Study on Behavior of Warm Mix Asphalt Using Zycotherm

Manjunath S Sharanappanavar

Abstract: The asphalt industry has been aware of the energy savings and environmental benefits warm mix asphalt technologies. Keeping these two reasons in view, they came up with an idea of using warm mix asphalt technology which uses chemical additive. Using this technology, they can considerably reduce the temperature of asphalt pavement when compared to normal asphalt pavements. Warm mix asphalt is one technology that is gaining popularity in the industry in response to this effort. The Warm Mix Asphalts (WMA) which is produced, laid and compacted in temperature which is lower than conventional mix. The WMA is produced by mixing chemical additives to the conventional mix to improve the pavement performance. In this study an attempt is made to compare the Marshall properties of WMA produced with the chemical additive Zycotherm with an additive dosage rate of 0.1 % by weight of the binder and increasing the stability and workability of bituminous concrete mix by reducing OBC And Finding the best mixing percentage of Zycotherm to obtain a fully compacted bituminous layer for Semi Dense Bituminous cover (SDBC). The laboratory study concludes that Stability & Marshall properties were improved for the WMA mix by the addition of the additive.
