Though they may look similar, tar and bitumen come from different sources. Bitumen is a petroleum product—extracted during crude oil refining—and is mostly made up of hydrocarbons. Tar comes from burning down organic materials like coal or wood. Bitumen is strictly oil-based, while tar is a mix of compounds from natural sources. Both are used as binders in paving; however, bitumen is the standard for today’s asphalt. Tar use has mostly faded out of road construction.

Asphalt dries and cures best between 50 and 85 degrees Fahrenheit. This range allows moisture to evaporate quickly without causing the asphalt to cool too fast, which can negatively affect the drying process. However, keep in mind that other weather conditions can also affect curing and drying times, such as precipitation and humidity.

Driveway sealcoating costs around $500 on average, or between $1.25 and $1.50 per square foot for materials and labor. Most homeowners pay between $250 and $800 for this service. Your project price will depend mostly on the size of your driveway, the type of sealant, how much pressure washing or treatment is required before sealing, and the number of coats of sealant applied to your driveway. Most sealants come in 5-gallon or 55-gallon units, with up to 500 square feet of coverage per 4 gallons.

Maintaining a driveway depends on the material your driveway is made of. Concrete and asphalt should be sealed to protect against water and freeze-thaw cycles. Cracks and expansion joints should be filled with a flexible polyurethane caulk or asphalt sealer. Before you apply a sealant to your driveway, consider pressure washing the surface. It will take off any loose sealant and any grime that might have caused a stain. Sealing over dirt and stains will trap it under the sealer.

If you live in colder climates, consider using sand rather than salt to de-ice. Sand helps melt the snow and ice without speeding up the freezing and unthawing process of your driveway, which helps prevent cracks from forming from the constant fluctuation of temperatures.
