What Happens When It Rains? The Effects Of Rainfall On Asphalt Pavement

Residents of New Jersey are no stranger to high-intensity, excessive rainfall. Whether it is Hurricane Irene (Aug 2011) or Superstorm Sandy (Oct 2012), we’ve seen a fair share of inclement weather in the past few years. The intense weather poses health and safety hazards for the residents, so you should take proactive measures to protect yourself and your family.

Thunderstorms and severe rain can also damage your property, including your asphalt pavement. An inadequately maintained pavement is especially vulnerable as the rain can damage the surface beyond repair. An asphalt surface’s naturally porous nature makes it susceptible to rain damage. If you want to keep your pavement safe from rain damage, have regular maintenance performed by an experienced contractor like C.H. Paving and Sealcoating in Bridgewater, NJ.

This blog post lists some ways in which extreme weather can damage your asphalt pavement and the steps you can take to limit the damage.

How Rain Damages an Asphalt Pavement

Rain is a big problem for asphalt pavement because it weakens the sealant that binds aggregate particles together. The rain seeps into the cracks and damages the surface, leading to potholes down the line. When water leaks deep enough through your asphalt driveway or parking lot’s surface, it can weaken its structural integrity in just minutes!

You can prevent this damage before it happens with regular maintenance like washing off any dirt on top of your asphalt and repairing any small cracks you see from time to time. If you have an issue with standing water appearing after heavy rainfall (which will lead to further problems!), checking the drainage may also be necessary.

Asphalt Shrinkage

Rainfall can cause asphalt surfaces to shrink. This is because as the water seeps into the ground, it causes the material under an asphalt surface to expand and swell; this can lead to cracking or buckling of a pavement’s surface.

This process can be partially remedied by maintaining proper drainage systems so that rainwater doesn’t accumulate at one location on your property (which will also help you avoid mud puddles). If you see cracks forming in your sidewalk or driveway after heavy downpours, then seal them with caulking before they get bigger!

Oil Separation

It is essential to understand that the whole deterioration process begins when the oil and bitumen in asphalt seep out of the material. The rainwater separates oil from asphalt to repel water.

Preventing Asphalt Damage

Correct installation and regular maintenance are crucial for preventing asphalt damage. If you have a water-sealed drainage system, it will stand up to heavy rainfall without much additional care.
