How to Pave With Asphalt
What does asphalt paving mean? Is it something that you should consider or even bother considering?
Asphalt paving has become quite common these days. Many homeowners prefer to pave their driveway instead of using concrete because it is cheaper and easier to install. The downside of asphalt paving is that it takes longer to lay down than concrete. In addition, asphalt pavement requires maintenance such as sealants and repaving every five years.
Paving is the process of laying down concrete or other materials over a road surface to create a smooth finish. The type of material depends on where you live. Some areas require only a thin layer of concrete, while others require several layers. In some places, such as California, drivers pay extra fees for using certain types of pavement.
Asphalt costs vary depending on the project's location, size, and thickness. This can range from $50-$1,500 per square yard (about 2.5 sq m). There are also options for precast pavers, which are easier to install and less expensive than poured concrete.
Asphalt Pavement for Homes and Businesses
There are many different types of asphalt pavement available today. They include:
• Asphalt Shingles - These are made of asphalt shingles, similar to roof tiles. They come in various sizes and colors.
• Concrete Pavers - These are small blocks of concrete that are used to make driveways and walkways.
• Precast Concrete Pavers - Similar to concrete pavers, they have been cast before being installed.
• Retaining Walls - These walls are built around an area to prevent erosion. They may be made of stone, brick, or concrete.
• Tarmac - This mixture of sand, gravel, and bitumen. It is often used for roads and parking lots.
• Turf - This is grass laid down over a compacted soil base.
Asphalt Overlay Can Prevent Drainage Issues
When installing asphalt pavement, it is important to know how to prepare the ground properly. If the ground is too soft, it will absorb water and cause drainage problems. To avoid this problem, you must remove any existing vegetation and topsoil. Then, dig out the subgrade to a depth of about 6 inches (15 cm) below the frost line. Next, add a layer of crushed rock or gravel to provide traction. Finally, apply a layer of sand to help drain the area.
If your home sits near a body of water, you should consider adding a waterproof membrane to the asphalt for proper drainage. A waterproof membrane serves as effective drainage to help prevent moisture from seeping into the ground. It also prevents rainwater from damaging the foundation.
Different Asphalt Types
There are three main types of asphalt:
• Bituminous - This type of asphalt is very common. It is made up of coal tar and natural gas. The asphalt can be either liquid or semi-solid. Liquid bituminous asphalt is poured directly onto the ground. Semi-solid bituminous asphalt is heated until it becomes a liquid. Once it cools, it hardens.
• Crushed Stone - This type of asphalt is similar to crushed stone. It is made up mostly of limestone and clay. It is available in both liquid and semi-solid versions.
• Gravel - This type is made up of small stones. It is available as a liquid or a semi-solid. When applied, it dries quickly and does not require heating.
What is Recycled Asphalt?
Recycled asphalt is made by mixing old asphalt pavement with new asphalt. It is commonly used in road construction projects.
It is important to note that recycled asphalt has different properties than regular asphalt. For example, it tends to crack more easily. It also requires additional maintenance.
A few things to keep in mind when using recycled asphalt include:
• Do not drive over it.
• Avoid driving over it after dark.
• Keep children away from it.
• Wear safety equipment such as work boots, gloves, eye protection, hearing protection, and protective clothing.
• Use caution around moving vehicles.
• Remove debris before applying the material.
Asphalt Paving Methods
Paving methods vary depending on what kind of surface you want to create. There are two basic paving methods:
• Cold Mix - This method uses hot asphalt mixed with aggregate. It is typically used for parking lots, driveways, and other paved surfaces where speed and durability are less important.
• Hot Mix - This method uses cold asphalt mixed with aggregate. Because it is slower to pour, it is often used for roads.
The following sections describe each of these methods in detail.
Cold Mix Asphalt
This method is best suited for parking lots, driveways, and other paved surfaces that do not have high traffic. It is also ideal for low-volume applications.
To install cold mix asphalt, follow these steps:
1. Dig out the subgrade to at least 12 inches (30 cm).
2. Add a layer of crushed rock to provide traction.
3. Apply a layer of sand to improve drainage.
4. Pour the asphalt mixture.
5. Smooth the surface with a roller.
Hot Mix Asphalt
This is the most popular method for creating paved surfaces. It is suitable for all paved surfaces, including roads, highways, and parking lots.
To install hot mix asphalt, follow these simple steps:
1. Excavate the area to be paved.
2. Spread gravel or crushed stone over the base.
3. Lay down the first course of asphalt.
4. Fill any voids with asphalt.
5. Level the top surface.
6. Smooth the surface with an asphalt roller.
7. Seal the surface with a sealer.
8. Drive over the newly installed asphalt.
9. Repeat Steps 3 through 8 until the desired depth is reached.
10. Finish with a final coat of sealer.
11. Wait several days for the sealer to cure completely.
12. Drive over the finished surface.
13. Maintain the surface by sweeping and cleaning spills promptly.
14. If necessary, apply another coat of sealer.
Asphalt Pavement Installation
Many factors can affect the asphalt installation process. These include the type of asphalt being used, the temperature of the surrounding air, the amount of moisture in the soil, and the weather conditions.
If you need help installing your asphalt, you must contact professional asphalt contractors. They will know how to handle the situation safely and efficiently. The contractor should provide a written estimate before starting work, which will give you information about the quality materials needed, the time it takes to complete the project, the process of proper asphalt installation, and any additional costs associated with the job. If you approve the asphalt paving job's final cost, ask the contractor to sign off on the contract, so you know who's responsible if problems arise.
Maintain Your Asphalt Driveway
You may think that once you've poured your driveway, there's no more maintenance required. But this isn't true. You still need to maintain your commercial or residential driveway every year.
Here are some things you can do to keep a long-lasting driveway looking great:
• Sweep up debris regularly.
• Clean spills immediately.
• Remove weeds from around the edges of the driveway.
• Keep grass trimmed back.
• Use a broom to remove dirt and dust from the entire surface.
• Look for cracks in your driveway.
• Repair potholes as soon as they appear.
• Check your water supply pressure.
• Be careful when driving on wet pavement.
• Avoid using your driveway during heavy rainstorms.
• Don't park cars in uneven areas.
• Never drive on loose gravel.
• Remember that your driveway is part of your home's curb appeal and you should maintain the quality of asphalt you have.
What Are The Benefits of Having an Asphalt Surface?
The following sections describe the benefits of asphalt in detail according to asphalt professionals.
Resistance To Cracking and Breaking
Cracks can develop in asphalt because of changes in temperature, humidity, traffic loads, and other factors. When cracks form in your driveway, they can cause damage to vehicles and pedestrians. In addition, cracks can allow water into the ground, causing erosion and flooding.
Asphalt resists cracking and breaking better than concrete. This means that your driveway lasts longer and requires less maintenance.
Increased Safety
Drivers often assume that their tires will be safe on any road. However, roads made of asphalt have special characteristics that make them safer than those made of concrete. For example, asphalt has greater traction than concrete, making it easier to stop and steer. It also provides a smoother ride, reducing the chance of skidding or sliding.
Asphalt is also more durable than concrete. Because it doesn't crack or break easily, it won't crumble under heavy loads like concrete.
Reduced Maintenance Costs
Concrete surfaces require frequent repairs. Repairs can involve replacing damaged portions of the concrete, repairing joints between pieces of concrete, or resurfacing the entire area.
In contrast, asphalt surfaces don't require much maintenance. They're easy to clean and repair. They're also resistant to wear and tear, meaning they last longer.
Faster Construction Time
Because asphalt is lighter than concrete, it can be laid faster. This makes it possible to build larger projects in shorter periods of time.
It's also easier to install. Concrete must first be broken down into small pieces, then mixed. Once the mixture is ready, it needs to be set up for several hours before it can be used.
Asphalt can be installed right after it comes out of the manufacturing process. No mixing or setting up is necessary.
Less Labor Intensity
Asphalt paving is one of the easiest jobs you can hire someone else to do. A skilled asphalt installer can lay a new surface in just a few days.
This saves you money by cutting down on labor costs. You'll also save time because there are fewer steps involved.
Easy-to-Use Equipment
Asphalt paving equipment is designed specifically for this type of work. It's lightweight, so it's easy to move around. It also has low operating costs, which allows you to spend more money on materials.
You can use the same equipment to pave multiple areas at once. This reduces the amount of time needed to complete the project.
Easier Cleanup
When you finish paving a driveway, you can sweep away all the debris without worrying about cleaning up the mess.
If you need to remove some dirt from the surface, you can simply wash off the excess material.
If you want to remove the old pavement completely, you can use an excavator to dig up the old surface. Then you can replace it with fresh asphalt.
Is Asphalt Cheaper Than Concrete?
The cost of installing a layer of asphalt varies depending on how large the job is. The price of asphalt installation depends on the size of the area being paved, its thickness, as well as the number of lanes.
For example, if you're planning to pave a two-lane road, expect to pay $10 per square foot (about $1.25 per square meter). If you're paving a four-lane highway, expect to pay $15 per square foot ($2 per square meter).
However, an asphalt surface is generally less expensive than a concrete driveway. Asphalt is usually cheaper than concrete for smaller jobs.
For example, if you plan to pave a parking lot, you may find that asphalt is slightly more expensive than concrete. On the other hand, if you're paving a sidewalk, you might find that asphalt is significantly more expensive than concrete.
Concrete is typically more expensive than asphalt when considering the total ownership cost. However, asphalt is still a good choice for many homeowners.
