Types of road construction are significant to understand the category of roads and their characteristics. In this blog, we will find out the details of 5 types in detail. Whitetopping is the coating of a layer of Portland cement concrete on the existing asphalt pavement. Depending on the thickness of the concrete sheet and if the layer is bonded to the asphalt substrate, whitetopping is divided into different types
Road pavement structure: Road is the most important structure that decides the economic growth of a country. The road structure to be constructed based on the traffic requirements, climatic conditions of the area, terrain, etc. The road structure has to withstand abrasion loads and climatic and terrain conditions without failure. This article is about the components of a flexible pavement structure.
Transport is the main source of GHG. An electric vehicle can be used as an alternative source. We will find out the basic details of EVs along with its challenges and solutions. EVs are defined as vehicles that use an electric motor for propulsion. Although EVs offer several advantages and can be used in different application, there are several challenges in the popular use of them.
Types of pavement are mainly four. I will show you the each of them in detail with the advantages and disadvantages. The flexible pavement layer may reflect the non recoverable as well as recoverable deformations of the lower layer including subgrade on the upper layers and also to the pavement surface. The vertical compressive stress is maximum on the pavement surface directly under the wheel load and is equal to the contact pressure under the wheel.
Electronic toll collection is one of the best advancements of Intelligent transportation system in transportation sector. We will see what is electronic toll collection in the next section. Later, I will walk you through four subsystems of ETC. They are automatic vehicle classification (AVC), violation enforcement system (VES), automatic vehicle identification (AVI) and transaction processing, which includes a back office and customer service center. The advantages, cost and disadvantages of ETC will also be discussed
Coning of wheels is an interesting topic in railway engineering. In this blog, we will see the theory of coming of rail wheels, starting from what is coning of wheels. What is coning of wheels? The space between the inner borders of wheel rims is by and large kept less than the measurement of the track.
Types of Gauges in railway is a mandatory topic to touch upon when you study railway engineering. In the blog, I will take you to a trip through the main types of gauges in railway which are broad gauge, metre gauge and narrow gauge. You will also see the major factors that affect the choice of gauges.
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.
Components of railway track are rail section, sleepers, ballast, rail fastenings and subgrade and embankments. I will walk you through each of them in detail. You will get to learn about the functions of rails, functions of sleepers, functions of ballast and about fastening of railway. The rail provide a hard, smooth and unchanging surface for the passage of heavy moving loads.
Alignment of road is very important during the road construction. We will sweep through what is highway alignment and then the requirements of highway alignment. Followed by that, I will walk you through factors affecting alignment of road. Then, I will describe obligatory points in depth with figures. In nutshell, l am going to make you savvy in the topic.
