With the ambitious construction of road networks under the National Highways Development Programme (NHDP), State Highways Improvement Programmes (SHIPs), Bharat Nirman, Pradhan Mantri Gram Sadak Yojana (PMGSY), and other programmes, India’s road transportation infrastructure is fast developing. Other types of highways and airports are also greatly increased. As the main corridors are required to accommodate very heavy traffic-both in terms of quantity and axle loading-the rapidly rising Indian economy will increase demand for a road transport network with a high quality pavement construction.
The National Highways Authority of India (NHAI) has laid roads under the Golden Quadrilateral project, as well as the North-South and East-West corridors projects. According to the Ministry of Shipping, Road Transport and Highways’ result budget, 5,694 kilometers of road-laying and four-lining out of a total of 5,846 kilometers were slated for completion in the current fiscal year. While these road development projects contribute significantly to the addition of infrastructure assets, their construction and subsequent maintenance phases need a large number of acceptable paving materials.
Currently, the bulk of Indian roads are flexible pavements with bituminous layers. Previously, there was a lack of cement, thus India opted for flexible pavements with bituminous toppings from bitumen emulsion manufacturing companies. Flexible pavements are now favored over cement concrete roads because they may be reinforced and enhanced in stages as traffic increases. Another significant benefit of these roads is that their surfaces may be milled and repurposed for restoration purposes. Flexible pavements offered by bitumen emulsion manufacturing companies are also less expensive in terms of initial investment and upkeep.
The Importance of Bitumen Properties
The used pavement ingredient materials and their inherent qualities always influence and affect the durability and long-term good performance of pavements to a higher extent. Hence it is always recommended to purchase bitumen from superior bitumen emulsion manufacturing companies. The upper layers of a pavement construction are critical for load/stress reduction and structure protection. They are envisioned as layers of high-quality materials in the building and are built appropriately.
Because stone aggregates and bituminous binder are vital constituents in bituminous pavements, they must be of high quality, making their selection from various bitumen emulsion manufacturing companies an important task that is often overlooked. The primary prerequisite for creating practical layer mixes is the application and adhesive characteristics of bitumen, as well as suitable proportioning with stone aggregates. The petroleum crude is refined to produce asphaltic bitumen. It is the most expensive and crucial component of the bituminous mix.
When striving to improve the performance characteristics of bituminous mixes, it is critical to evaluate the qualities of bituminous binders as well as the bitumen concentration in the mix. The construction industry is interested in selecting good bitumen emulsion manufacturing companies and employing the correct sort of bitumen to create durable pavements with a lifespan of 10-15 years, particularly for BOT (build, operate, and transfer) projects.
Conclusion:
To achieve required performance during the design life of roads, the quality of road building materials in all levels of the pavement structure is critical. Furthermore, maintenance treatments used during its service life need bitumen of the required grade; hence, bitumen specification becomes critical for assuring the performance of bituminous surfaces. As a result, the viewpoint of bitumen quality in terms of addressing road performance must be integrated in the specification of bituminous materials based on rational considerations rather than empirical factors and always left on reliable bitumen emulsion manufacturing companies.
