How to Build an Asphalt Driveway

You must have specialized training and equipment for the installation of a new asphalt driveway. A lack of access to said equipment and training often puts the job out of reach for DIY lovers, but it can still be helpful to know all of the process steps. You can better read an estimate and keep an eye on progress when you have a detailed understanding of the steps involved. Here is how to build a new asphalt driveway:

Demo

Regardless of the material of your old driveway, you have to demolish it before you can add in a new asphalt driveway. Existing driveway demolition will require dump trucks, forklifts, and other heavy machinery. Once the driveway has been removed, the existing pieces are hauled away to be recycled.

Making the grade

Water intrusion is the most significant cause of damage to asphalt driveways. The introduction of water to existing asphalt can cause heaving, cracking, and even potholes. Therefore, contractors will grade the soil as needed to guarantee proper runoff and protect it from damages caused by water.

Bring in the sub

The next step in creating a new driveway involves adding a long-lasting and durable sub-base. Sub-bases range from 4 to 8 inches in thickness and are composed of aggregate. The solid, stable support of the sub-base acts as a frost barrier for new asphalt. Depending on your driveway needs, the aggregate added may be of various types, and the sub-base could range between a variety of thicknesses.

Binding

A binding agent made of oil and large aggregate is then laid on top of the completed sub-base. The binder adds durability and strength to a finished asphalt driveway.

Pour It Up

With the sub-base complete, it's time to pour and compact the new asphalt. This part of the job is surprisingly fast. The high temperature of hot mix asphalt makes it vital to smooth and compact it before its flexibility and warmth have dissipated. This sand, oil, and small aggregate mixture will eventually settle into a shiny, hard, smooth surface.

Not Yet!

Your new driveway will not be ready for use immediately. Experts recommend not parking large, heavy equipment for 30 days and waiting 72 hours before parking or driving passenger vehicles on the newly laid surface. You really shouldn't even walk on it for at least 24 hours. Complete curing of new asphalt paving in Fairfield, CA, can take up to a year, so it is vital to avoid oil or gas spills and keep a piece of cardboard handy to put under motorcycle or bicycle kickstands. Repeating the process every two to three years will assist in protecting it from future water damage.

Resealing will extend its life and keep your new asphalt driveway looking its very best.
