Though you may not notice initially, over time cold and snowy weather will affect the structural integrity of asphalt pavement. If the damage is not addressed accordingly, it can lead to expensive and time-consuming repairs. Below we’ll describe some of the different factors of cold weather conditions which can cause damage to asphalt. With this knowledge, you can be proactive in protecting your investment.
Understanding temperature fluctuations
When water freezes it expands and can enlarge existing cracks in paved areas. Additionally, compromised asphalt material can create potholes. As surrounding ice melts, it can seep into the sub-base layer which weakens its structural integrity. In Murfreesboro, sealcoating professionals apply a layer of protective coating on the pavement to make it resistant to water, oil, and other substances.
To salt or not to salt, that is the question
Salt can be used to de-ice asphalt pavements which creates a more stable surface for tires. While salt does not necessarily cause asphalt to deteriorate, it can aggravate any underlying issues. Salt lowers the freezing temperature of water, which can cause water to seep into existing cracks and expand when freezing, which can cause bigger cracks to form. Before the onset of the snow season, get in touch with an experienced asphalt patching provider in Murfreesboro to repair existing potholes and prevent future damages. Finally, melted salt can have a negative effect on plants and wildlife when it mixes with local bodies of water.
Snowplows can unknowingly cause damage
Snowplows are mounted on vehicles and can quickly and efficiently remove snow and ice. They are also an essential tool in locations that experience heavy snowfall. However, they often scrape the surface of asphalt pavements repeatedly, which can remove protective layers and coatings and expose asphalt to the elements.
Although using a snowblower may be a slow and tedious process, it can minimize the risk of damage to protective coverings on the asphalt. Weigh the pros and cons of each alternative before you proceed.
The quality of the sub-base is important
The ability of asphalt pavement to withstand extreme weather conditions mainly depends on the type of sub-base used and how it was installed. Many contractors believe using 5 to 6 inches of full-depth asphalt is a strong sub-base and durable enough for different climates and loads. Some opt for crushed gravel as a sub-base. It pays to invest in a high-quality sub-base. consult with a reputable asphalt paving contractor to determine what meets your requirements and to ensure a professional installation.
Consider porous asphalt
Asphalt has a dark color, which means it can absorb more heat in sunlight. Subsequently, snow and ice melt faster on asphalt than on other surfaces. However, if asphalt is not properly installed and can not manage water runoff, it can lead to the pooling of water. As an alternative, porous asphalt is an eco-friendly material that allows water to drain through and return to the soil and water table.
The key to long-lasting pavements is to work with asphalt repair experts who can help you make qualified and informed decisions on your project.
