Is it Ever Too Hot or Too Cold to Pour Asphalt?

Summer is paving season – all over the country, more roads, driveways and parking lots are paved during the summer than any other season. The reason is the hot-mix asphalt is easier to install and create compaction when the air and ground is warmer. If you have a paving project you are planning, weather is a factor. But you may wonder whether it is ever too hot or too cold to pour asphalt?

Cold Weather Can Impact Asphalt

The basic rule is that asphalt is best poured when the temperature of the air is at least 50 degrees and rising. This is due to the affect the cold air can have on the hot asphalt, cooling it too quickly can make it difficult to create the right compaction. The ground temperature is even more important – if it is still too cold even on a warm spring day, it can impact the quality of the asphalt.

Hot Weather is Perfect for Asphalt Paving

Hot summer days make it easier for paving with asphalt. The air helps slow the cooling process and the ground is well above the needed temperature for quality compaction of the asphalt. While asphalt can be poured regardless of how hot the air temperature gets, extreme heat can be dangerous for the workers doing the paving.

Seasonal Asphalt Installation

In mild regions, asphalt can easily be completed year-round with great results. Those who live in areas with cold winters should plan their paving projects for late spring, summer and early fall for the best chance of success. Striving for temperatures between 70-90 degrees in dry weather is ideal time to schedule your asphalt paving project.

Benefits of an Asphalt Driveway

There are many options when it comes to paving your driveway. Pavers, concrete, brick and asphalt are all options, but there are some benefits to choosing asphalt. There is a good reason you see so many asphalt driveways and parking lots – including these benefits.

  • Longevity. When maintained, asphalt driveways can last for twenty or more years. The material can handle heavy weight without cracking like concrete, including large commercial vehicles. If you want a driveway that will last for decades, even with heavy traffic, asphalt is an excellent choice.
  • Easy maintenance. Asphalt is simple to keep clean and easy to maintain. It does not show stains as easily as light pavers or concrete. A quick pressure washing or sweep can make it look beautiful again.
  • Low cost. When it comes to cost, asphalt is one of the most inexpensive materials for paving, especially considering how long it lasts. If you are on a budget, you can add asphalt to your driveway for much less than most other paving materials.
  • Fast installation. Want a new driveway right away? Asphalt cures quickly and can be ready for use in as soon as one day. Pavers can take days just to install and concrete may not be ready for use for a week. Asphalt is the fastest way to pave your driveway and have it ready for almost immediate use.

When it comes to cost-efficient, long-lasting materials for your driveway, it is hard to beat asphalt. It looks beautiful if kept maintained with sealcoating every few years. Talk to your local paving company to learn more about the advantages of using asphalt for your new driveway surface.

Can You Pave Asphalt Over Existing Concrete?

A common question asked of paving contractors is whether asphalt can be paved over existing concrete. While the obvious answer is yes, as existing concrete gives an already hard, flat surface to be overlayed with asphalt. However, there are possible issues asphalt resurfacing over concrete, so it is important to understand what these issues are before you hire a contractor to pave over your concrete driveway or parking lot. 

What Is Under The Concrete

Concrete can be a great base for asphalt, as long as it’s stable and doesn’t begin to move underneath the asphalt. While asphalt is compacted to the surface it’s applied over, concrete is merely poured, then cured in place. If the ground beneath the concrete is unstable, the concrete will eventually begin to move, causing damage to the overhead asphalt. However, if the concrete has been in place for years with no signs of instability, it should be a good base for the new asphalt. 

Expansion Joints

Concrete is jointed, while asphalt is not. These expansion joints in concrete are to allow movement and a crack to form when needed to preserve the concrete. If these cracks occur under asphalt, there is a good chance the asphalt will also have a crack in the same area. However, this is not guaranteed, and it can be remedied by filling cracks as they form. 

So yes, you can pave over an existing concrete driveway or parking lot. In most cases, concrete makes an excellent surface for new asphalt. If you know what to expect, you can look for any cracks or issues and have them fixed before they become a larger problem.

What Is Asphalt Anyway?

We drive on it almost every day, yet what do you really know about asphalt? This tough surface is used on most highways, roads and parking lots, not to mention a great surface for personal driveways. If you are considering using asphalt for an upcoming home or business project, here is a little basic information about how this material is created and applied for many versatile uses. 

Asphalt 101

In most applications, asphalt paving is compromised of four ingredients: aggregate, sand, petroleum and additives. The majority of the composition is sand and aggregate, with only about 10% petroleum and additives. This combination creates a material that is not only durable, but also flexible, allowing it to withstand heavy loads and extreme temperature variations with relative ease. 

To make asphalt, first the aggregate is dried and weighed to get the right consistency and amount. When ready, it is transferred into a silo where sand, liquid petroleum and additives are slowly mixed into the aggregate. The mixture is kept heated until it is ready to be used. 

To lay asphalt, the most important aspect of the project will be the groundwork. The ground must be leveled and treated with an liquid asphalt binder, or tack. This preparation must be performed correctly in order to create an even surface that will last for decades. Once the ground is ready, the asphalt is applied with a professional asphalt paver, using an asphalt roller to compress the asphalt into a smooth surface. 

For both commercial and home use, asphalt is an affordable material that is quick to install and easy to maintain. Seal coating can be added once the asphalt is cured, usually about 4-8 weeks after the initial installation and then every few years, depending on climate and usage.

Understanding Asphalt Pavement

Asphalt, also called backtop or tarmac, is one of the most popular paving products in use today.  It is durable, flexible, and waterproof and provides a long lasting surface that needs relatively little maintenance.  Asphalt is a great choice for a new driveway, parking lot, tennis court, basketball court, running track, cycling or walking path, or similar paving projects.

Choosing a good asphalt paving contractor for any asphalt paving project is important because a poorly installed asphalt surface will deteriorate much quicker than one that was properly installed.  An understanding of asphalt paving will make it easier to discuss your project with contractors. 

Asphalt is made by mixing sand and gravel with heated asphalt cement which binds the sand and gravel together.  The first step in installing asphalt pavement is to remove the topsoil and compact the soil underneath, called the subgrade.  A base of crushed gravel aggregate is installed on top of the supbgrade and covered with a layer of asphalt.

The aggregate base is what provides the support for vehicles or pedestrian traffic.  The main purpose of the asphalt blacktop surface is to provide a smooth surface and to protect the aggregate base from water intrusion which reduces the ability of the aggregate base to provide support.

It is important that the aggregate base is thick enough to support the heaviest loads that will be placed on the pavement.  If the aggregate base is too thin, it will sink under heavy loads and cracks, ruts, and potholes will begin to form in the pavement.  These will allow water into the base causing further deterioration of the pavement.  Be sure to use an experienced asphalt pavement contractor for a durable asphalt pavement project.
