Introduction

The modification of asphalt polymers has been a topic of interest in recent years, with a focus on using Liquid Natural Rubber (LNR) combined with Triton X-114 as an emulsifier and phenylhidrazine as an oxidative degradation agent. This study aims to investigate the properties of LNR and its potential as a modification material for asphalt. The use of LNR and Triton X-114 has shown promising results in improving the quality and durability of asphalt, making it a potential solution for the challenges faced by the road construction industry.

Research Methodology

The first step in this study was the synthesis of LNR through a concentrated latex dilution process, where Triton X-114 was used as a surfactant. This process was followed by oxidative degradation, which was carried out at 60 ° C for 72 hours. After that, characterization was carried out to analyze the properties of the resulting LNR using several methods, including molecular weight analysis with the Ostwald and Brookfield viscometer, as well as the analysis of the infrared spectrum (FTIR).

Characterization of LNR

The result of characterization shows that LNR products have typical infrared wave numbers at 3377 cm^-1 for hydroxyl groups (-OH) and 1654 cm^-1 for carbonyl groups (-C = O). FTIR analysis shows that the optimal ratio of asphalt and LNR mixture is 40:60, which is close to the characteristics of the functional group of pure asphalt. The weight of the resulting LNR molecule is recorded at 12,5892 × 10^2, and it dissolves completely in the toluene solvent. By using the Brookfield viscometer, viscosity at 135 ° C is measured and the results are in accordance with the specifications of the 2010 Revision 2012 Revision, where the maximum viscosity value allowed is ≤ 300 cp.

Benefits of LNR Modification

Through this modification, the main purpose of the research is to produce asphalt that is more resistant to extreme temperatures and high traffic loads. In addition, this study aims to reduce the use of conventional asphalt which is increasingly thinning and increasing latex selling value. By using LNR as a modification material, it is expected that asphalt quality can be significantly improved, providing benefits in terms of endurance and performance.

Environmental Benefits

Asphalt modification using LNR and Triton X-114 is not only an innovation in improving the quality of asphalt, but also shows an important contribution in environmental preservation. This process reduces dependence on synthetic asphalt which often comes from fossil energy sources. By using natural ingredients such as latex and LNR, this research supports efforts towards more sustainable development.

Impact on Road Infrastructure

Furthermore, the ability of LNR in improving mechanical and thermal asphalt properties can have a direct impact on the age of road infrastructure services. Asphalt which is more durable means a reduction in the frequency of maintenance and repair of roads, which in turn saves costs and time. This is also very relevant to the challenges faced by many developing countries, where good road infrastructure is an important foundation for economic development.

Material Technology

In the context of material technology, the use of surfactants such as Triton X-114 is a strategic step to create stable emulsions and increase LNR dispersibility in the asphalt mixture. This shows that the multidisciplinary approach in material research can produce effective solutions for complex problems.

Conclusion

Thus, this research not only presents impressive results, but also opens the way for further research on polymer-based material modification and its application in road construction. The quality and durability of asphalt improved through the use of LNR and Triton X-114 can have a positive impact on stronger and more efficient infrastructure in the future.

Future Research Directions

The results of this study suggest that further research is needed to explore the potential of LNR modification in asphalt. Some potential areas of research include:

Optimization of LNR synthesis: Further research is needed to optimize the synthesis of LNR and improve its properties.
Evaluation of LNR performance: The performance of LNR-modified asphalt should be evaluated in various conditions, including high temperatures and heavy traffic loads.

By addressing these research gaps, the potential of LNR modification in asphalt can be fully realized, leading to improved road infrastructure and a more sustainable future.
