Now let's discuss the types of road materials. Who can explain what metalled and unmetalled roads are?
Metalled roads are made of cement or bitumen, so they withstand weather, while unmetalled roads can get muddy and unusable in the rain.
Very correct! Metalled roads are essential for consistent use, making travel easier year-round. Can you think of when unmetalled roads might be useful?
I guess they could be cheaper to build in rural areas where traffic is low.
Exactly! They serve a critical purpose where cost is a factor. Always remember: 'M.U. for durable, no U for rainy days.'
Strategic Importance of Border Roads

Detailed Summary
In this section, we delve into the classification of roads in India, which is crucial for facilitating transportation and economic development. India possesses the second-largest road network in the world, extending to 62.16 lakh km. The classification can be broadly divided into several categories based on function and capacity:
- Golden Quadrilateral Super Highways: A significant project linking major cities (Delhi, Kolkata, Chennai, and Mumbai) aiming to reduce travel time and foster economic interaction.
- National Highways: These roads connect extreme regions, acting as primary transport routes across North-South and East-West directions.
- State Highways: Connect state capitals with district headquarters, crucial for regional connectivity.
- District Roads: Link district headquarters to smaller towns and rural areas.
- Other Roads: This includes rural roads designed to connect villages with urban centers, with initiatives like the Pradhan Mantri Grameen Sadak Yojana enhancing rural accessibility.
- Border Roads: Constructed and maintained by the Border Roads Organisation, these assess strategic importance and improve access in difficult terrain.
Additionally, roads can be classified based on construction material into metalled (all-weather) and unmetalled (seasonal). Efficient road transport is pivotal for India's economic integration, as it enhances the movement of goods and services, critical for a developing nation.

India has the second largest road networks in the world, aggregating to about 62.16 lakh km (2020β21). In India, roadways have preceded railways. They still have an edge over railways in view of the ease with which they can be built and maintained.
Detailed Explanation
India's vast road network is a crucial part of its infrastructure. With over 62 lakh kilometers of roads, it allows for extensive connectivity across urban and rural areas. Roadways were developed before railways in India, and their construction and maintenance are simpler and more cost-effective compared to railway systems. This is significant as it means more areas can be accessed faster and more efficiently.
Examples & Analogies
Think of roadways like the branches of a tree, spreading in various directions to reach many places. Just like how branches more easily grow to cover a large area, roads can be built flexibly to connect even remote areas, ensuring that people can travel and transport goods.
Advantages of Road Transport

The growing importance of road transport vis-Γ -vis rail transport is rooted in the following reasons: (a) construction cost of roads is much lower than that of railway lines, (b) roads can traverse comparatively more dissected and undulating topography, (c) roads can negotiate higher gradients of slopes and as such can traverse mountains such as the Himalayas.
Detailed Explanation
Road transport has several advantages over rail transport. Firstly, it is less expensive to build roads compared to laying down railway tracks. Secondly, roads can easily adapt to the terrain, meaning they can navigate through hilly or uneven landscapes better than trains. Lastly, roads are capable of managing steep slopes, allowing travel through mountainous areas, such as the Himalayas, which would be challenging for railways.
Examples & Analogies
Imagine trying to move through a forest; taking a winding path (like a road) allows you to find your way through easily, while a straight line may not work at all due to the trees and bumps. Similarly, roadways are like those winding paths that find their way through complex terrains.

In India, roads are classified in the following six classes according to their capacity: β’Golden Quadrilateral Super Highways, β’National Highways, β’State Highways, β’District Roads, β’Other Roads, β’Border Roads.
Detailed Explanation
Indian roadways are categorized into six types, each serving different purposes. Super Highways facilitate fast travel across major cities, while National Highways connect critical areas of the country. State Highways link a stateβs capital to its districts, whereas District Roads connect district headquarters within the area. Other Roads include rural pathways connecting villages to towns, and Border Roads focus on connectivity in border areas essential for strategic purposes.
Examples & Analogies
Consider India's road categories like a postal service: just as letters have different types of mail delivery depending on urgency (overnight, regular, etc.), roads serve varying needs β from rapid transit on super highways to local accessibility via rural roads.

Roads can also be classified on the basis of the type of material used for their construction such as metalled and unmetalled roads. Metalled roads may be made of cement, concrete or even bitumen of coal, therefore, these are all weather roads. Unmetalled roads go out of use in the rainy season.
Detailed Explanation
Roads in India are built using two primary materials: metalled and unmetalled. Metalled roads are durable and can be used in all weather conditions, made from materials like cement and asphalt. In contrast, unmetalled roads often become unusable during rainy seasons, impacting connectivity. Understanding this classification helps us recognize the durability and usability of various road types in different weather conditions.
Examples & Analogies
Imagine a kitchen countertop: a granite surface (metalled road) can withstand hot pots and spills without damage, while a wooden surface (unmetalled road) may warp or get damaged when exposed to water. Similarly, metalled roads are designed to withstand varying conditions.
