Asphalt Crack Repair — Sealing Versus Filling

Excessive use, poor drainage, temperature fluctuations, and subpar installation techniques can result in a series of cracks forming in a commercial asphalt parking lot. There are several common crack formations and varying sealing and filling applications that can prevent cracks from growing and restore the integrity of a paved surface.

Different Crack Formations

During the winter, rainwater will seep into cracks. If the temperature dips down below freezing, the ice will expand and apply pressure to the asphalt surrounding the cracks. This often results in a crack widening and lengthening. There are many common crack formations, including square-shaped cracks, horizontal and vertical lines, and webbed cracks.

Paving contractors classify cracks as either working or non-working based upon the size of a crack and the direction in which it is located on a paved surface. The severity of a crack and the likelihood that increased damage will affect the pavement's sublayer will have a bearing on whether a paving contractor will recommend a sealing or filling repair process.

Sealing And Filling Procedures

A sealant is rubberized and will form a bond that is impenetrable. The sealant will remain flexible with the pavement that surrounds it, ensuring that motorists experience smooth movement as they pass over sealed surfaces. A sealant is considered a long term repair.

Sealant procedures may be much more expensive than patching ones, but you won't need to deal with any more issues associated with your commercial lot. Filling procedures involve adding a liquid emulsion to the damaged portion of a lot. Each crack is measured and filled separately. The emulsion consists of an aggregate blend, which contains liquid ingredients and small particles that are necessary for binding purposes.

Some paving contractors recycle pavement, which can also be used to fill cracks and holes. A recycling method involves using an electric machine. The recycling machine will break down old asphalt and soften it, allowing the product to be used as a filling agent. Consult with your paving contractor and let them know what your goals are.

If you are going to be operating your business from the same premises for many years and the appearance of the lot is important to you, sealing the pavement will provide a flawless finish. If you are not able to spend a lot of money and are only concerned about preventing the cracks from growing larger, a filling process will be ideal.
