7 Signs You Need a Mill and Overlay

When it comes to private road construction, something like an asphalt driveway is an investment – and it’s one that should always be protected. That includes paying attention to certain warning signs that indicate a mill and overlay would be highly recommended for not only your driveway, but for also sidewalks and other private roads you may be dealing with. 

Asphalt Chipping

One of the most immediate signs that you need a mill and overlay comes by way of any asphalt chipping that you may be experiencing. This is most commonly caused by structural stress and a mill and overlay can help cut down on this a great deal.

Large and Deep Cracks

Large and deep cracks are similar warning sign in that they are caused by overloading thin driveways, sidewalks, or private roads. Note that these cracks will need to be properly repaired prior to the mill and the overlay being added.

Numerous Small Cracks

Numerous small cracks are usually caused by weaker base materials. However, excessive stress and even poor drainage can also exacerbate the issue significantly.

Large Potholes

If water is allowed to seep into any of those aforementioned cracks that you’re seeing with your driveway, sidewalk, or private road, it is highly likely that you’ll be looking at potholes in your future. That water then freezes and expands and when it thaws, it causes those cracks to turn into potholes. Luckily, a mill and overlay can help with all of this.

Numerous Pockmarks

One clear warning sign that you need a mill and overlay has to do with numerous pockmarks forming over a (relatively) short period of time. This, too, is usually caused by one of a few unfortunately common reasons – like a lack of repairs, maintenance and general upkeep over the years, weak materials used in the subgrade, and poor construction overall. These pockmarks will likely continue to worsen and form full-fledged potholes if they aren’t addressed as soon as possible.

Faded Color

Obviously, an asphalt road, pathway, or driveway is going to be exposed to the elements constantly. As time marches on, and it sees a constant exposure to not only the sun and heat but also rain, wind, and even snow in some parts of the country, the asphalt coating will slowly begin to degrade. That will not only leave your asphalt more susceptible to normal wear and tear like cracking, but it will also cause it to fade in color far easier, too.

Widespread Oil Staining

Let’s face facts – sometimes, your car leaks oil or other types of chemicals. But if you don’t clean up those spills right away, a number of bad things can happen. For starters, that stain will become harder and harder to clean – creating an unsightly appearance. But also, that oil can seep further into the asphalt and cause additional damage like cracking. A mill and overlay can help take care of all this and more.

If you’d like to find out more information about the signs to watch out for to let you know that you might need a mill and overlay, or if you just have any additional questions about things like private road construction that you’d like to go over in more detail, please don’t delay – contact us today.

Highways Designed with Snow and Cold in Mind

One of the more critical things to consider when it comes to asphalt construction is also one of those things that most people just don’t spend too much time thinking about: the climate.

An asphalt highway in an area that is traditionally hot all year round like Texas may look the same as one that exists in Maine – at least on the surface. But the latter is located in a place that gets particularly cold winters and that is something that absolutely has to be taken into account. In fact, there are a number of important components to highways that are designed with snow and cold in mind that you should absolutely be aware of moving forward.

Temperature Extremes

One of the major ways that highways are designed with snow and cold in mind has to do with what happens to materials like asphalt during extreme changes in temperature.

Keep in mind that materials expand and contract as the weather changes around them and unless this is accounted for, it could result in significant cracking at best and a serious compromise to the integrity of the highway at worst. In Bangor, Maine, for example, the leverage low in January is just 7 degrees Fahrenheit. By April, the average high is 53 degrees Fahrenheit. That’s a significant difference and over time that could cause premature and long-term damage to the highway itself if it were not a factor in the design.

Drainage

Because asphalt is porous, it actually performs better than other types of materials in colder weather. However, this comes with a cost. Because the ice and snow melts faster, drainage has to be a top priority.

Thankfully, PVC drain piping (and a layer of gravel under the surface) go a long way towards accomplishing these goals. Not only does it help keep the highway safe, but it also reduces the overall amount of salt that needs to be used to treat the roads during the winter as well.

Fencing Around Asphalt

Snow fencing is another technique that is commonly used to preserve safety and performance for highways that are located in areas that get a lot of snow. Snow fencing can actually be put up as the colder weather approaches, and it’s a great way to prevent drifts from appearing on the road, thus putting drivers in a significant amount of harm during extreme storms.

Road Slope and Bridge Design

Finally, a lot of people don’t realize that even the pitch of the road is taken into consideration in areas that see a lot of ice and snow during the cold winter months. Highways in rural areas, for example, have a banked curve of no more than 5% to help prevent issues like sliding. Bridges on these highways are also constructed with a protective coating to help prevent premature corrosion due to the massive volumes of road salt that get used every year as the temperatures start to drop and ice builds up.
