ransportation engineering is the application of technology and scientific principles to the planning, functional design, operation and management of facilities for any mode of transportation in order to provide for the safe, efficient, rapid, comfortable, convenient, economical, and environmentally compatible movement of people and goods (transport). It is a sub-discipline of civil engineering and of industrial engineering.
Segmental Construction Of Bridge – Seminar (with ppt) Submitted by : Gaurav Jhalani Introduction of Bridge A bridge is a structure built to across a obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Designs of bridges depending on the function of the bridge, length … Read more
Different Types of Bridges and Criteria of Site Selection Definition A bridge is a structure built to span physical obstacles such as a body of water, valley, or road, for the purpose of providing passage over the obstacle. Designs of bridges vary depending on The function of the bridge, The nature of the terrain where … Read more
Types & Functions Of Bearings for Bridges Function Of Bearings Bridge bearings are used to transfer forces from the superstructure to the substructure, allowing the following types of movements of the superstructure: Translation movements; are displacements in vertical and horizontal directions due to in-plane or out-of-plane forces like wind and self weight. Rotational movements; cause … Read more
Selection Criteria For Bridge Site The choice of the right site is a crucial decision in the planning and designing of a bridge. It may not be possible always to have a wide choice of sites for a bridge. This is particularly so in case of bridges in urban areas and flyovers. For river bridges … Read more

Rehabilitation of RC, Steel and Pre-stressed Bridges Introduction Modern bridge infrastructure comprises of primarily concrete (reinforced or pre-stressed) and steel structures. Over the service life of a bridge, its constituent materials are continually subjected to fatigue and wear-tear due to dynamic vehicular loads. Overloading due to increase in wheel loads and regular exposure to aggressive external environment … Read more
IRC Method Of Concrete Mix Design About IRC 44-1976 Primarily implemented in the design of Concrete Rigid Pavements on Road Construction. Flexural strength is more often specified than compressive strength in the design of concrete mixes for pavement construction. Basic Differences from IS method Strength Criteria– Checking of Flexural strength have more priority than Compressive … Read more
Bridge Site Selection & Guidelines SURVEY • Social Feasibility Survey and • Technical Survey Both surveys are of equal importance. The social feasibility survey establishes community ownership and responsibility, and the technical survey ensures that bridge construction is sound and safe. SOCIAL FEASIBILITY SURVEY Level of local participation • size of area of influence • … Read more
Bridge Engineering – Components of Bridge Structures A bridge is a structure providing passage over an obstacle without closing the way beneath. The required passage may be for a road, a railway, pedestrians, a canal or a pipeline. The obstacle to be crossed may be a river, a road, railway or a valley. Classification of … Read more
