Laboratory Evaluation of Bituminous Concrete Mix using Envirotac-SC as a Chemical Additive

The economy of a nation is mainly governed by the transportation sector. In India, there has been a piercing upturn in the populace resulting in increased traffic which also increases the loading on the flexible pavement Due to that demand for better pavement to withstand all the worse condition also increased. So additives are added to improve the properties of the bituminous concrete mix. In the present investigations Envirotac-Sc chemical is added to the bitumen and the bitumen’s physical and engineering properties are investigated with different percentages of chemical by the weight of the bitumen. As the result, the additives improve the virgin bitumen’s performance. Then the bituminous concrete mix is prepared by using virgin bitumen VG-10 and also by addition of Envirotac-Sc to the bitumen and tested as per Marshall Method of mix design. As the conclusion, the existence of Envirotac Sc chemical in the bitumen improves the properties of the bitumen. Hence, the bitumen helps in resisting distress such as rutting and cracking. The decrease in the penetration with the increase in the Envirotac-SC further confirms the improvement of bitumen properties. The stability of the BC mix prepared by addition of Envirotac-Sc found little more than the conventional BC mix. However, some recommendations are commended in order to attain superior results.
