Abstract: The increase of environmental concerns has been a promising force behind the existing study on zycotherm-SP2 (ZT-SP2) as part of the possibilities to decrease air pollution in the construction sector through the use of warm mix asphalt (WMA) modern technology. This paper, therefore, provides a modern technology for using ZT-SP2 on WMA concrete. The novel aspect of this work is the alteration of asphalt binder by the use of a ZT-SP2, a revolutionary warm mix additive product. With the help of the eco-friendly material ZycoTherm, asphalt may be produced at lower temperatures between 10 and 15 degrees Celsius, and at lower densities between 30 and 40 degrees Celsius. Published research has shown that adding CBA improves the structural performance of asphalt concrete pavements. Several studies have been made to enhance many types of WMA technologies (chemical, organic, and foaming additives) however, conflicting outcomes have been reported for several recognized features. All experiments were done in a laboratory setup. The summary of the results showed that the use of a ZT-SP2 dose of not more than 0.1% enhances the performance of WMA concrete. An additional in-situ study is needed to prove the performance of ZT-SP2 in real situations.
