The first thing that I want to address is that I am not going to reference any web pages, recite random statistics, or any science that may be hard to follow. That being said let's get started. All the benefits that I am about to state come from first hand experience.
The number one benefit that comes to mind is a simple one to understand and quite possibly the most important. The first thing you notice after a driveway has been freshly sealed is its rich black color. There is more to it than just looks. The dark black color attracts the sun and in return yields higher surface temperatures which helps the asphalt stay flexible (think elderly in Florida). Why is this important you ask? I will explain... When you pull onto your driveway you are putting loads north of 2,000lbs with the average vehicle onto the surface. The driveway will flex underneath you to accept the weight of the car. Much like standing on the middle of a board supported by a bucket on either end; unsealed driveways become very brittle, ridged, and lose all flexibility. So when you pull your car on your driveway it is no longer able to accept the load and starts to crack under the pressure. Think of a sealed driveway as a water bed; the way it accepts your weight and adjusts time and time again. Now think of an unsealed driveway as the stiffest mattress you have ever slept on. Also that same black color will aide you in removing snow and ice off of your driveway a lot faster than an unsealed driveway. There are other factors that come into play here like sealer's ability to waterproof your asphalts surface; which in result sheds water faster and easier( I will address this later on). This is all I have in me for tonight, but let's go over the key items here (there will be more benefits to come).
-Rich black color attracts sun (higher surface temperatures melts snow/ice)
-Higher surface temperatures equals a more resilient driveway under load
-Flexible driveways have a greater resistance to cracking
-It does beautify your property (hate the term beautify, not sure who started it)
-A new canvas for your kids to draw on
