The penetration test for bitumen is a laboratory method for grading bitumen based on its hardness. In this test, the amount of penetrating a specific needle into the bitumen is measured.
More than 85% of bitumen is used in road construction. Weather condition affects on bitumen binder. In cold weather, bitumen becomes hard, and the possibility of cracking increases. On the other hand, hot weather causes bitumen becomes soft and sticky.
Components of a road or parts of a road plays an important part in ensuring the safety and service life of a road. Components of a road is designed to meet the design requirements, functional requirements etc. This article is about the components of road/parts of a road and its functions.
Types of rails are mainly divided into three. Double headed rails, bull headed rails and flat footed rails. You will come to know all the important details of each of them with figures in the blog. The advantages of flat footed rails are also vividly described.
Bitumen for road is an important topic to understand the construction of roads. I will walk you through how important bitumen is for road construction. Also, we will see bitumen road layers, different bituminous materials, cutback bitumen, grade of bitumen and properties of bitumen. A comparison between bitumen and tar will also be discussed in the sections.
Concrete road construction involves building durable pavements using cement concrete road techniques, which prioritize strength and longevity. This method uses layered systems called concrete road layers, including subgrade, sub-base, base, and surface layers, to ensure stability and load distribution. Unlike asphalt, road construction concrete offers higher resistance to weather, heavy traffic, and wear, reducing long-term maintenance costs.
Road camber, also known as the cross slope, is the slight curvature found on the surface of a road. This slope is incorporated into the design. Camber in road is designed primarily to aid efficient drainage. Water runs off towards the edges of the road. This prevents waterlogging or puddling. This minimizes risks such as hydroplaning, which can lead to accidents, especially in wet conditions. A properly cambered road contributes to road longevity, as pooling water can accelerate surface wear.
A cable stayed bridge is a modern engineering marvel known for its strength, efficiency, and aesthetic appeal. It uses one or more towers to support the bridge deck through a series of cables, which transfer the load directly to the foundation. Unlike suspension bridges, the cables in a cable stayed bridge connect directly from the deck to the towers in a straight line. This design provides greater rigidity, making it ideal for long spans and challenging terrain.
What is intelligent transportation system?Intelligent transportation system is a hot topic among all civil engineering subjects that has gained popularity and many countries are successfully implementing it. With the rapidly exploding population, ITS has even become a mandatory technique in all countries. Here, we are going to read through the main components of the intelligent transportation system. We will swim through the benefits of intelligent transportation system in the middle, then to uses and challenges of ITS.
The bitumen softening Point Test is done to determine the consistency of bitumen. Bitumen is a viscoelastic material, which means it behaves like both a liquid and a solid state. It does not have a specific melting point. As the temperature increases, the bitumen becomes softer and the viscosity of the bitumen decreases. One of the common parameters for classifying bitumen is the softening point of the bitumen. This property shows at what temperature the bitumen softens.
Bridges can range from modest constructions to massive, eye-catching pieces of art – and everything in between. A bridge serves its sole purpose as long as it transports us across a gap. Types of bridges is an important classification in civil engineering. In today’s blog, we are going to learn different types of bridges in detail.
