Asphalt, the backbone of modern driveways and parking lots, offers durability and longevity. Yet, over time, even this robust material can succumb to block cracking. Recognizing the causes of these unsightly and potentially damaging fissures is crucial for any property or company owner. Let’s examine the main causes of block cracking in asphalt and how sealing solutions from NAC Supply can extend the life of your pavement.
Block cracking in asphalt manifests as roughly square or rectangular cracks that carve up your pavement. They may start small and relatively harmless. However, over time, they can transform into larger issues, leading to a decrease in pavement integrity and a rise in repair costs. Keep reading to discover the primary causes of this phenomenon.
One major offender in block cracking is subpar construction. If the crew who did the initial paving job poorly executed, perhaps due to low-quality materials, inadequate compaction, or improper temperature during installation, this can lead to block cracking. This is why you must use the proper materials and procedures when using asphalt.
The passage of time inevitably brings about wear and tear in the form of oxidation and weather damage. Asphalt bitumen loses its elasticity and becomes brittle as it ages, leading to cracking under the stress of recurring traffic loads. Additionally, oxidation from exposure to the elements can weaken the asphalt and make it more susceptible to block cracking.
Asphalt pavement can withstand the weight of vehicles, but there’s a limit to its bearing capacity. When overloaded with heavy trucks or numerous vehicles, asphalt may start to crack and eventually give in to block cracking.
Thermal expansion and contraction are natural responses to the changing climate, but these can wreak havoc on unprepared asphalt surfaces. In regions where temperatures swing dramatically, asphalt expanses will crack as they repeatedly swell in the heat and contract in the cold.
It's not all doom and gloom. Understanding the main causes of block cracking in asphalt gives us a fighting chance to prevent or mitigate the damage. Employing quality asphalt crack sealing products is the next logical step to protecting your investment.
Whether age or substandard materials have led to block cracking in your asphalt, the solution lies in timely and effective treatment. Acknowledging the primary causes of block cracking in asphalt is just the first step. The crucial act that follows is choosing a reliable path for repairs.
