Is Asphalt Crack Sealing Effective?
If an asphalt pavement is to achieve its projected life expectancy, it will need to be properly maintained. Cracks can lead to the premature failure of the pavement, so it is essential to have asphalt crack sealing performed as soon as you notice that your pavement is damaged. Asphalt crack sealing is an economical and effective way to add years to your pavement’s useful life.
Is Asphalt Crack Sealing Effective? How Can Crack Sealing Extend the Life of Asphalt Pavement?
When it comes to asphalt pavement, water is a formidable enemy. The pavement is supported by a compacted foundation. If this foundation becomes unstable, potholes, low spots and large cracks can develop. Water penetration is the leading cause of foundation instability. The water flows through the cracks and erodes the foundation. When the trapped water freezes, it will expand, causing additional damage to the foundation as well as the pavement.
Automotive fluids can also contribute to the deterioration of asphalt pavement. Oil, gas, brake fluid and other automotive liquids will break down the binder that holds the pavement together. The pavement will become soft, crumbly and easily dislodged. Cracks can allow automotive fluids to penetrate beyond the surface of the pavement and the sealcoating that helps slow their penetration.
Having a professional apply a crack sealer is the best way to protect against the penetration of water and automotive fluids. Crack sealing is a durable repair method that can be used on most cracks in asphalt pavement. However, it should be noted that crack sealing cannot save pavement that has developed alligator cracking. Alligator cracking usually indicates a damaged foundation, so removing and replacing the affected area is normally the only way to repair the damage.
Is Crack Filling the Same as Crack Sealing?
Many people use the two terms interchangeably, but they are not the same. A crack sealer is a flexible, rubberized material that will expand and contract with the pavement. An asphalt crack filler is a non-rubberized material that lacks the flexibility of a crack sealer. When the pavement expands or contracts, the crack filler may separate from the walls of the crack, leaving an opening that is exposed to the elements.
Another crucial difference between filling and sealing is the application method. Filling typically involves introducing the asphalt crack filler into the crack only. Sealing usually involves filling the crack as well as capping at the surface level.
Crack filling is unsuitable for cracks that are expanding or widening. Asphalt professionals refer to these as working or active cracks. Crack filler is usually reserved for edge, block or joint cracks. For most horizontal and longitudinal cracks, crack sealers normally deliver better results. However, only an experienced asphalt contractor can make a proper assessment to determine which method should be used on a specific pavement.
