Introduction Of Asphalt:
Role of Asphalt Industry in the Economy Of World is water-repellent material, and it has compact structure and can’t dissolve in water. And meanwhile it has good plasticity, adhesion ability and bond force with mineral materials. So that it is assumed to be well waterproof. Asphalts are the varieties of naturally occurring bitumen. The asphalts are also produced as a petroleum byproduct.
Many types of asphalts occur as viscous impregnations in sand stones, silt stones, and lime stones. They are of variable consistency, ranging from highly viscous fluid to a solid. Asphalts occur with or without mineral matter. Most of the asphalts are of marine origin. And consist of the high molecular weight compounds normally present in petroleum residue.
Asphalt pavement has been extensively used in expressways all over the world. Because of its many advantages such as rapid construction, driving comfort and safety, low noise levels etc. However, some disadvantages of asphalt pavement cannot be ignored. As an organic substance asphalt is vulnerable to aging due to the influence of thermal, oxygen, light, water and other external factors.
Role Of Asphalt in Industry:
Role of Asphalt Industry in the Economy Of World is a commonly used material in the construction industry. It is a black, sticky substance. That is made by mixing bitumen a byproduct of crude oil with aggregates such as sand, gravel or crushed stone. Asphalt is used in a variety of applications including road construction, roofing and waterproofing.
Road Construction:
Asphalt is widely used in road construction because of its durability and flexibility. It can withstand heavy traffic and extreme weather condition without cracking or deteriorating. Asphalt pavements provide a smooth and safe driving surface that reduces tire wear and fuel consumption. Asphalt is also easy to install and maintain, which makes it a cost effective option for road construction.
Roofing:
Asphalt is also used in roofing applications because of its waterproofing properties. Asphalt shingles are the most common type of roofing material used in residential buildings. They are made by coating a fiberglass mat with asphalt and adding mineral granules for added protection. Asphalt shingles are durable, lightweight and easy to install. They also come in a variety of colors and styles to match any architectural design.
Waterproofing:
Asphalt is also used in waterproofing applications. It is commonly used as a sealant for concrete and masonry structures to prevent water intrusion. Asphalt sealants are also used to seal cracks and joints in pavement to prevent water from seeping in and causing damage. Asphalt is also used in the construction of reservoirs, dams, and canals to provide a waterproof barrier.
Environmental Impact:
Asphalt production can have a significant environmental impact. The extraction and processing of crude oil to produce bitumen releases greenhouse gases and other pollutants into the atmosphere. The production of asphalt also requires a significant amount of energy and resources. However, there are ways to mitigate the environmental impact of asphalt production.
Benefit Of Asphalt in Economy:
Role of Asphalt Industry in the Economy Of Worldhas several benefits that make it a popular choice in road construction. It is durable, flexible, and can withstand heavy traffic loads. It is also easy to maintain and repair. And it’s dark color helps to melt snow and ice faster, making it safer for motorists. Additionally, asphalt is a recyclable material, and its components can be reused to create new asphalt.
