Asphalt pavement does not age well. The UV rays of the sun will bake out any residual moisture left in the tar that holds the pavement together. Once this moisture is gone, your pavement will be brittle and prone to cracking. In fact, nothing more than a constant cycle of heating and cooling can cause cracking due to constant expansion and contraction. In order to keep your parking lot in good condition, you need to know the signs of asphalt fatigue so that you can then take the appropriate steps to deal with it.
When the color of your parking lot starts to fade and cracks start to appear, you have your first indication that your parking lot is starting to lose its fight with mother nature. To stave of future degradation, you need to take steps as soon as possible to protect your asphalt. Your first step should be to fix whatever cracks there are. A rubberized joint compound should do the trick. Then cover your pavement with a sealcoat. A good sealcoat will help to seal moisture into your asphalt, seal out petroleum products that could otherwise eat away at asphalt tar, and prevent frost wedging. In other words, a sealcoat will extend the life of your driveway so that you can put off the day when you have to repave the entire parking lot.
If left to its own devices, asphalt will slowly degrade into a web of cracks known as crocodile cracking because of the similarity between the appearance of the asphalt and the scales on a crocodile's back. While it is unlikely that your entire parking lot has succumbed to this level of cracking unless it has been severely neglected for several years, you should replace any sections of parking lot that have succumbed.
When you apply a sealcoat, you should coat your entire parking lot whether there are signs of cracking in all areas of the asphalt or not. You may, however, be able to save a little bit of money on replacing damaged asphalt by starting with the most damaged sections of the parking lot and then replacing other areas as the need arises. While you may be able to patch a few cracks on your own, in order to make sure that jobs such as sealcoating and repaving are done right, you should leave them to the professionals.

After saving money for years, I was finally ready to build my dream home with a team of professional contractors.

It was really incredible to see the things that I wanted come to life, and within a few months, my home was underway. I can honestly say that I was incredibly pleased with our construction team, and I couldn't have done it without them.
