Paving a driveway is a great idea because it cuts down on the amount of dust and debris that enters your garage, but it also cuts down the amount of wear and tear on your vehicle. There are really only two long-term options for paving a driveway. You can either choose to pave with asphalt or with concrete. Both of these materials is used a great deal, but there are independent benefits from each. While both may be a great option, you want to choose the option that is best for you. Here are a couple reasons that you should choose to pave with asphalt.
Asphalt is engineered to be extremely durable, and there is a lot of engineering and research that goes into asphalt. Mixing limestone aggregate and bitumen, which is a type of hydrocarbon, creates the material. These two materials are mixed into a extremely viscous fluid and then steamrolled to create your asphalt slab. One of the most important aspects of the asphalt is the type of limestone aggregate that is chosen to be the base of the asphalt. The limestone needs to be extremely dense with little to no micro pores. The more micro pores in the limestone the more likely water is to enter the micro pore, freeze, and then expand and break down the limestone. If you get a high quality limestone your limestone slab will last a very long time.
A major problem with other types of pavement is a freeze and thaw cycle. When materials freeze or become cold they will shrink. When materials heat up they will expand. If the material is subject to multiple freeze and thaw cycles then it is likely to break down. However, the elastic nature of the asphalt makes this type of material extremely resistant to breaking down due to freeze and thaw cycles.
If you are still on the fence as to whether asphalt is a good paving material, consider that asphalt is relatively easy to refinish. In many instances small cracks can be patched up with either a patch mix from your local home improvement store, or they can be sealed with a polymer fluid. In instances where the cracks have become serious, you can simply resurface the asphalt slab. This usually includes a paving contractor using the original asphalt slab as a base, and pouring a thin layer of asphalt on top.
