Introduction

Asphalt emulsion is a crucial material in infrastructure development, particularly as a road surface layer. Its development involves the use of surfactants such as alkylbenzen sulfonate and dietolamide, which can improve the quality and characteristics of asphalt emulsion. This study aims to explore the influence of these two surfactants in making more effective asphalt emulsions.

Background of Asphalt Emulsion

Asphalt emulsion is a mixture of asphalt, water, and surfactants that is used as a road surface layer. It is a critical component in infrastructure development, providing a durable and long-lasting surface for roads. The use of surfactants in asphalt emulsion is essential in improving its physical and mechanical properties, such as viscosity, percentage of solids, and functional groups.

The Role of Surfactants in Asphalt Emulsion

Surfactants play a crucial role in the development of asphalt emulsion. They are used to improve the quality and characteristics of asphalt emulsion by reducing its viscosity, increasing its percentage of solids, and modifying its functional groups. Alkylbenzen sulfonate and dietolamide are two common surfactants used in asphalt emulsion.

Alkylbenzen Sulfonate

Alkylbenzen sulfonate is a type of anionic surfactant that is commonly used in asphalt emulsion. It is known for its ability to reduce the viscosity of asphalt emulsion, making it easier to apply and spread. Alkylbenzen sulfonate also increases the percentage of solids in asphalt emulsion, making it more durable and long-lasting.

Dietolamide

Dietolamide is a type of non-ionic surfactant that is also used in asphalt emulsion. It is known for its ability to modify the functional groups of asphalt emulsion, making it more resistant to extreme weather conditions and traffic pressure.

Methodology

This study used a combination of experimental and analytical methods to investigate the effect of alkylbenzen sulfonate and dietolamide surfactants on the characteristics of asphalt emulsion. The study involved the preparation of asphalt emulsion using different ratios of asphalt, alkylbenzen sulfonate, and dietolamide. The characteristics of the asphalt emulsion were analyzed using viscosity testing, percentage of solids, and analysis of functional groups using FTIR.

Results

The results of this study showed that the use of alkylbenzen sulfonate surfactants had a more significant impact on viscosity and percentage of solids compared to dietolamide. The mixture with the asphalt ratio: Alkilbenzen Sulfonate: Water (75:15:10) g produced the highest viscosity of 16,200 CP. Meanwhile, the asphalt mixture: Dietanolamide: Water (75:15:10) g showed a viscosity of 10,000 CP. In addition, a higher percentage of solids was found in the asphalt mixture: Alkylbenzen sulfonate: Water (85.26%), while the asphalt mixture: Dieanolamide: Water reached 83.83%.

Discussion

The results of this study suggest that the selection of surfactant types is very influential in making asphalt emulsion, which can have an impact on the quality and durability of asphalt in its use in the field. The use of alkylbenzen sulfonate surfactants has a more significant impact on viscosity and percentage of solids compared to dietolamide. This shows that the selection of surfactant types is very influential in making asphalt emulsion, which can have an impact on the quality and durability of asphalt in its use in the field.

Conclusion

The use of surfactants in making asphalt emulsion not only aims to improve physical and mechanical properties, but can also affect the ability of asphalt in holding various environmental conditions such as extreme weather, traffic pressure, and other factors that can affect the age of road use. Further research in this field is very necessary to explore the potential for developing asphalt emulsions that are more efficient and environmentally friendly, as well as to find other surfactant combinations that can produce the best performance.

Based on the results of this study, the following recommendations are made:

The use of alkylbenzen sulfonate surfactants is recommended for making asphalt emulsion due to its ability to reduce viscosity and increase percentage of solids.
Further research is necessary to explore the potential for developing asphalt emulsions that are more efficient and environmentally friendly.
