The Highway Engineering
Highway engineering deals with the planning, design, construction, and operation of highways, roads, and other vehicular facilities, as well as their associated bicycle and pedestrian facilities.It estimates the transportation needs of the public and then secures the funding for the project and analyzes locations of high traffic volumes and high collisions for safety and capacity.…

Modes of Transport
The main modes of transportation are by land, water and air. The land has provided scope for the development of road and rail transport. Water and air have developed waterways and airways respectively. Roads or highways include not only the modern highway system but also city roads, feeder roads and village roads.catering to a wide…

Planning & Design Aspect Of Transport Engineering
The planning aspects of transport engineering are related to urban planning and include technical forecasting decisions and political factors. Technical forecasting of passenger travel typically involves an urban transportation planning model, which requires estimates of trip generation (how many trips for what purpose), trip distribution (destination selection). , mode selection (such as which mode is…

Introduction To Transport, Traffic and Urban Engineering
Transport engineering or transportation engineering is the science of safe and efficient movement of people and goods. It is a sub-discipline of civil engineering. Transport plays an important role in the economic, industrial, social and cultural development of any country.Transportation is vital for the economic development of any region since every commodity produced, whether it…

What is Geosynthetics
Geosynthetics is a term used to describe a range of synthetic products that are used to help solve certain geotechnical problems. The term is generally considered to encompass four main products: geotextiles, geogrids, geomembranes and geocomposites. The synthetic nature of the products makes them suitable for use in the ground where a high level of…

What is Geophysical Exploration
Geophysical methods are used in geotechnical investigations to evaluate the behavior of a site in an earthquake event. By measuring the shear wave velocity of a soil, the dynamic response of that soil can be estimated. Several methods are used to determine the shear wave velocity of a site: The cross-hole methodDownhole method (with seismic…

What is Laboratory tests
A variety of laboratory tests can be performed on soil to measure various soil properties. Some soil properties are embedded in the structure of the soil matrix and are not affected by sample deformation, while other properties depend on the soil composition and its composition, and can be effectively tested only in relatively inert conditions.…

What is In-situ tests
A standard penetration test (SPT) is an internal dynamic penetration test designed to provide information on soil properties, while also collecting rough soil samples for grain size analysis and soil classification. go The Cone Penetration Test (CPT) is performed using an instrumented probe with a conical tip, which is hydraulically pushed into the soil at…

What is Soil samplers
Soil samples are taken using a variety of samplers; some provide only disturbed samples, while others can provide relatively undisturbed samples.Shovel: Samples can be obtained by digging out soil from the site. Samples taken this way are disturbed samples. Hand/Machine-driven auger: This sampler typically consists of a short cylinder with a cutting edge attached to a rod…

What is Soil sampling
Borings come in two main varieties, large-diameter and small-diameter borings. Large-diameter borings are rarely used due to safety concerns and expense, but are sometimes used to allow a geologist or engineer to visually and manually examine the soil and rock stratigraphy in situ. Small-diameter borings are frequently used to allow a geologist or engineer examine…
