The Silent Guardians: How Asphalt Companies Enhance Road Safety

The Critical Role of Pavement Markings

Pavement markings on commercial asphalt serve as a fundamental element in road safety, guiding millions of drivers every day. Asphalt companies, the unsung heroes in this narrative, ensure that these surfaces are not only smooth and durable but also effectively communicate vital information to all road users. The lines, symbols, and signs painted on the road form a universal language of safety, meticulously applied by these companies to direct traffic, prevent accidents, and save lives.

The Quality of Asphalt and Markings

The interplay between the quality of asphalt and the effectiveness of pavement markings is a critical focus for asphalt companies. High-quality asphalt provides a conducive canvas for durable and visible markings. These companies use advanced materials like thermoplastic and reflective paint to ensure that markings remain visible under various conditions, such as at night or during inclement weather. The expertise of these companies in selecting and applying the right materials is essential for the longevity and effectiveness of road markings.

Strategic Importance of Markings

Pavement markings do more than manage traffic flow; they structure the complex interactions between different types of road users. The precision in the application of these markings is crucial, as inaccuracies can lead to confusion and accidents. Asphalt companies leverage their expertise to ensure that each line, symbol, and sign is perfectly placed, providing clear and unambiguous guidance to drivers, cyclists, and pedestrians.

Innovations in Road Safety

Asphalt companies are at the forefront of innovation in road safety. They continuously explore new materials and technologies to enhance the visibility and durability of pavement markings. Innovations like color-coded pavements for specific lanes and reflective beads in markings significantly improve safety for all road users, particularly in low-light conditions.

Maintenance: Keeping Roads Safe

Maintenance of pavement markings is a continuous task undertaken by asphalt companies. Regular inspections and prompt repairs ensure that markings remain visible and effective, maintaining the safety features of the road. This ongoing maintenance is crucial for the longevity of both the asphalt surface and the markings, ensuring that they continue to guide and protect road users.

Collaboration for Urban Safety

In urban settings, where the density of traffic and the diversity of road users are highest, the role of pavement markings is especially critical. Asphalt companies work closely with city planners and traffic engineers to design road systems that accommodate various modes of transport. Through strategic markings, they manage the complex interactions in urban traffic, enhancing safety for everyone on the road.

3 Ways Asphalt and Concrete Surfaces Positively Impact Communities

Asphalt companies have made a significant contribution to our nation’s transportation system by paving roads that are cost-effective, safe, and can withstand the harsh cycles of freezing temperatures. Without asphalt roads that feature a dark surface which significantly reduces glare and is skid-resistant to reduce accidents on wet roads, the number of highway and road accidents would be higher.

There are other advantages of asphalt surfaces that positively impact our communities, making them safer and quieter while adding fuel efficiency.

3 Reasons to Support Asphalt Roads

1. Asphalt is sustainable and recyclable

Asphalt roads have a thick base course along with an intermediate and top wear course which is about 3 inches. When the time comes for resurfacing, it is only the top wear layer that is milled off, then reused to make a fresh new top layer about every 20 years. The underlying courses typically never need replacement and can remain very strong indefinitely.

Because asphalt is 100% recyclable, American taxpayers save billions of dollars each year when municipalities complete roadwork using sustainable asphalt surfaces.

2. Less noise means better communities

The smooth nature of asphalt roadways and the properties of asphalt itself make for a driving surface that is much quieter than other roadway materials. Notice that there are no construction joints on asphalt-paved surfaces. It is these joints that often lift up or buckle, causing noise as trucks and cars drive.

Many states have roadway smoothness requirements that must be met, and asphalt is the easiest way to create roads that are built smoothly and provide an extremely quiet driving surface. And, when the time does come to repair or replace asphalt, it is the quickest road to repair, which eliminates long hours of road construction.

3. Asphalt roads offer better fuel efficiency

The ultra-smooth surface of asphalt means there is less friction between car tires and the road. This adds to driving that is more controllable, more comfortable, and saves on gasoline. Even the construction of asphalt roads is efficient, because it is completed in just a few easy stages, which eliminates rerouting of traffic that can add to a driver’s commute time.

Fuel efficiency trickles down to greater benefits to the community, like better air quality and a smaller carbon footprint. When automobiles have better fuel efficiency, they cost less to operate and maintain. It is estimated that thousands of dollars can be saved by driving on asphalt roads.

Finally, asphalt can be formulated with a number of different additives to fit the different weather and road conditions that exist all over the country. There are some asphalt mixtures that contribute to a smoother surface and some that promote better rainwater drainage.

With the ability to engineer an asphalt roadway solution to fit the unique needs of each community, every one wins with a product that is recyclable, provides a smooth and quiet ride, and contributes to the fuel efficiency of cars and trucks.

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.

What’s the Difference Between Summer Asphalt and Winter Asphalt?

There are many reasons why so many homeowners choose asphalt to pave their driveways, patios, and other outdoor hard surfaces. Not only is it cost-effective, but asphalt is durable, flexible, easy to repair, and is low maintenance. An asphalt driveway can easily last 30 years before needing replacement.

But, how long an asphalt surface lasts depends on the asphalt company you choose and the asphalt mix (or aggregate) the contractor uses – summer asphalt or winter asphalt.

When is the best time to install asphalt?

The optimum temperature for an asphalt installation is when the temperature is between 60 and 70 degrees Fahrenheit. This is the temperature at which asphalt cures the fastest.  But, a good asphalt company can install an asphalt driveway at any time of the year, if they use the right asphalt mix.

Still, timing is important. During the winter, the asphalt company will want to avoid freeze/thaw cycles (for obvious reasons). And, during the summer, asphalt is rarely laid fresh during the portion of the day when the sun’s UV rays are the strongest.

But when it comes to temperature, asphalt manufacturers have developed different formulations to suit each season. There is a summer asphalt (hot mix aggregate) that works better during the higher temperatures of this season. And, winter asphalt (or cold mix aggregate), is designed to be installed during the low temperature months of December through March.

Best Uses for summer asphalt

From spring to the end of fall, summer asphalt is heated to temperatures between 275-325 degrees Fahrenheit, and it is important that the hot asphalt stays within that temperature range as it is being quickly applied. If it cools too much, it should be reheated. Also, the ground surface needs to be warm and dry for an ideal summer asphalt application.

This aggregate is not only best to be applied during warm months, summer asphalt is also better suited for long driveways, commercial parking lots, and public roads.

Winter asphalt applications

Winter asphalt is best for wet and/or cold weather applications. This formulation does not need to be heated constantly in order for the asphalt to adhere well to the subsurface. But, because winter asphalt is poured when the surface is cold, it will take longer to cure.

Still, you can mix and use a batch of winter asphalt and save the remainder for driveway or repairing cracks in your driveway or street patch jobs at any time. While winter asphalt is not ideal for large asphalt installations, it is an easy and economical way to keep your driveway looking pristine when repairs are needed.

For smaller jobs and when you simply want to even out your existing driveway surface for a safer, smoother driveway, then winter asphalt is the go-to choice.

When you partner with a professional asphalt company, they will know exactly the right type of aggregate mix to use, what time of day is best, and in what weather conditions will provide for the best driveway installation. Most driveways in America are paved with asphalt because it creates a skid-resistant surface, which makes your driveway safer to walk and run on. Also, an asphalt surface is smoother and more uniform than other materials.
