In this article we will discuss about how to stabilise soil for road construction. Learn about:- 1. Mechanical Stabilization 2. Stabilisation with Additives. 1. Mechanical Stabilization: Rearrangement of the soil grains and densification by compaction is the first approach. The other approach consists of blending two or more available soils to obtain the desired gradation of soil particles for the [...]
In this article we will discuss about how to maintain roads. Maintenance of Highway: A well-constructed highway that is designed for a particular category would need minimum maintenance. The nature and extent of maintenance needed would depend on the degree of deterioration of the pavement, the most common road characteristic used to assess this being the 'roughness'. It is generally [...]

In this article we will discuss about how to measure dryness fraction of steam. Barrel Calorimeter: To get the approximately dryness fraction of steam, a very simple ape called Barrel Calorimeter is used. This consists of a wooden barrel containing cold water. Steam is taken from the pipe through which it is flowing and is condensed in the cold water. [...]
In this article we will discuss about the sheet metal manufacturing process and its operation types. Introduction to Sheet Metal Work: Most of the sheet metal work is done on presses where a die and punch or other formed tools are required. In press work large force is applied on thin sheet metals to give the required shape or to [...]
In this article we will discuss about how to Calculate calorific value of fuels. Meaning of Calorific Value: The calorific value of a fuel is amount of heat liberated by its complete combustion. For solid and liquid fuels, calorific value is expressed in kJ/kg, whereas for gaseous fuels it is expressed as kJ/m3 where m3 is normal cubic metre measured [...]
Get the answer of: What is the process of making and manufacturing bricks? Following considerations govern the selection of a brick field for the manufacture of bricks: (i) It should be linked up with the communicating roads so that the materials can be conveyed easily. (ii) It should be situated on a plain ground. (iii) It should be so selected [...]
Following three distinct operations are involved in the manufacture process of of fat lime: 1. Collection of Lime Stones 2. Calcination of Lime Stones 3. Slaking of Burnt Lime. 1. Collection of Lime Stones: The lime stones of required quality are collected at site of work. For fat lime, the percentage of impurities in lime stones should not exceed 5 [...]
Index Properties: In order to evaluate the suitability of a soil for use as foundation or construction material, certain physical properties have to be determined. These properties help to classify the soil and assess its engineering behaviour and are called index properties. There are different soil classification systems based on index properties of the soil. The tests carried out in [...]
List of Vacuum Pressure Measuring Devices [with formula]! 1. Mercury Manometers: These are of two types: i. Differential and Optical Lever Manometers, which are modifications of the ordinary mercury manometers, with more sensitive methods of observation and measurement. These are suitable for measurement of pressures up to 10-3 mm. ii. McLeod Gauge, which is a standard device of its type [...]
