Can You Pave Asphalt in Cold Weather in Michigan City?

It's happened before.

It's happening now.

Someone was so determined to get a driveway paved or a parking lot repaired that they put it off all summer. Then the leaves start to change, it gets colder outside as the days go by, and winter is coming quicker than anyone expected.

The natural question is asked.

"Is it too late to pave?"

Unfortunately, the answer is not as easy as simply "yes" or "no".

While asphalt can certainly be installed in cooler weather, it's important to understand that temperature can be a major factor in not only laying but also compacting the pavement itself.

In Michigan City and LaPorte County, this means that the timing for paving can sometimes come down to the conditions on a specific day.

Some fall days will be ideal for paving.

Some will not.

The key is to know the difference.

Why Temperature is Important When Paving Asphalt

Asphalt is a hot mix when it comes off of the paving machine.

This allows it to be laid down and compacted into the dense material that makes up the driveway, parking lot, or road of your choice.

However, it's also important to note that the material begins to cool down almost immediately after it leaves the paving machine.

That being said, not all temperatures are optimal when it comes to laying asphalt.

Compaction is one of the most important aspects of any paving project.

If the material cannot be properly compacted, it will leave voids in the pavement structure, creating weak points that let water, air, and other materials into the asphalt from above.

In the harsh Midwest winters, that can be an issue in Northwest Indiana.

Why Air Temperature Alone May Not Tell the Full Story

As you might have guessed, air temperature is an important factor when it comes to paving in the colder months.

While it doesn't tell the full story, it can give a general idea of how paving may go on a specific day.

The short answer is that it's not the only factor that matters.

While a 55 degree day may seem nice and warm, if the ground is still holding the deep freeze from the night before, it may be harder to keep the heat in the asphalt to allow for the correct amount of compaction to take place.

The same goes for wind; a colder day with wind will rob the asphalt of its heat faster than a still, cold night.

The thickness of the asphalt being laid can also be a factor in how quickly it can cool.

That's why it's so important to evaluate conditions on a case by case basis rather than looking at a calendar.

What Temperature is Too Cold to Pave Asphalt?

There really isn't a defined answer to this.

It all depends on what kind of asphalt is being laid, what thickness is being used, what conditions are being worked with, and much more.

In general, it's always a good idea to work with warm and dry conditions that allow for enough time to lay and properly compact the asphalt before it has a chance to cool.

The Federal Highway Administration has more information about asphalt pavement construction and preservation in general that may be of interest to anyone looking to get a better idea of exactly what goes into a paving project. The technical details may be a bit dry at times, but it's all there; anyone can find the information they need for their own project.

As for homeowners and business owners alike, we can break this all down into a very simple statement; just because it's cold outside doesn't mean that you can't pave.

It just means that a little extra work may be required.

Why It Can be Tricky in Michigan City

Anyone who has spent any amount of time around Michigan City and the surrounding region knows that the weather can be fickle at times.

One day it may be warm and sunny, the next it can swing to the other direction of the thermometer and make the roads and sidewalks slick with moisture from Lake Michigan.

The National Weather Service is the official source for Northern Indiana's weather, including precipitation, freezes, and much more.

The variables are real, which is why we hate giving a definitive answer about a paving deadline.

It's much more complicated than "we stop paving on this specific day".

There are some years where it can be later than others. There are other years where we have to bite the bullet and move on due to early winter conditions.

It all depends on what's best for the conditions on the ground at the time.

What Happens if You Pave Asphalt When It's Too Cold?

This is where the "it doesn't matter if it's cold outside" attitude can lead to some very expensive problems.

If the asphalt was too cold when it was laid, it likely didn't reach its full compaction potential.

While it may not be immediately obvious, the effects of improperly compacted asphalt can linger long after the installation is complete.

Water can become trapped beneath the surface of the pavement, causing premature deterioration.

Cracks may appear sooner than expected.

Then, if water does manage to make its way beneath the surface, it can cause the ground to freeze beneath the pavement.

This can put additional stress on the asphalt from below.

All of these stresses, some of which may not be obvious at the time, can lead to a much more expensive repair down the line.

We cover the effects of the freeze thaw cycle on asphalt pavement in much greater detail in our How Freeze Thaw Cycles Damage Asphalt in Michigan City guide.

Is Fall a Good Time to Pave Asphalt?

Absolutely, if the conditions are right.

People will often try to time a paving project to take place in the middle of the summer.

There's nothing inherently wrong with this, but it's not always necessary.

There can be ideal paving conditions all the way into early fall in Northwest Indiana.

As a matter of fact, some people like to work with this kind of weather for both comfort and functionality.

However, once air temperatures start to become more fickle, nighttime temperatures start to drop drastically, and the ground really starts to cool down, the clock starts ticking.

That's when asphalt delivery, installation, and compaction have to move faster.

What About Paving Asphalt in the Spring?

The spring season can be a great time to pave in many ways.

It has the advantages of the warm summer air, combined with the benefits of moisture in the ground from the previous winter.

That being said, there is one factor that can make things tricky in the early months of the year.

Moisture.

After a long winter, the ground can be particularly susceptible to holding on to water.

This means that any potential drainage issues that may exist will be much more apparent.

It may sound like a bad thing, but it really isn't.

In some ways, we actually prefer it.

Drainage issues on a driveway, parking lot, or other asphalt pavement are much easier to deal with before paving takes place rather than trying to repair and/or replace a driveway after the fact.

The Ground Matters Just as Much as the Weather

We say this a lot, and it's always going to be an important point in asphalt paving.

Good pavement cannot fix a bad substrate.

If the ground beneath the future pavement is soft, wet, poorly drained, or otherwise unsuitable for installation, laying asphalt over it will not fix those problems.

It may even make them worse.

This is especially true in Northern Indiana, where the ground can be prone to freezing every winter.

Pavement thickness, excavation and preparation, and drainage all play a part in the final cost of a paving project. All of these items should be taken into consideration when budgeting for an asphalt driveway.

What Should You Do if You Want to Pave but It's Getting Cold?

This is always a difficult situation.

It can always come down to the individual case, but there are some general rules of thumb that apply to most situations.

If the driveway is in pretty good shape but just needs some work, it may make sense to hold off on any paving work until the weather warms back up again.

If the ground has cracks that could potentially hold water, it may make sense to address those issues before the winter weather moves in.

On the other hand, if there are large potholes that could potentially damage vehicles, repairs may need to be made immediately.

It's all about identifying the problem and solving it the best way possible under the circumstances.

Sometimes the best option may not be paving at all.

It may instead be stabilizing the problem until more suitable conditions present themselves.

What About Commercial Parking Lots?

When it comes to commercial properties, there is another factor that has to be taken into consideration.

Time.

Whether we're talking about a restaurant, a medical office, a church, or apartments; all of these places have to consider the impact paving can have on their daily operations.

It may be necessary to complete a paving project before the winter weather moves in simply to avoid interrupting the normal flow of business.

Asphalt parking lots also tend to see much higher volumes of traffic than a residential driveway ever would.

This includes large commercial vehicles such as dump trucks, garbage trucks, and more. Add in the turning radius of passenger vehicles and you've got a recipe for stress on the parking lot pavement. This is why commercial lots require such a careful, methodical approach when it comes to paving.

We cover some of these topics in more detail in our Parking Lot Paving Cost in LaPorte County article.

Should You Rush a Paving Project Before Winter Moves In?

If the conditions are right, there's no reason why a paving project can't take place in the later months of the year.

However, simply trying to time the project to beat the winter weather can be a bad idea in many situations.

It's always good to pave the driveway or parking lot while the conditions are the best they can be, regardless of what month it is.

A driveway or parking lot paving project is simply too important to rush just to try and beat the cold weather. If waiting several months means a better paving job overall, it's almost always a better option.

Can You Replace Asphalt in the Winter?

After the ground has frozen solid and the snow has moved in, most paving projects are out of luck.

It's simply too cold to do a full scale paving project in the dead of winter.

However, emergency repairs can be made to potholes or other damages that could potentially cause a safety hazard.

Asphalt contractors will always recommend against winter paving, unless there are exceptional circumstances.

If you own a commercial parking lot, snowfall and ice can greatly impact the amount of traffic the lot can handle.

Potholes and other defects in the pavement can also be a major safety concern.

Emergency repairs can be made to these problems, while larger scale repairs can be saved for better weather.

It all comes down to the situation.

Planning Ahead Pays Off

One way to avoid having to ask "can I pave asphalt in cold weather" in the first place is to schedule a paving project ahead of time.

If the pavement on your driveway or parking lot is starting to crack up, sink down, or develop large potholes, don't wait until the first night of freezing weather to start looking into replacement.

This is especially true for commercial parking lots. It's always a good idea to schedule an inspection well ahead of time to be prepared when the time comes.

It's always a good idea to be prepared, whether you're dealing with a residential driveway or a commercial parking lot.

Frequently Asked Questions About Cold Weather Asphalt Paving

Can asphalt be paved in 50 degree weather?

It can be possible depending on ground temperature, wind, asphalt thickness, mix requirements, and other job conditions. Air temperature alone should not be used to make the decision.

Can you pave asphalt if the ground is frozen?

A frozen or unstable base creates serious concerns for proper pavement installation. The condition of the ground should be evaluated before paving begins.

Is summer the best time to pave?

Warm summer conditions are favorable, but quality paving can also be completed during suitable spring and fall weather.

Can asphalt be paved in the rain?

A wet surface can interfere with paving and proper bonding. Asphalt paving is generally planned around dry conditions.

What if I have a pothole during the winter?

Temporary repair options may be available for safety concerns, with more permanent repairs scheduled when conditions allow.
