Asphalt roads with a smooth surface are generally safer. Traditional pavement frequently fails due to rutting, stripping, cold cracking, and fatigue cracking, which causes the pavement to distort over time. In addition, traditional pavement often has lower performance that the new technologies. Polymer-modified bitumen for asphalt mix has a performance that lasts longer than other types of road pavement, making it possible to have smoother surfaces for increased safety on roadways regardless of the weather. With these benefits provided by asphalt modifiers, your pavement will last longer and continue to be safer and enhanced in the overall quality. The formation of a variety of distresses in the bituminous surfacing is encouraged by the intense traffic that occurs on the streets, the overburdening of cars, and the temperature variance of pavements that occurs as a result of climatic changes. Bitumen is at its most malleable during the summer months, while it is at its most brittle during the winter months. Additionally, in a rising nation such as India, the construction of new roadways is taking place at a rapid rate, which necessitates a significant increase in the demand for construction material that is both economical and kind to the environment. 
According to the findings of a few investigations, the properties of bitumen and bituminous blends can be improved or changed with the addition of particular additional compounds. Bitumen that has been premixed with these added substances/modifiers is referred to as modified bitumen. This article provides in-depth descriptions of the various forms of polymer-modified bitumen as well as their characteristics. It also outlines both the benefits and drawbacks of using it in developing countries, taking into account usage in those countries. The quality of the finished product of asphalt and street surfaces is continually increasing as a result of advancements in the manufacturing process of polymer-altered bitumen (PMB). More than three decades have passed since the invention of modified bitumen, which first came into use in the 1980s. Manufacturers are consistently working to improve the quality of their products' execution by using more stringent quality controls and more cutting-edge manufacturing procedures. The use of roads that are more durable and that perform better currently comes as a result of the widespread recommendation among specialists to incorporate at least 10 percent modified bitumen. 
Through research and confirmed insights of increased general movement volumes, tire weights, overwhelming hub loadings, the pace of activity, ecological and atmospheric changes, and worries, it has been proposed that innovative street development outlines and materials be used. In order to modify the characteristic conductivity of bitumen, polymers were introduced. The ultimate performance characteristics of the altered bitumen that is provided will be significantly influenced by the composition of the polymer that is included, the amount of polymer that is included, the based bitumen cover that is used, and the manufacturing technique that is used. By using the appropriate base bitumen and polymer, one can find, manage, and achieve harmony between the consistence and elastic qualities of a cover. This harmony can be achieved by using suitable bitumen. 
The many benefits of bitumen that has been treated with polymer
- A more durable roadway that has a higher Marshall Stability Value.
- Increased resistance to rains and water that has been allowed to pool.
- There will be no stripping or potholes.
- Improve the mix's bonding by increasing its binding capacity.
- A decrease in the number of pores in the aggregate, which results in reduced rutting and raveling.
- Generate work for rag pickers.
- There is a one hundred percent improvement in the road's durability. One ton of bitumen is saved for every one ton of plastic that is used to construct a road of one kilometer long and three and a half meters wide.
- Adding value to the used plastics that have been discarded (cost per kilogram increases from Rs 4 to Rs12).
- Bring down the price to approximately Rs. 5,000 per kilometer for single-lane roads.
- The costs associated with maintaining the road are virtually nonexistent. There will no longer be an issue regarding the disposal of waste plastic.
The drawbacks associated with polymer-modified bitumen
- During the cleaning process, any toxic substances that were present in the mixed plastic debris would begin to leak out.
- While the process of laying the road is being carried out -: In the presence of chlorine will most certainly produce harmful HCL gas
- Following the laying of the road, it is believed that the first rain will start the leaching process. The plastics will just result in the formation of a sticky coating (mechanical abrasion). After the road has been laid down, the individual components of the road are not static.
In summary, the utilization of modified bitumen will lead to the following outcomes:
- The addition of plastic will cause the bitumen's melting point to rising.
- Be a part of the solution to environmental problems.
Plastic roads would be beneficial in hot and particularly humid locations; nevertheless, the majority of existing roads would still have significant potholes. 
- Researchers have discovered that reusing waste plastics in conjunction with a binder, results in improved performance in terms of both strength and resistance to water.
- There is continued cause for concern regarding the high cost of polymers.
- The cost of bitumen is expected to continue to climb.
- Another element that is taken into consideration is the possibility of natural disasters, such as flooding, that could damage roads.
- Both CRMB and NRMB ought to be actively described to a greater degree.
- The PMB market is still dominated by users from advanced economies. It is important for the local road authorities in developing countries to have a better understanding of the advantages of employing modified bitumen as opposed to normal grades.
- The lifespan of roads will be shortened, and it already has begun to do so, as a result of increased traffic circumstances. The use of modified bitumen can serve both as a preventative measure and, in the long run, as a treatment. It will save tens of millions of dollars in the long run and cut down on the number of resources required for the building process.
- The production of modified bitumen from recycled polymers and rubber contributes to the preservation of the earth and provides benefits to the environment.
