There is no doubt that the asphalt takes a beating every day. Every season comes with temperature changes and this alone is enough to accelerate the deterioration. Freeze and thaw cycles cause expansion and contraction leading to cracks. The cracks allow water to seep into the asphalt and as the water freezes, it expands and makes the cracks bigger. In the case of parking lots, the constant traffic wears out the Sealcoating, and the fuels and chemicals from the vehicles cause the asphalt to dissolve.
To extend the lifespan of your asphalt, you need to ensure that the asphalt is properly protected by the sealcoat. The sealcoat acts as a skin for the asphalt. It shields the lower layers of asphalt from the daily impact of weather, chemicals and traffic. It is a key component in any asphalt maintenance program and more so in parking lots.
What to look for
When installing asphalt, you should know what to look for. There are three things you should look for:
1. The drainage and stability
2. Frequency and size of cracks
3. Amount of oil on the surface
Those three factors will dramatically impact the quality and lifespan of the asphalt. It will also determine the application and performance of the sealcoat.
Applying a sealcoat is simple as it is a matter of waiting for the newly laid asphalt to cure and for the oils to dissolve. It is recommended that 6 to 12 months of cure time be allowed. Water flowing smoothly down the asphalt is a good sign that the oil has dissolved. You can run a test by simply pouring water on the asphalt and watching for rings or breaks in the flow.
For old asphalt, the process is harder. When inspecting it, look for cracks or patches that may need sealing or replacing. Depending on the age of the asphalt, it may require to be prepared before the sealcoat is applied.
