The present invention provides additive compound for warm mix asphalt (WMA) for the paving of road surfaces, whereby the additive compounds facilitate the mixing, lay down and compaction of asphalt mixes at low temperatures while retaining the mechanical properties of the asphalt composition. Further, the present invention provides a process of synthesis of the additive compounds. Additionally, the present invention provides a warm mix asphalt formulation involving the additive compounds and a method of preparation thereof. The chemical additives of the present invention are liquid surfactants that ensure reduction of internal friction during manufacturing, and subsequently formulations comprising these chemical additives results in reduction of compaction temperature of the bituminous mixtures.
