There are many contributing factors that make asphalt a great material to use when paving a parking lot or an asphalt driveway. It is a relatively inexpensive material when compared to other material such as concrete or concrete paving blocks. Asphalt is a very durable product that stands up well to basic wear and tear of vehicle and foot traffic. Another great reason to use asphalt for your paving needs is that asphalt is a green product that is recycled more often than any other paving product.
Here are a few tips that will help you if you already have an asphalt driveway or parking lot surface that is in need of repairs. Although asphalt will need maintenance from time to time, it will only help in keeping future repair cost down to a minimum. If you are trying to do your own maintenance repairs, you will want to complete the repairs properly in order to get the maximum life out of your pavement. If you are hiring a contractor to handle the repairs for you, a little education on what to look for will help you choose the right contractor and also help you know what to look for once their on the job.
Asphalt maintenance should be done periodically as needed. Sealcoating is one way to protect against water undermining the asphalt and reaching the base material beneath the asphalt. Ultraviolet rays can break down the binder material in asphalt allowing it to become brittle and fall apart. Sealcoating will give your asphalt surface protection against the ultraviolet rays. Sealcoating should be mixed to the proper specifications and should not be diluted to in order to stretch out the product. This will not give the asphalt the same protection. The first coat can be sprayed on to ensure the material gets into the smaller cracks to seal off and stop any future water penetration.
If you have areas in your asphalt pavement that have potholes or noticeably large alligator cracks you may need to remove these areas in order to repair them correctly. The first step in this process is to cut out the affected area with a saw. Next, you will need to remove any excess materials from the affected area. Once the area is cleaned of any debris, apply a tach coat to make the new hot asphalt adhere to the cut out area. Then apply the new asphalt, and always make sure to compact the newly installed asphalt.
