Why Asphalt Driveways Crack and What Smart Homeowners Can Do to Prevent Damage

Asphalt drives are tough and appealing, but they are prone to damage. The cracks will occur over time even in the best-installed driveway unless it is maintained. The good news? A majority of the damage can be avoided with some simple practice. The North Georgia homeowners can increase the life of their asphalt by several years.

What Makes Asphalt Crack?

Asphalt is flexible; it is meant to resist changes of temperature and vehicle pressure. However, under the influence of constant loading, pressure, or weight, the substance that helps the material to stick together starts to damage. When the surface becomes weak, cracks start showing, and they gradually widen when not treated.

Top reasons for driveway cracks.

1. Excessive Load and Heavy Vehicles

Asphalt will be able to accommodate ordinary cars and SUVs, but on a regular basis, it is the heavy trucks, RVs, trailers, or construction machines that will constantly put a strain on the pavement. After some years, the load will make the asphalt bend way out of proportion, leading to surface cracks, depressions, and structural vulnerability.

Prevention Tips:

When parking heavy cars on the driveway, do not spend too much time.

Parking spaces should be rotated rather than lying in the same area.

Install paving reinforcement in case your house is frequented by heavy vehicles.

2. Freeze-Thaw Cycles.

Weather is the main destroyer of driveways in cold areas. Here’s what happens:

• Water seeps into tiny cracks.

• Cold water solidifies and extends the crack.

• When the ice water melts, it settles deeper.

The process repeats itself, and cracks are getting bigger by each season.

During hot summers, asphalt becomes soft and more flexible and cracks appear on the surface.

How to Spot It:

• Spiderweb cracks

• Pothole formation

• Cracks that enlarge following winter.

3. Natural Aging:

Any asphalt surface will damage with time even with flawless maintenance. The binder is dried gradually by the UV rays and oxygen, and the surface becomes brittle. Old asphalt can no longer bend under pressure, then the cracks begin to appear, and there is no particular reason.

Signs of Aging Asphalt:

• Faded gray color

• Rough, brittle texture

• Several surface cracks on the surface.

4. Poor Preparation of Base and Lack of Good Installation

Poor installation is one of the most widespread and costly reasons for cracking. A driveway is as solid as the surface on which it is built. Failure by the contractor to properly compact the soil, apply the wrong asphalt mix, or apply the same on wet ground will cause the surface to crack long before the time it should.

Red Flags of Bad Installation:

• Uneven or wavy surface

• Premature cracks in 1-2 years.

• Ponding of water at some points.

5. Water Damage and Drainage Problems.

Water causes asphalt driveway failure. When there are puddles in your driveway, an inappropriate slope, or water in the cracks, the layer that underlies them becomes fragile.

When the foundation is weak, the pavement over it becomes unsupported, and cracks begin to appear.

Warning Signs:

• Standing water after rain

• Soft or spongy spots

• Fissures developed in a straight way (generally along drainage lines).

6. Tree Roots and Soil Movement

The roots of trees do not have to be very large in order to do harm. They swell and press under the asphalt, which leads to cracks, raised parts, or buckling.

The soil can also be unstable or compacted poorly, which causes the soil to move with time, resulting in uneven settling and cracks on the surface.

Prevention Tips:

• Plant trees at a distance of 10-15 ft away from driveways.

• Install root barriers.

• Before installation, have soil correctly compacted.

How to Avoid the Damage of Driveways?

1. Sealcoat Every 2–3 Years

One of the most inexpensive and also simplest methods of providing protection to asphalt is sealcoating. It protects the surface against UV rays, water, oil, and other chemicals. It makes the asphalt flexible and strong.

Benefits of Sealcoating:

• Extends lifespan by 5–10 years

• Prevents oxidation

• Helps resist cracking

2. Fix minor cracks before it is too late.

A little crack today would be a pothole tomorrow. Sealing the cracks does not allow water to penetrate the base to continue the damage.

Fix cracks when they are:

• 1/8” to 1/2" wide

• Straight or hairline cracks

• Newly organized and not transmitted.

3. Enhance the Drainage System of the Driveway

Due grading will make sure that water does not move towards asphalt, but it moves off. Enhancing drainage will minimize any possibility of water intrusion and base erosion.

Simple fixes include:

• Adding a French drain

• Resloping the edges

• Unblocking blocked gutters that pour down the driveway.
  
  

4. Sharp turning or parking on hot asphalt is to be avoided.

During hot summers, the asphalt becomes soft. The sharp turns of the steering wheel or intensive parking may scratch the surface and make premature cracks.

5. Keep the Driveway Clean

Asphalt gets weakened by oil, chemicals, and debris. To sustain its strength and its appearance, cleaning is performed.

Do this monthly:

• Sweep debris.

• Wash off oil stains.

• Get weeds growing between cracks out.

 

Best Method of Repairing Cracks?

The cost, condition, age, and long-term reliability of your pavement are factors that should be considered before deciding whether to repair or have a complete replacement. The following table will further subdivide the key factors in order to enable the property owners to make an informed, low-budget decision.
