Latex modified asphalt binder + The purchase price
The stability and morphological identification with asphalt binder using latex-modified surfactants mainly changes due to the processes of storage, mixing and placement, which can further affect its prepared rheological and mechanical performance.
What is latex modified asphalt binder?
Recently, natural rubber has attracted the attention of many researchers in the process of preparing bitumen.
This is because Natural Rubber (NRL) shows excellent performance as it is able to withstand cracking and fatigue behavior.
Natural rubber latex (NRL) is similar to biopolymers in nature, with a composition of dispersed rubber particles.
Sani and his comrades.
2019 is Wen and colleagues.
They also found that NRL significantly improves the wear and tear resistance of asphalt pavements.
Specifications of latex modified asphalt binder?
This has prompted previous and new studies to focus on evaluating the capacity, optimal dose of NRL, and the effects of additives on the bonding of NRL-modified asphalt as part of the modification technology in the asphalt industries.
According to previous researchers, the optimal dose of NRL has been determined to be approximately 5-7% by weight of a typical asphalt binder.
Moreover, the modification of a conventional asphalt binder with organic or chemical additives is an option to achieve an economical and environmentally viable alternative to the production of asphalt pavement.
Previous studies proved that the modification of the asphalt binder made by introducing different types of additives such as Evotherm, Sasobit and silane positively affected the physical and mechanical performance of the rubber asphalt binder.
The purchase price of latex modified asphalt binder
However, the focal point of all the above research was mainly on the macro perspective of the performance of the rubber asphalt binder.
Therefore, this study aims to reduce the knowledge gap by considering the conformations and morphology (microstructures) of rubber asphalt binding materials (with and without the addition of surfactant) at the microscopic level.
Conventional Asphalt Binding Machine (PEN 60/70) was purchased from Kuad Kuari Sdn.
Malaysia when the liquid form of NRL was purchased from a local supplier in the northern part of Peninsular Malaysia.
