When you are planning to put in a driveway, you really only have a few choices. You can install a concrete, asphalt, or gravel driveway. Gravel is a good temporary solution, but over time the gravel can become a hassle. Concrete and asphalt are the two best choices that you will have, and each of the options have pro's and con's. This article is going to focus on asphalt and why it is one of the most commonly used materials for paving driveways, parking lots, and even highways. Here are three reasons that you should seriously consider using asphalt for your paving project.
Asphalt is made from limestone aggregate and bitumen. One of the most important aspects of the asphalt is the limestone aggregate that accounts for the majority of the material. Engineers and geologists have long worked on making a better asphalt, and have come a very long way. The limestone that is utilized in many of the asphalts now is a very low porosity and permeability, connectivity of tiny holes, limestone. The reason that this is significant is water, and the freeze cycle. If water is able to penetrate the porosity and permeability of the rock and then freeze the aggregate starts to erode away. So, the more dense limestone aggregate being used for the asphalt has significantly helped roads last longer.
When laying concrete, if the foundation is not completely flat, you could end up with a broken slap within just a few months. However, the aggregate and bitumen that makes up asphalt is flexible, and can actually bend and fill small dips in the foundation. The flexibility of the material is very useful when considering freezing and thawing cycles. The material is able to expand and contract without any major problems.
Asphalt is known for lasting a very long time. One of the best ways to prolong the life of your asphalt is to seal it. Over time however, there will come a time when the asphalt starts to crack and break. This is when you can go to your home improvement store and buy high quality asphalt sealant. Once again you will be able to put the sealant in any crack and prolong the life of your pavement. When it is time to replace the asphalt, 20-30 years down the road, you will be able to use the asphalt you have on your property now as a solid base.

About a year ago, I realized that there were all kinds of problems with our home's pavement. The driveway seemed to be chipping apart and the front walkway was desperately cracked. I knew that I had to do something to improve things, so I started working on getting bids to improve things. It was amazing to see how many different pavement options we had and how great of a job one contractor eventually did. The difference was astounding after all of the pavement was broken out and things were fixed. This blog is all about improving your paving and making a significant difference in your home.
