Design of Highway Alignment

In this post, we are examining the Importance of Highway Alignment and different elements which should have been considered in arranging the highway alignment. The Terms which we talk about here are the most significant and typically go over in highway structuring and arranging. As a structural designer, you should know about these terms. When the arrangement of road construction is chosen, the following stage to chip away at is the highway alignment.

What is Highway Alignment: The situation of the focal line of the highway or the design of the arranged highway line on the ground is called Highway Alignment. Highway Alignment is for the most part stated as two sorts on Highway plans.

Horizontal Alignment: This covers the horizontal way of the road either it's straight or curved or both. Top perspective on road alignment gives horizontal alignment of the road.

Vertical Alignment: This arrangement with the inclinations, slopes and leveling of the ground. Viewpoint view or front view or side perspective on the road alignment causes you to comprehend about Vertical alignment.

Significance of Highway Alignment: Choosing the highway alignment is the most essential piece of road construction. Road construction includes a ton of land securing. When the alignment is fixed and built according to design, it is hard to change it in view of addition at the expense of connecting the area and advancement of costly structures by the roadside. A little mistake in the Highway alignment improves the expense of construction.

The perfect Highway alignment should meet the accompanying rules as follows.

1. The alignment ought to be structured so that the distance between the beginning point and the endpoint of the road ought to be short and straight with fewer curves.
2. The alignment is chosen so that it ought to be anything but difficult to build and keep up. A decent alignment ought to be direct and have less angles and slopes. To accomplish this, a little deviation in alignment is allowed.
3. The alignment ought to be viewed as just when the activity cost, introductory expense and upkeep cost is least.
4. The choice alignment ought to be sheltered during construction, particularly at banks, slopes, bumpy regions and at inclinations.

Components controlling the Highway alignment

Obligatory Points: The control focuses administering highway alignment are called obligatory focuses. These focuses choose where the alignment should pass and where the alignment ought not pass.

How to compute quantity of steel in column footing with BBS

This construction video tutorial will teach you how to estimate the steel quantity in column footing with bar bending schedule.

Column Footing stands for an independent footing or foundation under a column or either equivalent member for delivering the concentrated load by means of uniformly loads to the soil underneath in order that the bearing capacity of the soil is not surpassed and differential settling does not take place. The footing may come in square, rectangular or circular in plan.

The footing may be constructed with brick masonry, stone, R.C.C., steel grill-age etc on the basis of the load to be transferred as well as the bearing capacity of soil. As a result of low bending strength, the footings built with brick, stone or plain concrete need extensive depth to bear heavy loads safely.

The depth of plain concrete footing is minimized significantly with the arrangement of reinforcements at its base to withstand tensile stresses. R.C.C. column footings may com in circular, rectangular or square in plan. The footing is reinforced both-ways using mild steel ribbed bars which are arranged at exact angles to one another at similar distances apart.
