Failures in Rigid pavements

Rigid pavements, also known as concrete pavements, are commonly used in road construction due to their durability and long service life. However, like any other infrastructure, rigid pavements can experience failures over time. These failures can be attributed to various factors such as design flaws, construction issues, environmental conditions, and...

Explain CBR method of flexible pavement design

The California Bearing Ratio (CBR) method is a widely used test for evaluating the strength and bearing capacity of flexible pavements. It is a measure of the relative strength of a subgrade soil or aggregate base course material compared to that of a standard crushed stone base. The CBR method...

Failures in Flexible pavements

Flexible pavements, also known as asphalt pavements, are widely used in road construction due to their ability to withstand heavy traffic loads and provide a smooth driving surface. However, like any other infrastructure, flexible pavements can experience failures over time. These failures can be attributed to various factors such as...

Classification of macadam roads

Macadam roads, also known as macadamized roads, are a type of road construction method that was popularized by Scottish engineer John Loudon McAdam in the early 19th century. This method revolutionized road construction by introducing a new approach to building durable and cost-effective roads. Macadam roads are classified based on...

Advantages and Disadvantages of Flexible Pavement

Advantages and Disadvantages of Flexible Pavement Flexible pavement is a type of road surface that is designed to flex and stretch under traffic loads, providing a comfortable and durable driving surface. It is made up of a series of layers, including a base course, a binder course, and a surface...

Advantages and disadvantages of Rigid pavements

Advantages of Rigid Pavements: 1. Durability: Rigid pavements, also known as concrete pavements, are highly durable and can withstand heavy traffic loads for an extended period. They have a longer service life compared to flexible pavements, which require more frequent maintenance and repairs. 2. Strength: Rigid pavements have high flexural strength, meaning they can...

Explanation of different shapes of tunnels

Types of tunnels with detailed explanation:- The Circular section offers greater resistance to external pressure and highly suitable for unstable ground such as sand or soft clay. They are not used as traffic tunnels because they require more filling to make flat base, hence used for carrying water and sewage...

Group Index of Soil in Highway construction

Group Index of Soil in Highway construction Group Index(G.I) of soil is used to classify the fine grained soils and for checking their suitability as highway subgrade material. It assigned a particular group to a soil. The quality of a subgrade soil is inversely proportional to G.I., means higher G.I...
