Grade Separation and Interchanges
Grade separation is a method developed to avoid the disruption of traffic flow at intersections. Grade separation is adopted at junctions where two or more surface transport axes cross with each other. Different types of grade separation structures, advantages and ...
Retaining Wall Types, Materials, Economy, and Applications
What is a retaining wall? Retaining wall is a structure that are designed and constructed to withstand lateral pressure of soil or hold back soil materials. The lateral pressure could be also due to earth filling, liquid pressure, sand, and ...
Curves in Alignment of Highways – Types of Curves
What is a Curve in Roads? A curve is nothing but an arc which connects two straight lines which are separated by some angle called deflection angle. This situation occurs where the alignment of a road way or rail way ...
Sight Distance in Highway Engineering – Types and Calculations
The visibility of the road ahead of the driver will help in the safe and efficient operation of the vehicles. This will hence demand the geometric design to be highly efficient so that the length of the road is highly ...
What is Geometric Design of Highways and Factors Affecting it?
Geometric design of highway is the determination of layout and features visible on highway. The emphasis is more on satisfying the need of the driver as well as to ensure the safety of the vehicle, the comfort while driving and ...
What are Different Layers in a Bituminous Pavement?
Bituminous pavements are constructed in different layers such as base course, binder course and surface course. These layers are made of different materials and provides different functions to the bituminous pavements.
Highway Surface Drainage System and Its Design
Surface drainage system is most important in Highway engineering. Pavement without proper drainage facilities will not serve for long time. Design of drains for roads and pavements are discussed.
