A shiny new asphalt road can be tempting to drive on, particularly when the newly paved surface is smooth and welcoming. Nevertheless, it is important to know what one gets into by driving on fresh asphalt before venturing out on it. This article will discuss why it is usually not recommended to drive on new asphalt and what to take into account if you want to drive on a newly paved road.
Understanding Fresh Asphalt
What is Fresh Asphalt?
Fresh asphalt is a combination of aggregates and bitumen which has been spread and compacted to form a smooth, durable road surface. The process entails various stages such as preparation of the old surface, installation of the new asphalt, and curing. New asphalt is usually hot and soft right after its application, this is why it needs time to cool and harden.
The Importance of Curing
Curing is an important stage of the asphalt paving process. During this period the asphalt changes from a soft pliable state to a hard durable surface. The curing process may last from a few hours to several days, depending on temperature, humidity, and thickness of the asphalt layer. Driving on newly laid asphalt before it has cured will do a lot of damage to the road and the vehicle.
Why Driving on Fresh Asphalt Is a Bad Idea
Damage to the Asphalt
Distortion of the Surface
When new asphalt is put under the weight and pressure of vehicles, it can distort. This can result in ruts, ripples, and other imperfections in the surface of the road compromising the integrity of the road. Such imperfections do not only spoil the visual appeal of the road but can also pose a danger to the drivers.
Reduced Longevity
Driving on new asphalt can considerably decrease the life of the road. The premature wear and tear resulting from vehicles can cause the need for repairs and repaving much earlier than one would expect. Not only does this incur extra cost, but it also complicates traffic and inconveniences the community.
Damage to Your Vehicle
Tire Damage
New asphalt is very hot, sometimes exceeding 300°F (150°C). Driving on such surface can result in serious wear and tear of your tires. The heat may melt the rubber causing flat spots, blowouts, or complete failure of the tire. Not only is this a safety hazard but also a costly repair or replacement.
Undercarriage Damage
Apart from damage to tires, the undercarriage of your vehicle can also be damaged. The extreme heat from the new asphalt can distort or melt parts like exhaust systems, brake lines and other metallic parts. This can cause costly repairs and even safety risks.
Indicators That Asphalt is Suitable for Traffic
Temperature Checks
The temperature is one of the most dependable indicators of whether asphalt is ready for traffic. As asphalt cools it hardens and becomes more resilient. Contractors tend to use infrared thermometers to determine the surface temperature of the asphalt. As a rule, asphalt is considered safe for traffic when cooled down to 90-100°F (32-38°C).
Curing Time
The time for curing asphalt can depend on the environmental conditions. In warmer climates, asphalt may cure faster, but, in cooler climates, the curing process may take longer. On average, it takes about 24-48 hours for the asphalt to cure sufficiently to tolerate light traffic, like emergency vehicles and construction equipment.
Visual Inspection
An inspection by sight can also be used to establish whether asphalt is ready for traffic. Newly laid asphalt will have a shiny reflective surface. As it heals, this shine fades and the surface start to look more matte. Also, lack of tire tracks or ruts is a good indication that the asphalt has hardened to a point where it can support traffic from vehicles.
What to do When You See Fresh Asphalt
Follow Road Signs and Barriers
If you come across a newly paved road, then you should pay attention to road signs and barriers. Construction crews usually use “Do Not Drive on Fresh Asphalt” signs and barriers to keep vehicles out of the area. Disregarding these warnings can lead to your vehicle and the road being damaged and face legal consequences.
Detours and Alternate Routes to Follow
Detour signs are usually part of construction projects to help drivers navigate the work zone. It is necessary to take these detours and make use of alternate routes to avoid driving on fresh asphalt. Though inconvenient, detouring helps to ensure your vehicle’s safety and the longevity of the road.
Report Concerns to Authorities
If you observe that vehicles are using fresh asphalt despite warning signs, it’s important to report this to relevant authorities. Contact the local department of transportation or the construction company in order to solve the problem and avoid further damage.
Driving on new asphalt is a risk not worth taking. The damage to the road and your car will be much more than the convenience of taking a shortcut. By knowing the importance of the curing process and observing road signs and detours, you can help make newly paved roads safer and longer lasting. Never rush when dealing with new asphalt, and keep in mind that a few extra minutes on an alternative route will prevent you from having to pay for costly repairs and provide a more comfortable ride in the long term.
