Everything you need to Know about Bridge Abutments

As a part of a bridge, abutments provide vertical supports to bridge substructures at bridge ends, connect bridges with approach roadways, as well as retain roadway base materials from bridge spans. Although other types of abutments and abutments of important bridges may be pretty complicated, design methods and analysis principles are almost the same. This article will look closely at topics related to design of traditional highway bridge abutments. Unlike bridge abutments, earth-retaining structures are primarily designed to sustain lateral earth pressures.

What are bridge abutments?

These things are substructures that support the terminus of bridge substructures. At the same time, it laterally supports the barrier that serves as the approach to the traverse. For river traverses, this thing also protects embankments from scours of streams. It can be made of reinforced or plain concrete.

Five types of abutments

  • Closed
  • Perched or Stub
  • Spill-through or Pedestal
  • Integral End Bents


This type is a full-height wall with wings on each side that retains the full height of approach embankments. This thing minimizes the needed span length of the structure. But there are significant disadvantages, particularly for embankments on soft or unstable foundations or high embankments.

It needs to be constructed before adjacent barriers. Proper compaction of backfills and placements are pretty hard in restricted areas between walls and wing walls. If heavy types of machinery are used to compact backfills, walls may be pushed laterally, as well as out of vertical alignment.

The weight of backfills will help with the compression of soft or unstable soils, as well as with the post-construction settlement of abutments and embankments. If the structure is supported on piles, the compression of the ground in the foundation will produce a down drag. It can cause overstress on the banks. This thing needs to be designed for lateral earth pressures applied by whole heights of dams.

Perched or stub

Perched or stub is a pretty short attachment that is constructed after the dam has been completed. The barrier can be compacted without attachment interference, and if needed, the attachment construction can be delayed until the foundation soil compression caused by dam loads is completed.

That is why post-construction settlements may be minimized. That is why post-construction settlements or resolutions may be at least minimized. The connector may be backed on spread footings in the dam, drilled shafts, or piles constructed through the filling.

Lateral earth pressures are pretty small compared to the pressures against full-height closed connectors. But longer bridges may be needed compared to full-height connectors. Stubs also are used on natural grounds in cut slopes. Pile, drilled shaft, or pile foundations may be used.

Spill-through or pedestal

Spill-through or pedestal connectors are short stub-type connectors supported on columns or pedestals extending to natural grounds. As with its closed counterparts, the connections need to be constructed before the approach …

Everything You Should Know About Soil Stabilization

You should know that soil stabilization is a process where you want to strengthen it for engineering and industrial purposes. You can boost the stabilization process by implementing sheer strength, which will boost the overall bearing capacity.

As soon as you stabilize it, you will form a solid monolith that will decrease the permeability. That way, you can reduce swelling and shrinking potential, which may harm your property afterward. Remember that swell and shrink potential tend to change depending on the content of humidity and the area you live in.

The main goal is to learn more about soil stabilization products, which will help you throughout the process. Some soils can expand up to ten percent, depending on your option. However, the drastic change can produce a more significant force, meaning it will lead to severe issues to roadways, buildings, and houses.

As a result, you can boost the natural state, which means you will eliminate the need for expensive maintenance and remove/replace situations. In most cases, when you want to create a structural base for parking lots, building pads, and roads, you must chemically treat the soil to ensure its engineering properties.

You can use various chemicals, including cement and lime-based options. Generally, chemicals rely on pozzolanic reactions to create permanent bonds between particles and soil. That is why pre-project testing is vital because it will help you ensure you get enough products to stabilize everything with ease.

When you incorporate a stabilized layer into a structural design such as pavement, you will increase the expenses overall due to lack of treatment. That way, you can perform non-stabilized soil when considering the construction, design, and materials you wish to use.

Effects and Importance

Similarly, as mentioned above, stabilized soils offer a sturdy and robust working platform. After you finish with stabilization, you can transform weak soil into a permanent one, meaning you should chemically treat it with relevant products. We are discussing the foundation for numerous projects you can choose from on the market.

That way, you will get an option that is not liable to reducing permeability and leaching, shrining, and swelling potential. At the same time, you will also boost freeze-thaw resistance, among other things. You should click here to learn more about soil stabilization before making up your mind.

Simple compaction will offer you dry density, meaning a geotechnical measure that includes the water contents of soils that can affect the property you are building. Apart from that, you will change compaction by reducing plasticity, which is a vital factor to remember. As soon as you reduce the plasticity, you can ensure the soil remains workable and friable.

  • Cost Effective Option – It does not matter whether you wish to create mine haul or any other type of road because constant access is essential for business operations. Numerous stabilization techniques are long-lasting, meaning you do not have to apply the process and maintain the conditions afterward. After a single application, you can ensure the operation

What do people need to consider?

It is pretty easy to fall into the idea of just replacing the existing roof with the newer version. Though it usually makes sense since people know that the current roofing worked adequately until recently, they may be missing a significant opportunity to upgrade the functionality and look of their property’s roof. They need to consider the following:

Roof slope

The surface’s slope is a consideration that may help eliminate some possibilities, especially if it is too low. The slope is the number of inches it rises for every one foot or twelve inches of the horizontal run. For instance, a roof with a four in a twelve-inch slope rises four inches for every twelve inches of the flat run.

Another way of expressing slopes is through a pitch or using a fraction. Based on the span (width) and rise (height), the pitch is rising over the span. For instance, if the house is 38 feet wide and the gable dome has a one-foot overhang on all sides, its span is 40 feet. From the eaves to its peak, it is ten feet high – that will be its rise. Think of it as 10/40 and reduce it to 1/4. The dome will have a 1/4 pitch.

A lot of tiles, shingles, as well as slate-like materials, are approved for dome use with a four in twelve or a steeper slope. Flat- or low-pitched domes need to be topped with materials that do not have seams, like built-up gravel-and-tar or sprayed polyurethane foam composite. If they are not, they will leak when the water stays on the surface.

Weather barrier

Since the property’s roof is its main barrier between homeowners and mother nature, it is imperative to choose materials that will reliably shelter their property. It needs to shed snow and rain, endure the sun, and hold up strong wind for a lot of years. Depending on the orientation and shape of the property’s …
