase from 20.17 kN to 22.14 kN.
