As far as using plastics in constructing new roads and highways, this is nothing new. Recently, studies have shed light onto the usage of plastic waste in road construction, specifically, plastic roads. Plastic roads primarily make use of plastic grocery bags, PET bottles and disposable cups reclaimed from landfills as a main ingredient for the
Disadvantages of concrete roads: cost: Concrete cement costs much more compare to bitumen. Saving the projects from the extra costs is one of the most critical elements to consider for the road builders. Sometimes to stop the concrete from drying too early, select chemicals need to be added or wet cloth like a cover.
Why do some countries have started replacing asphalt Roads with concrete? India has started to expand its usage, for instance, if you drive from Pune to Mumbai, you will notice the expressway being beautifully paved in concrete. It not just that even more in almost all the new projects in India they are mostly using
emulsified asphalt mixtures are more beneficial and better than hot mixtures, environmentally, economically, and logistically advantages over hot mixtures. However, the emulsified bitumen is at the attention of the scientist as structural layers due to their deficient performance and proneness to be damaged early by rainfall. Mechanical characteristic of emulsion mixtures can be enhanced and
Most of the industrial activities leave an enormous amount of waste, industries like factories, mines, and mills.

BITUMEN EMULSION – WHAT, WHY & HOW? What is Bitumen Emulsion? Bitumen Emulsion Bitumen emulsion is a mixture of water & bitumen. You might have this question in mind that oil and water cannot mix. The answer is that; this is possible by adding an emulsifier (a surface-active agent) with water before bitumen is added
Tests on bitumen There is a variety of criteria for the assessment of the properties of bituminous materials. These are some of the tests that are conducted to evaluate the features of bituminous materials. 1. Ductility test 2. Penetration test 3. Softening point test 4. Specific gravity test 5. Viscosity test 6. Flash and Fire
Bitumen itself comes from the fractional distillation of crude oil, but that is not the only way of acquiring it, it also exists as deposits naturally. It’s a unique combination of excellent water-proofing, and adhesive properties make it stand out. Therefore, bitumen is being used for various purposes. There are so many benefits to this low-cost
The hugely anticipated completion of the Malindi-Bagamoyo road which connects Kenya and Tanzania has been delayed until the beginning of next year as African Development Bank (AfDB), the ones footing the bill, have yet to appropriate the funds for the project.

Bitumen is Safe The water can quickly drain through the pavement surface due to the bitumen’s porous form. The other benefit of this will be a reduction in the amount of splash and spray from moving vehicles. Therefore it can create excellent visibility in rainy conditions. “utilizing drainage wearing courses, made of porous mixes is
Bitumen is a typical binder consist of different types of materials like carbon and hydrogen. It is used mostly in road construction, and it is usually obtained as a residual product in petroleum refineries after higher fractions like gas, petrol, kerosene, and diesel, etc. are removed.
Ancient Sumerians were the first civilization which started using bitumen in 4000 BC, they used it for different purposes such as sealing their boats and waterproofing towers and construction of buildings (e.g., The Darius Palace in Susa tower of Babel in Babylon) it was also exceptionally used for roadway coating (e.g., .the processional way of Babylon).
