Why are Graders Important in Road Construction?

field services

One of the most extensively used heavy-duty machines for road construction and maintenance is the grader. Also known as the road grader, these machines are used to create broad, flat surfaces. In other words, it can be used to spread material and flatten it. As you might have guessed, this is incredibly important for road construction, as the flatter the spread is, the smoother and more durable the road becomes.

Today, we want to delve deeper into motor graders, highlighting exactly why they are so important for road construction:

Why Grade Roads?

For road construction, motor graders are the most efficient way to create safer and smoother roads. The idea here is to remove large rocks and even out areas. Further, by grading the road, you can create a lighter layer of asphalt over the existing layer of asphalt. As the layer of material that is newly laid down is lighter, it is easier to push into the underlying layers.

As you can imagine, the process of grading the road allows for a smoother and more robust final product.

How do Motor Graders Work?

Road graders are designed for use in large fields. Rather than performing the work of grading the road, they are used to prepare the road for maintenance. Typically, they are used for clearing sloped areas, creating building pads, creating ditches, etc. While you could theoretically use other heavy-duty machinery to perform these tasks, these machines are much larger and offer much more power.

As far as their design goes, graders are similar to tractors. They are large, powerful machines that can tackle almost any type of terrain.

Why Are Graders Important in Road Construction?

By creating a perfect surface, you can lay down an asphalt road that is not only smooth but that has the proper drainage. With proper drainage, the road can cope with any weather. Additionally, you’ll be able to lay down the asphalt in much fewer layers than you would if you didn’t grade the road beforehand. This makes the road not only cheaper to construct but much safer.

Another significant benefit of grading roads is that you can lay down a lighter layer of asphalt, which makes the road easier to push into the older layers. As the road will be used for vehicles, this is extremely important. It is also imperative that your road can withstand the weight of the vehicles that will be driving on it. Having a properly graded road will not only make it safe to drive on, but it will last much longer.

Conclusion

As you can see, graders are a vital part of road construction and maintenance. Without them, we would not be able to create the smooth and even surfaces we need for safe and reliable roads. While there are different types and sizes of motor graders, they all serve the same purpose. By creating a solid and even surface, we can lay down a new layer of asphalt which makes the road both safer and more durable. And of course, we’re able to do it all by using a single machine.

How to Ensure Your Grader is In Good Condition

graders for hire in Perth

Graders are a versatile piece of heavy construction equipment used in various on-site grading tasks. It’s primarily used to level the ground after the pitch has been laid, so the operator must be well-trained and knowledgeable of its multiple controls.

Here are some tips and tricks on how you can adequately care for motor graders:

Regular Maintenance Schedule to Reduce Breakdowns

The road grader should undergo regular maintenance to ensure that it’s in good working condition. It should have regular oil changes, an inspection of air filters, cylinders, air-compressor, fuel lines, cab, engines, hydraulic systems, and so on.

If possible, you should also have it inspected by an expert to determine if other parts might need replacement.

Drive at a Safe Speed

Before driving your motor grader, make sure the speed is safe for your rig. If you’re planning on doing some intricate grading tasks, you should drive at a slower pace and be extra careful about your manoeuvring. Always remember that safety should always be number one.

Keep Your Tyres in Good Condition

These vehicles have tyres that need to be maintained and kept in good condition, just like a car. Check the tyre pressure and tread of the tyres regularly so you can fix any possible leaks or cracks.

Keep Your Motor Grader Clean

A road grader needs to be kept clean. Erase dirt marks on the vehicle using a grease-cutting solvent. This way, you can keep it in tip-top shape.

Keep an Eye on the Tyre Pressure

Consistently having the correct tyre pressure of your motor grader can save you from getting into some serious trouble. That’s why it’s essential to check the tyre pressure regularly. You should be able to feel it out if the tyre is too hard or too soft.

It’s also important to note that the machine shouldn’t be used if any leak-related problems are present.

Keep the Safety Mechanism in Good Condition

The safety mechanism is called a rollover protection structure (ROPS). It’s a safety cage uniquely designed for motor graders. The structure should be in good condition to avoid getting damaged when the equipment is being operated.

How to Avoid Common Mistakes When Operating a Motor Grader

Like other heavy construction machines, graders are very powerful and can cause injuries to their operators if not appropriately handled. You must use the right safety gear and operate it safely, so you don’t get injured or cause accidents.

Here are some tips on how you can safely operate your grader:

Stay Alert to Avoid Accidents

The operator of the motor grader should always be alert to avoid accidents. If you’re planning to do intricate grading tasks, then you should be extra careful about your safety.

Lockout or Tagout Any Potentially Dangerous Part

If any parts in your grader can cause injuries to you or any other person, you should lock them out or tag them out to avoid any accidents.

Conclusion

Graders are very powerful and versatile pieces of equipment that can help you in many ways in building and grading.

It’s a powerful machine that can help you level the ground quickly and efficiently, and it’s important to know how to use it to get the most out of it. Consider these tips when operating your grader, and you’ll be good to go.

Understanding the Importance of Road Seals in Australia

hire equipment

In Australia and New Zealand, road seals are an integral part of the road infrastructure. Much of Australia is sparsely inhabited, with significant gaps between population centres. Developing outstanding skills in low-cost road construction and maintenance techniques has been necessary to provide a network of sealed roads. In New Zealand, a limited population base has fuelled the demand for low-cost road construction.

The Importance of Road Sealing in Australia’s Road System

The Australian road network spans 810,000 kilometres, with 330000 kilometres paved with sprayed sealants, concrete, or asphalt. As a result, in many rural locations, sprayed sealants are the preferred method of the surface.

Sprayed seal regions account for 70% of all paved roads in this regard. Sprayed seals are maintained in place by combining binders and aggregate, allowing them to cling to the underlying base and binder, rising and filling the space between the aggregates.

1. Minimises Wear and Tear on Vehicles

Uneven, broken, or pothole-filled roads pose a significant danger to drivers and pedestrians alike.

It’s not always possible to drive around a pothole, and if you ride or drive over one by accident, your tyres are very likely to sustain damage. This is a particular issue for people on motorbikes because it can cause them to tumble off their motorbikes and into oncoming traffic.

Driving over potholes repeatedly can wear down the suspension and produce uneven wear in cars, while pedestrians might trip and fall on uneven portions of the road.

2. Makes Travel Smoother and More Comfortable

Tyres have the best grip on a sealed road surface. When a vehicle is on the road, especially at high speeds, it will be easier to stop and direct the car back onto the road if the vehicle’s tyres can grip the adequately-sealed shoulder surface.

3. Improves the Appearance of the Road

Uneven and damaged roads appear unsightly, and they make road users insecure about the surface’s stability. When damage is left unrepaired, the area can become unpleasant for road users and appear unkempt, whether on a busy road, a residential street, or outside retail stores. Nobody wants to look out their windows and see a rocky road, much less drive on it!

The Road Sealing Process

  1. Before sealing, road cracks are mended with sealants to prepare the road surface.
  2. The road surface is subsequently sprayed with a mixture of asphalt and water. The water in this mixture evaporates almost instantly.
  3. A layer of gravel is laid over the area immediately after spraying the asphalt-water mixture.
  4. With rollers, the gravel is compressed and embedded into the asphalt. Sand is sometimes used to help in the consolidation and curing process. Some pebbles will not become incorporated in the asphalt despite the use of high-pressure rollers.
  5. While the water evaporates, the surface is left to cure for up to two days. The process speeds up during the summer, where the weather is hot and dry, so contractors prefer to work during the summer months. During the curing process, traffic can travel over this surface at reduced speeds.
  6. Finally, any loose gravel is scraped off the seal-coated surface. This requires multiple sweeps by a machine.

 

Conclusion

There’s no arguing that Australia’s road infrastructure requires continuous repair and improvements. Thankfully, road sealing can significantly improve and revitalise the functionality of our roadways.

Why Hire a Water Truck for Your Next Mining Project

water truck hire in perth

Everything on this planet is constantly evolving. While we’re aware of the digital advancements we’ve recently incorporated into our lives, there are a plethora of industries that are constantly experiencing innovation as well.

When it comes to construction and mining, many think that these businesses are stuck in traditional ways. While some traditional techniques are still being carried out, many companies are incorporating new tools and knowledge to help elevate their business’s performance and operations. One shift that’s being integrated into the construction and mining industries is the use of water trucks.

Water trucks are often used to collect and disperse water, depending on the job. This is because they’re equipped with various tools that allow them to get water from a distance and spray them in different directions.

However, they’ve come a long way from just getting water. With new technology, water tanks can also suppress dust and have been widely used in mining and construction projects. Seeing as more industries are getting water tanks for the job, let’s dig deeper into water truck hire and how it can help your business.

What are Water Trucks For?

In a construction or mining project setting, water carts are used as soil compactors, dust suppressants, and environmental rehabilitation. Seeing as water trucks have more uses now, there has been a boom in water truck hires across the country.

When you’re going through a construction project, there’s a high chance that potential contaminants can turn into dusk and potentially pose a health risk to people in the area. This is particularly dangerous because air quality is not entirely visible, so you may not know that it’s already affecting your body. For this reason, contractors use water carts to help suppress dust onsite.

Soil compaction is another purpose of water trucks. During road construction, dust and soil need to be compacted to ensure a high-quality road and eliminate premature deterioration. The water truck works by constantly spraying the road to help it stay bound together.

How are Water Tanks Designed?

The way contractors and equipment operators get and apply water may impact overall operations. Although water tanks were primarily designed to get water, new tech has made them efficient for dust control as well.

Traditionally, round water tanks were the most common design. But these old designs raise the water’s centre of gravity, making the tank smaller than the actual truck, making it less stable and unsafe for long-haul roads. Operators don’t fill the tank to fight this instability, but this can be detrimental to operations since it increases downtime and fuel consumption due to having to refill from a water source.

However, water tanks with square corners can help minimize this issue and they also have a larger capacity, which enhances the overall stability of the truck. This allows operators to drive longer roads and have more water, ensuring a reduced consumption of gas.

The Bottom Line: Work with a Water Truck Hire You Can Trust

Seeing as water trucks have more uses and can be an efficient tool for your construction or mining project, if you’re thinking of getting a water truck hire, it’s worth getting one from a company you can trust. This way, you can rest well knowing you’re operating high-quality machinery and equipment that could help boost your project’s overall performance and output.

Which Properties Make Bitumen Great for Roads

construction service for hire

Bitumen is often used in road construction thanks to its advantages over most pavement construction materials. Bitumen has unique properties built in from its manufacture, which are widely beneficial to road construction.

Here are the reasons why bitumen has significant application in constructing flexible pavements:

1. It is Versatile

Bitumen’s physical and rheological properties are factors in load level, temperature, and duration of loading. Since bitumen is a thermoplastic and viscoelastic material, these dependencies allow constructors to assess and consider the traffic on the road so that the suitable bitumen mix properties are used based on the calculated stress levels.

Moreover, this versatility allows constructors to base the bitumen mix on the road traffic and other factors. As a result, they can produce a wide variety of mixes based on road application.

2. It Is Economical

Bitumen is made from distilling crude oil, which in itself is a composition of hydrocarbons. The main products available are high octane fuels, petrol, diesel and gasoline. When these fuels are refined from crude oil, only the bitumen is left behind.

The bitumen is then further treated to rid it of impurities. As an essential product for society, bitumen as a by-product is set to stay in the market for a long time. It is primarily used as a construction material.

3. It Has a Low Melting Point

Another advantage of bitumen is that it has a low and favourable melting point, allowing it to both surface dressing and wear resistance quickly. Bitumen’s melting point is not so low that it melts easily while still being applied to the pavement.

At the same time, bitumen’s favourable melting point prevents the already cast road from melting and deforming under high temperatures. The material’s aggregate composition helps protect it against the effects of hotter areas.

4. It Has an Adhesive Nature

During the production of bitumen, it is freed from hydrocarbons, eliminating its toxicity. The by-product is refined to a maximum to eliminate organic materials and impurities effectively. Bitumen’s adhesive nature keeps materials in the rod mix bound together under strong bonds, becoming stronger once the mix sets in and is ready for vehicular movement on it.

5. It Can Be Recycled

Besides bitumen having a low and favourable melting point, it can also be melted back to its original state. This is called the asphalt recycling process. The torn-up asphalt pieces can be taken to the plant to undergo recycling and then be reused. If necessary, the old bitumen is mixed with new bitumen and new aggregates to liven up the mix.

6. It Comes in Various Colours

While bitumen is generally black in colour (due to the dense organic material within it), pigments can be added to obtain any colour of your choice. Coloured bitumen is usually more expensive than the standard kind and can be slightly disadvantageous due to the amount of chemical additives and materials needed to make it.

Conclusion

Bitumen has remarkable properties that make it an excellent material for road construction. From its favourable melting point to its chemical compositions it is ideal for exposure to harsh weather conditions, as tested by our Australian summers.

Smooth Rollers Vs. Padfoot Rollers: Which is Better for Your Project?

rent equipment

When you’re looking to rent equipment for your construction project, choosing the right type of machinery to get the correct results is essential. With the plethora of equipment out there, making the right decision can be quite daunting, even when you’re only choosing from two options.

Perhaps you’re here because you’re looking to rent a compaction roller for your job site, but you’re stuck wondering if a padfoot roller or a smooth roller would do the trick. Choosing the best one will depend on your project’s needs, the size of your project, and the ground you need to compact.

If you’re stuck between the two, keep reading. Our team created a quick guide so you can understand the difference between a Smooth and Padfoot roller, allowing you to choose the best one for your construction project.

What is a Roller?

A roller is also known as a vibratory compactor, and its job is to rearrange particles in the soil to decrease voids and enhance its density, providing your surface with load-bearing strength.

Compaction rollers use a circular wheel, known as a drum, to flatten and crush the soil it rolls over. This heavy machinery is most often used for road work. Without them, surfaces would become irregular and more susceptible to wear and tear, which could be dangerous for citizens.

If you’re looking to rent equipment, it pays to know the difference between the two rollers, so you can choose the best one for your job site.

What is a Smooth Roller?

Smooth drum rollers use vibration, static pressure, and impact to compact various surface materials, including sand, gravel, rocks, and asphalt. Many road projects use smooth rollers to flatten and smoothen surfaces successfully, making them one of the most common pieces of equipment for roller hire.

  • Single-Drum Roller: This type of smooth roller uses a steel drum at the front and pneumatic tyres at the back, providing you with quality traction.
  • Double-Drum Roller: Unlike the single-drum roller, this type of roller has a twin-drum located at the front and the back. With less tyres the machine has less traction.

Smooth rollers are best for construction and road work job sites since they compact gravel, asphalt, and soil, turning any surface into driveways, foundations, and pavements. Not to mention, they work best for lengthy road projects.

What is a Padfoot Roller?

Padfoot rollers generate static pressure, impact, and vibration, similar to smooth rollers while generating manipulative force. Because of this, you get uniform compaction in the entire process. Also called sheeps- foot rollers, it uses tapered pads to penetrate and compact the soil to build its strength.

Padfoot rollers are best for projects where you need to compact soil at greater depths. Additionally, this roller type is best if you need to fill trenches in a narrow space since it gives you maneuverability.

The Bottom Line: Knowing What Type of Roller Works for Your Project Can Give You the Results You Need

Seeing as it can be confusing to choose which type of roller you should choose, it’s best to work with credible, professional roller hire companies to ensure you get the best option for your project. Knowing which roller to use will ensure your project is successful, allowing you to get the desired results.

How Can KEE Group Help You?

If you’re looking to rent equipment, it’s best to reach out to a company that you know would give you exactly what you need—that’s where we come in.

KEE Group offers dry hire and fully wet hire, such as rollers, excavators, skid steers, graders, loaders, semi-tippers, low loaders, and more. Even if you have multiple requirements, KEE Group is the one solution you need.
