Railway Sleepers are the transverse members that are laid to support the rails. The Typical components of railway tracks are: Rails, Sleepers (or ties), Fasteners, Ballast (or slab track), Subgrade The Function of Sleepers in Railway: Sleepers hold the rails in proper gauge by fixing them in position. It transfers the loads received from the …

A tunnel is an underground passageway, dug through the surrounding soil/earth/rock and that is enclosed except for the entrance and the exit, commonly at each end. A pipeline is not considered as a tunnel, though some recent tunnels have been using the immersed tube construction techniques rather than making use of the traditional tunnel boring …
Lasers in Highway Engineering are used for various purposes like Right of way measurement, Road profiling, Pavement Surface deflection, Accident spot analysis, Bridge deflection, Making new highway alignment Speed checking etc. The Laser techniques have a higher accuracy because everything is automated, quick in collecting data, computed by a computer and needs less …
Tunnel is the pathway constructed underground or across the hills for the purpose of transportation or irrigation. The construction of tunnels depends upon the factors like ground condition, groundwater, length and diameter of the tunnel, transportation, depth of the tunnel, cost of production, and risk management. The geological investigation decides the mode of excavation, whether …
Soil stabilization is the process of modification of engineering characteristics of soil such as strength parameters and that increases the bearing capacity of the soil. It is mostly done if the subgrade soil is not suitable to carry the structural loads. Soil stabilization increases the shear strength of the soil and also decreases the permeability …
Plastic is everywhere, like air? Probably Yes!! All the packaged material that we are using today, comes in an attractively packaged plastic. Almost one trillion single-use plastic bags are used annually in our world. Now we have to confront this waste problem. “It’s only one straw,” said 8 billion people. Keeping this problem as a …
The pavement is a hard solid layer constructed over the natural soil for the purpose of providing a stable, even and smooth surface for the movement of vehicles. The pavement supports and distributes the wheel loads and provides a good wearing surface. Types of Pavements The pavement is basically of three types: Flexible pavements Rigid …
