Bituminous roads are among the most commonly used road types in India due to their cost-effectiveness and flexibility. The construction process involves multiple layers, including base preparation, application of bitumen, and surface finishing.
The key stages of bitumen road construction include site preparation, sub-grade compaction, granular base layers, and bitumen application such as DBM (Dense Bituminous Macadam) and BC (Bituminous Concrete). Each layer plays a critical role in the road’s strength and durability.
Advantages of bitumen roads include faster construction, smoother driving surfaces, and lower initial cost compared to rigid pavements. Proper drainage and periodic maintenance further extend the lifespan of bituminous roads.
With increasing demand for connectivity, bituminous roads remain a preferred choice for both rural and urban infrastructure projects.
