Does Asphalt Affect the Colorado Environment?

Asphalt has been used for centuries as a paving material. It is durable and weather-resistant. Asphalt in Colorado is used to create a variety of surfaces. But what are the environmental effects of using asphalt? Does it affect air quality? Water resources? How does the use of asphalt in Colorado impact city living? This blog post will take a closer look at asphalt and its effect on the Colorado environment.

The Asphalt Creation Process

Asphalt consists of two main ingredients: rock and bitumen. Rock is the foundation of asphalt pavement. It makes up 85-95% of asphalt pavement by weight and provides structural support for the pavement. The asphalt creation process begins with mining or quarrying rock. The rock is then transported to an asphalt plant, where it is crushed and

mixed with bitumen. Bitumen is a black or dark brown viscous material that binds the asphalt pavement together. It is made up of asphalt cement, a by-product of crude oil refining, and aggregate, a mixture of sand, gravel, and crushed stone.

The asphalt pavement is then placed on a road surface and compacted.

Is Asphalt Reusable?

Asphalt is a sustainable material that can be reused and recycled. It is the most recycled material in the United States. Asphalt companies in Colorado are committed to recycling asphalt pavement (RAP) and milling, which reduces waste and conserves resources.

When asphalt is removed from a road surface, it is crushed into smaller pieces and used as a base for new asphalt pavements. This process is called milling. Milling asphalt can be used to create various surfaces, such as:

  • A temporary road surface while permanent repairs are being made
  • A stable foundation for asphalt paving
  • A drainage ditch lining
  • A material to fill potholes

Asphalt companies in Colorado are also committed to using recycled asphalt shingles (RAS) in asphalt pavements. RAS is a sustainable material that can be used as an additive to hot mix asphalt (HMA). Adding RAS to HMA increases the pavement’s resistance to cracking and rutting and extends the pavement’s life. Asphalt companies in Colorado use RAS in the asphalt pavement to create a more sustainable product.

Asphalt’s Effect On Air, Water, And City Living

Air

While asphalt pavement is not a significant source of air pollution, asphalt production and asphalt paving can release emissions into the air. These emissions include: 

  1. Carbon monoxide
  2. Nitrogen oxides
  3. Particulate matter
  4. Volatile organic compounds

Water

Asphalt production and asphalt paving can also affect water resources. The asphalt creation process uses a significant amount of water, and asphalt pavement itself can contaminate stormwater runoff if not maintained correctly.

City Living

Asphalt pavement can also impact city living as it is a significant source of noise pollution in cities. In addition, asphalt pavement can be a trip hazard, especially for pedestrians and cyclists.

In conclusion, asphalt pavement can impact the environment, but any asphalt company in Colorado is going to be part of the effort toward working to reduce the environmental impact of their products. They are exploring new methods of production that use recycled materials and are developing ways to reuse and recycle asphalt products. These efforts will help reduce waste produced by asphalt companies and contribute to a cleaner environment.

How Does Asphalt Recycling Work?

While you might recycle aluminum cans or plastic bottles at home, many construction companies rely on asphalt paving companies for recycled asphalt. The main material in asphalt, bitumen, tops the global list of most frequently recycled items.

The petroleum product asphalt provides structural strength, can withstand low and high temperatures, plus it can bind together with other materials. Constantly required in the construction of buildings, roads, sidewalks, pools, patios, and much more, this prized substance can also harm the environment to produce. In the US alone, in 2019, manufacturers produced more than 420 million tons of asphalt.

Asphalt paving companies don’t have to use new asphalt though. They can turn to asphalt recycling to reclaim already used asphalt. This reduces its environmental impact. Once recycled, it becomes shingles, waterproofing, or paving products.

Let’s explore how manufacturers mill asphalt, then recycle it, and how it gets used in its most common form – paving.

Asphalt Milling

Asphalt begins the manufacturing process as crude oil. First heated to distill it, the manufacturer then transfers the oil to an extraction container where it removes volatile components called fractions. The heavy deposit leftover – topped crude becomes asphalt after three more steps.

The manufacturer uses a volatile substance to cut back the asphalt. This creates a malleable substance.

Next, the oil goes through an emulsifying process that makes the substance easier to combine aggregate. In this step, the manufacturer grinds the asphalt into tiny globules measuring less than five microns, then mixes it with water. By adding an emulsifying agent like clay, oil, silicate, or soap, the manufacturer reduces the potential for the asphalt and water to separate.

In the final step of making commercial asphalt, the manufacturer pulverizes it to powdered form and sieves it to create granules of a uniform size.

Asphalt Recycling

Asphalt recycling offers a cost-efficient and green method of obtaining this widely used construction material. Recycled asphalt provides no less a product than new asphalt. It provides the same durability and versatility.

Recycled asphalt goes through a milling process in which the manufacturer removes the top layer from the surface on which it got used. This might mean removing the top of a parking lot or driveway or shingling from a rooftop.

Transported to an asphalt plant, the reclaimed product goes through sizing and screening, just as it did when originally made. Unlike its original processing cycle though, when recycled the manufacturer can use either a hot or a cold process to start.

Once it has repeated the original milling process, an asphalt paving company can again use it for a new project. Asphalt offers an ideal construction material since it can undergo multiple recycling cycles without harming its durability or quality.

Asphalt Paving

In some cases, recycled asphalt provides advantages that virgin asphalt cannot. It can contain mineral fillers that increase its strength. It costs less and demands less labor. With respect to its appearance and performance, it offers increased permeability and varying shades of gray. Virgin asphalt comes in black only.

Try Recycled Asphalt

The demand for asphalt continues to grow – about three percent each year. Turn to the $7.1 billion asphalt recovery market for your construction needs. It offers a real money saver for asphalt paving companies.

Keeping Up With Curb Appeal: The Top 5 Driveway Maintenance Tips You Need to Know

Whether you have bricks, pavers, concrete or an asphalt driveway, keeping it in good shape is the biggest factor in how long the surface will effectively serve you. Upkeep is also essential to ensuring that they maintain their appearance and add value to the home. Check out these top tips for maintaining the most common driveway materials.

1. Stay Diligent with Seal Coating

Driveway maintenance will be eased with routing seal coating of the installation’s surface. This is a good move for most kinds of solid-surface driveways, and is a must-do for concrete and asphalt materials that can stain and deteriorate with excessive sun and moisture exposure.

However, an asphalt driveway will need around 90 days to cure before being sealed. Most surfaces will need to be resealed about every two years to extend their lifespan and keep them looking attractive. This task is often best left to professionals, as it takes special tools and can be time-consuming for the typical homeowner.

2. Clean Up Stains Quickly

Routine seal coating can help prevent stains from oil, gas and other fluids that can penetrate bricks, pavers, concrete and asphalt driveways. Yet, it’s best to immediately clean up any such spills to keep stains at bay, which is likely to detract from the beauty of the home. Consider regular pressure washing to retain an ultra-clean look throughout the year.

3. Don’t Let Plants Take Over Driveway Surfaces

While green foliage is desirable in landscaping, plants and weeds can be a true menace to driveways. They can penetrate through to the surface by way of small cracks, which can actually widen them over time. Experts recommend filling in any cracks quickly and aggressively.

To prevent grass from taking over the edges of driveways, invest in some type of trim, edging or river rocks to place along the sides. In addition to keeping grass where it belongs, this addition can become a key visual element of your hardscaping design.

4. Perform a Driveway Inspection After Winter or Heavy Freezes

Should you reside in an area that sees freezing temperatures or seasonal snowfalls, the driveway will experience freeze-thaw cycles. Unfortunately, this can be a primary cause of driveway damage and is a particular issue with an asphalt driveway that can easily shift.

Be sure to do a visual inspection after deep freezes or heavy snow to check for cracks, potholes, or any signs of crumbling materials. Be prepared to take care of any necessary repairs right away. Ignoring deterioration will only allow the problem to worsen and spread to other areas of the driveway.

5. Invest in a Driveway Professional

While it’s possible to do a good portion of driveway maintenance and basic repairs as DIY projects, bigger jobs might be best left to professionals. In cases of tough stains or large installations, an experienced technician can make magic happen with greater ease and in less time. Having a local contractor in place ensures fast repairs and regularly scheduled seal coating and cleaning.

Don’t Underestimate the Talents of a Pro

As you can see, the driveway is a large part of a home’s exterior features, and will be seen by neighbors and passersby on a regular basis. Don’t be the neighbor who neglects their driveway and drives down the overall curb appeal on your street. Invest in driveway maintenance!

Is a Concrete Driveway the Best Choice for Your Home?

Has your driveway seen better days? Cracks, potholes, and drainage issues are all tell-tale signs that a new driveway install may be in your immediate future.

If you’re ready to replace your driveway, you have many options, including having a concrete driveway or a cement driveway installed. Keep reading to learn about the pros and cons of installing a concrete vs. a cement driveway.

The Differences Between Concrete and Cement Driveways

Concrete and cement are often used interchangeably because they look similar; however, they are not the same. Very few things are constructed with cement alone.

Cement is an ingredient in concrete. Along with cement, concrete is also manufactured with water and aggregates including gravel, stone, and sand, which make up about 75% of concrete. Cement, meanwhile, is made from a mixture of silicon, calcium, iron, and aluminum, which are then heated up to a very high temperature before being ground into a fine powder we know as cement. It is then often used as a component of concrete.

Using cement alone is more suitable for smaller projects such as grout or to repair damaged concrete. Most experts don’t recommend using just cement to construct a driveway because it is less durable than concrete and won’t last as long.

Using Concrete to Construct a Driveway

Concrete is one of the most popular and durable materials in the world. It’s used to construct homes, commercial buildings, driveways, columns, and foundations.

Some of the benefits of choosing a concrete driveway over cement, asphalt, or gravel include:

Durable and Long Lasting

Well-maintained concrete driveways can last 30 years or more. Ensure you hire a reputable concrete company to install your driveway as proper installation plays an important role in the durability and lifespan of your driveway. Typically constructed with separate square slabs, concrete driveways are durable enough to handle heavy trucks, RVs, and boats. Concrete driveways often last 50% or longer than asphalt surfaces.

Low Maintenance

Concrete driveways are incredibly easy to maintain. They typically require only regular sweepings or power washes. A concrete sealer should be applied once a year, especially in colder climates that experience frequent freeze-thaw cycles.

Cost-effective

Although concrete driveways are more expensive to construct than other surfaces, they’re most cost-effective in the long run because of reduced maintenance costs, fewer repairs, and a longer life expectancy.

Increased Home Value

Concrete driveways can help increase your home’s value. Not only do many people think concrete is more aesthetically pleasing than other surfaces, but potential homebuyers may be more likely to buy your house knowing the surface requires little maintenance and can last for 30 or more years before a replacement driveway is needed.

Environmentally Friendly

Concrete is a recyclable material, which makes it environmentally friendly. It also requires reduced energy than other materials because it doesn’t need to be repaired, resurfaced, and it lasts longer.

The Cons of Installing a Concrete Driveway

Overall, there are very few cons to installing a concrete driveway. If you’re looking for a cheaper alternative to a concrete driveway due to budgetary constraints, then it may be more cost-effective in the short term to install an asphalt driveway.

Although concrete requires minimal maintenance, it does need to be sealed once a year to ensure the durability of the surface. Fluids or oil stains from cars can be very difficult to remove once they seep into the surface.

7 Pavement Preservation Treatments for Your Asphalt Surface

Constructing an asphalt surface such as a driveway, parking lot, or basketball court is a significant financial investment, so it only makes sense to protect it. That means regular maintenance should be performed to preserve the integrity of your asphalt surface and extend its lifespan.

We’re here to help you get the most out of your asphalt surface. In this article, we’ll discuss 7 pavement preservation treatments for your asphalt surface.

1. Routine Maintenance

Routine maintenance is necessary to prevent damage and staining. Fuel and oil from vehicles, as well as leaves and debris, can lead to permanent stains on asphalt surfaces. Oil and fuel spills can also seep into the pavement, leading to cracking and other damage such as potholes. Rock and gravel can also harm the surface when they’re run over by cars.

Asphalt surfaces should be swept frequently, especially after storms, to remove dirt and debris. Car oil and fuel, meanwhile, should be cleaned immediately using a long-handled brush and a mixture of water and either powdered detergent, dish soap, or baking soda.

2. Sealcoating

Sealcoating is another great way to preserve the integrity of your driveway or asphalt surface and make it “pop” again. Many people wait too long to sealcoat surfaces, which can lead to premature wear and a faded, gray color. Consider sealcoating every two years.

The benefits include:

  • Prolonging the surface’s lifespan.
  • Preventing water from seeping beneath the surface and causing cracks and other damage.
  • Restoring the black color.
  • Protecting the surface from harmful UV rays.

3. Crack Sealing

Cracks are bound to sprout up on asphalt surfaces over time, and if you wait too long to fix them with a crack filling or crack sealing, they’ll keep spreading. Although this service can be done throughout the year, one of the best times to contact asphalt companies is after winter. The constant freeze-thaw cycle can wreak havoc on asphalt surfaces.

4. Patching

Like cracks, potholes are also a common enemy of asphalt and can form when water seeps into cracks, freezes, and expands. Potholes are not only an eyesore, but they can lead to trips and falls, and vehicle damage. Patching these areas is an extremely cost-effective solution to improving the appearance and safety of your asphalt surfaces, as well as extending their lifespan.

5. Overlays

Asphalt overlaying is a method of applying about two inches of asphalt over areas of the existing base layer that have deteriorated due to significant potholes, cracks, or uneven surfaces. An overlay can extend the life of your asphalt surface by as much as 15 years depending on its age.

6. Slurry Sealing

Slurry sealing is a type of sealcoating used to protect asphalt and add value to asphalt surfaces. While normal sealcoating uses liquid asphalt, slurry sealing contains water, aggregates, and asphalt emulsion. Slurry sealing is commonly applied every five to seven years on roads that have received severe deterioration due to traffic.

7. Microsurfacing

Microsurfacing is an asphalt maintenance technique that can extend the life of blacktop roadways by an average of five to seven years. It’s a third less expensive than repaving and is commonly used by local governments for roads. Microsurfacing is the process of using a mixture of aggregate, water, and asphalt emulsion and adding it to an existing surface. Microsurfacing doesn’t rely on water evaporation in the asphalt emulsion, and, instead, uses chemical additives that can harden quicker.
