What are the properties of Asphalt

When considering asphalt concrete mixtures, each mixture needs specific properties to meet recommended safety guidelines. Whether for blacktop paving or other construction projects, reach the required mix properties in stability, durability, flexibility, fatigue resistance, skid resistance, impermeability, and workability. Read the specifics below.

The Importance of Stability

Stable paving will remain smooth and not alter in shape regardless of loading and stress. This is essential for blacktop paving. A balance between internal friction and cohesion increases stability. This will help maintain shape under heavy traffic.

Maintaining Durability and Impermeability

Pavement withstands considerably stressed due to traffic, weather, and moisture. To maintain durability, use maximum binder content and a denser gradation of stripping resistant aggregate. This helps reduce the passage of moisture, water, and air through the pavement.

Workability and Flexibility Are Key

The more workable the mixture is, the easier it is to place and shape. Ensure stability to avoid issues with workability. If a mix is too easy to work, then the resultant mixture can be unstable. This “tender mix” might have too much moisture, not enough mineral filler, or too much sand. Flexibility determines if the pavement will resist cracking. All asphalt pavement needs flexibility to avoid cracking, potholes, and other damage. 

Fatigue Resistance

Constant heavy traffic leads to bending in the pavement. If the pavement has not been mixed properly or exhibits fatigue, cracking results. Aging and poor mixing contribute to poor fatigue resistance.

The Importance of Skid Resistance

For high traffic areas, skid resistance helps tired grip the surface and avoid slipping and skidding. Especially important in areas with high precipitation, skid resistance prevents accidents and injury. Avoid smooth surfaces. Rough surfaces have more skid resistance.

Follow all mix requirements to maintain these key desirable properties. If you have questions about paving, asphalt, and concrete, feel free to contact our experienced professionals today. We are ready to help you with your project.

How Long Does a Paved Road Last?

How long will your paved road or driveway last? Exceptional installation is the key factor in determined the longevity of a road. What are some best practices for asphalt or concrete paving of roads? What materials last longest?

Regular Maintenance

Whether using asphalt or concrete, consistent maintenance will make the biggest difference. Paving of the roads involves more than laying down asphalt or concrete. When the roads begin to crack or the winter damages structural integrity, contact a paving professional to seal and repair the road.

Winters are especially brutal to roads. Snow and ice melt into small cracks and holes. As the temperatures drop, the water freezes. This expansion causes the small cracks to grow larger, sometimes into large dangerous potholes. If possible, have a professional seal the road before the winter season strikes. Once winter is over, begin to repair any damage.

Concrete vs. Asphalt Paving

If you maintain the road concrete can last as long as three decades. Asphalt will last closer to fifteen to twenty years. In both cases, though, be sure that you seal and repair every year. You might find that over time the driveway will lose is aesthetic appeal. You might choose to replace the entire road if it is beyond repair.

Hydroblasting

Sometimes you can grind down the topmost layer of the concrete, leaving behind stronger concrete. However, another option is hydroblasting. Hydroblasting will lengthen the life of your concrete road. A silica fume concrete overlay will be placed over the road after the contractor identifies any weak areas. A road that has been hydroblasted may last for fifty years.

Follow a regular maintenance schedule to ensure the longest lifespan for your road. Call us today with any questions.

Top 4 Pros and Cons of Asphalt in 2019

Asphalt remains a popular driveway and parking lot option for many homeowners and business owners. Properly installed asphalt can last for many years, especially with regular asphalt driveway sealing and maintenance. What are the biggest pros and cons of asphalt paving for 2019?

Relatively Low Maintenance

Asphalt paving is a clear aesthetically pleasing choice. To keep your asphalt driveway or parking lot looking pristine, clean it at least twice a year. Regularly maintain the driveway with professional asphalt driveway sealing. Deal with any cracks, potholes, or damage immediately. You should seal-coat the asphalt every two to five years. This will ensure that the surface remains strong and water-resistant. Contact our professionals today to learn how to maintain and improve your driveway.

How Long Does Asphalt Last?

While concrete driveways last about thirty years, a well-maintained asphalt driveway lasts about twenty years. However, many homeowners and business owners prefer the look of the asphalt over aged concrete. Regular maintenance will help keep the curb appeal of your home.

Costs are Lower

The cost of an asphalt driveway is about half the cost of concrete. It can cost around five dollars per foot, depending on the installer and the materials. Keep in mind that there may be extra costs depending on how much space you need to pave and if there are features, like landscaping, that need to be considered.

Weather

Like many other materials, asphalt takes a beating in colder weather. The snow and ice melt into the cracks of the driveway. When the liquid freezes, it expands. This can cause potholes, deep cracks, and structural damage. It is recommended that you repair your driveway before the winter sets. If you are not sure how to repair your driveway and winterize it, please call us today. Our seasoned professionals can help you.

How Strong is Asphalt?

Homeowners choose asphalt for their driveways because of its strength, cost, and durability. Maintenance, driveway sealing, and installation are significantly more affordable with asphalt. Both concrete and asphalt pave driveways, roads, and parking lots. Both have different benefits and challenges. How durable is an asphalt driveway?

Maintaining Asphalt

Every material has its own unique challenges. Regular maintenance and repair are necessary with asphalt. Asphalt is prone to discoloration and needs driveway sealing every couple of years. Every five to ten years the homeowner needs to coat the entire driveway. Part of this is due to its weaker structure. While affordable, most asphalt driveways last about fifteen to twenty years. Homeowners need to take this into account when determining if they want to purchase asphalt.

Homes in extreme climates will have to maintain their asphalt driveways on a more regular basis. The material becomes soft under high temperatures, causing cracking. Thicker asphalt with a thicker profile will prevent some of the more common issues. Sealing cracks before precipitation settle also lengthen the lifespan of your driveway. Hiring a trusted paving company to install your asphalt driveway greatly minimizes long-term cost.

Aesthetics

Many homeowners like the look of blacktop. Some find it more aesthetically pleasing than plain concrete, gravel driveways, crushed stone, or crushed basalt. Asphalt provides more curb appeal than these options. Other driveway options like stamped or colored concrete, brick, or cobblestone have more options for customization at an additional cost.

What is the Difference Between Asphalt and Bitumen?

Before starting on your next driveway repair or replacement, research each aspect of the paving process. Know what is asphalt made of. This includes also knowing the difference between asphalt, bitumen, and other key terms. While asphalt and bitumen are both used in pavement construction, they each have unique uses and properties.

Bitumen Basics

The liquid binder that holds together asphalt is called bitumen, or mineral tar. Bitumen comes from the partial distillation of crude petroleum. What is asphalt made of? A manufacturing plant heats, dries, and mixes bitumen, aggregate, and sand. A paving machine also applies the mix.

However, people confuse bitumen and asphalt. For example, some roads and driveways use a bitumen seal overlaid with aggregate. But don’t confuse asphalt with tar – a very thick liquid derived from coal that has fallen into disuse for environmental reasons. There are several different types of bitumen like cutback bitumen, plastic bitumen, and also straight run bitumen.

What is Asphalt?

Asphalt is sticky and black, and incredibly thick. Asphalt solidifies at lower temperatures. At high temperatures, the asphalt liquefies. The mixture consists of lime, silica, alumina, and asphaltic bitumen. There are two different types of asphalt: residual and natural. PAving companies obtain natural asphalt from lakes and rocks. On the other hand, residual asphalt is obtained by distilling crude petroleum with an asphaltic base.

Pavers categorize four different types of asphalt: mastic asphalt, cutback asphalt, asphalt cement, and asphalt emulsion. Asphalt emulsion is used in colder conditions. Companies use cutback asphalt for manufacturing bituminous paint. Roofing, waterproofing, and flooring projects can use asphalt cement.

3 Tips About Asphalt Reconstruction

When considering asphalt construction, there are many important professional tips that will save you time and money. Some of these tips are simple, like using driveway sealer to add protection to your driveway or avoiding bad weather during construction. Let’s review some of the most important professional tips when reconstructing an asphalt driveway.

The Importance of Protection and Maintenance

Your driveway adds considerable curb appeal and safety to your home. From protecting your vehicle’s tires from debris to providing a safe place for your family and visitors to walk, it is important that you take all the maintenance steps necessary to lengthen the life of your driveway. This helps minimize the overall cost of full reconstruction. For example, using a driveway sealer on your driveway will add an extra layer of protection against cracking and potholes. While replacing an entire driveway is not always preventable, simple steps can add extra protection.

The Road to Smooth Pavement is Laid with a Quality Mat

Before starting work, be sure that you have a professional team help you. The paver should be operating correctly, properly prepared for construction. The paver speed will affect the smoothness of the pavement. Be sure that the crew focuses on the project, especially the mat thickness.

If the paver applies material at the wrong speed, your driveway could end up with ripples and irregular mat depth. This will result in major flaws in your material thickness. The right amount of material needs to be constant. Fortunately, there are automatic feed systems to help monitor the number of materials being laid across the width of the screed. Consistent paving yields the best results.

Consistent Temperature

Monitoring mat temperature is paramount to successful and smooth paving. Compaction needs to be accomplished with enough fluidity to remove excess air. The compactor operator is responsible for maintaining the right temperate during construction. A final step is having a consistent rolling pattern. This will affect the long-term use and stability of your driveway.

Contact your local paver to discuss ways that you can ensure a smooth driveway during asphalt reconstruction.

The Complete Process for Asphalt Pavement Installation

The Complete Process for Asphalt Pavement Installation

You’ve decided on asphalt for your new driveway, sidewalk or parking lot.  You’ve made the call to Epic Paving to schedule an installation.  Everything’s all set – but now what happens?  Just what’s actually involved in installing asphalt?  Here’s a step-by-step guide on what you can expect as your new asphalt is being laid down.

Demolition

The first thing that needs to be done is to remove the existing surface!  If it’s old asphalt, it can often be recycled, making it an environmentally friendly choice.  Otherwise, the asphalt, concrete or old interlocking pavers are torn up with heavy machinery.

Grading

Water drainage is key to ensuring a long-lasting asphalt surface.  With that in mind, your contractor will grade and slope the surface to ensure that water runs off properly, using motor graders to get the perfect slope.

Subbase

The subbase provides a stable support for your new asphalt, and protects it from dangerous freeze-and-thaw cycles in Toronto’s harsh winter weather.  This is installed after grading, with the contractor making sure that it’s properly compacted to provide years of durability.

Binder

The binder layer is coarser grade of asphalt, with larger stones.  This is added to increase the strength and durability of your new asphalt.  Without it, your asphalt top would likely crack or break under the constant pressure of cars and other heavy machinery.   The binder layer helps fight against breaking and cracking, keeping your asphalt strong for years to come.

Top Layer

Finally, the top layer is added.  This is the finer layer that provides a great aesthetic quality and ensures a smoother, more comfortable surface to your new asphalt installation.  It’s made up of smaller aggregate than the binder layer, as well as sand and oil.  It also produces that deep black color that gives new asphalt its trademark shiny finished surface.

Transitions

After the asphalt has been laid down, the transition from the new asphalt to preexisting driveways, roadways or parking lots need to be smoothed – otherwise, you get large, uncomfortable bumps.  It takes special attention to make sure the water run-off is appropriate in these areas; if not done properly, they can be common trouble points for water pooling.

Final Roll

When everything is laid down, from the subbase to the very top layer, it’s time for the final smoothing and compacting.  A roller truck is used to compact and smooth the surface, making sure that no bumps of aggregate or stone remain in your new surface.

When you trust Epic Paving with your asphalt installation, you can rest assured that you’re getting a surface that will provide years of durability and functionality.
