How Heat Affects Your Asphalt Parking Lot


How Heat Affects Your Asphalt Parking Lot

Asphalt is designed to be a long-lasting and low-cost pavement material for parking lots. But just like any other construction material, asphalt goes through stages of wear and tear when confronted with the rigors of weather, particularly here in the southeastern United States.


In this post, we'll dive into the impact of heat on your asphalt parking lot and unveil strategies to safeguard its longevity and integrity.


Faded Line Striping

Your parking lot's striping is a visual guide and a safety marker for drivers and pedestrians alike. However, the unrelenting sun can play havoc with these essential markings. Prolonged exposure to high temperatures can lead to the fading of parking stripes and directional indicators, potentially creating a hazardous environment.


To counter this, it's advisable to refresh the striping after a routine maintenance or repair work is done on your asphalt lots.


Weaker Pavement Structure

An asphalt pavement is made up of aggregates like crushed stones, gravel, and sand, and then a binding agent is also added to make the aggregates stick together. Unfortunately, this high heat will also break down this binding agent called bitumen, which makes the remaining surface prone to cracks and water infiltration, which leads to the further deterioration of the asphalt.


Protect your asphalt parking lot during the extreme heat conditions by investing in asphalt sealcoating. This protective layer will keep the binder and the asphalt surface strong and durable during the summer.


Weakened Pavement Integrity

Asphalt pavement is made up of aggregates such as crushed stones, gravel, and sand, bound together by a binding agent known as bitumen. However, the intense heat can accelerate the breakdown of this binding substance, leaving the asphalt cement susceptible to cracks and water infiltration. These cracks, if left unchecked, can lead to further deterioration of the asphalt, impacting both its structural integrity and visual appeal.


To fortify your asphalt parking lot against the effects of extreme heat, consider investing in sealcoating. This protective layer acts as a shield, reinforcing the binder and the asphalt surface, ensuring resilience during the scorching summer months.


Pavement Expansion

Similar to other construction materials, asphalt contracts in colder conditions and expands under the sun's warmth. However, when temperatures soar to unprecedented heights, this expansion can trigger a range of issues. Pavement edges may curl, pre-existing cracks may widen, or entirely new cracks may emerge due to the pavement's movements caused by the heat.


Any visible cracks, potholes, or signs of summer heat damage should be addressed before the arrival of snow and freezing temperatures. Timely repairs in the transitional phase between summer and autumn can prevent these issues from exacerbating.


Ready to Defend Your Asphalt Parking Lot from the Heat?

Asphalt, although resilient, is not immune to the potent effects of heat, especially in the southeastern United States. Regular maintenance, timely striping refreshes, asphalt sealcoating, and strategic repairs all play integral roles in preserving your parking lot's functionality, safety, and aesthetic appeal.
