An asphalt driveway is one that can stand the test of time without crumbling or falling to pieces. Although a brick driveway is pleasing to the eye, it will fade, crumble and break over time, creating an eyesore that is expensive to patch and maintain. An asphalt driveway, on the other hand, is sturdy and rather simple to maintain and keep clean. However, installing asphalt over a brick driveway is tricky. You could remove the old driveway, but that can take a lot of time, create a huge mess, and cost much more money. The information in this article will show you how to install an asphalt driveway on top of a brick driveway.
Step 1 – Clean the Brick
Your brick driveway can become very dirty and oily during normal use. This grime can cause the asphalt to not adhere properly. This can then turn your new asphalt driveway in to a giant mess come the first snow storm of the year or heat wave. To keep this from being an issue, use a push broom to remove all of the debris from the brick driveway. Go over the driveway several times to make sure the dirt is gone. Use a power washer and plain water to further clean the brick driveway. This will also help to remove any loose brick or mortar. Allow the brick to dry overnight.
Step 2 – Mixing the Asphalt
The asphalt has to be hot in order to be used, as the crude oil used to bind the gravel will harden and be difficult to work worth. Make sure the asphalt is steaming and around 300-degrees Fahrenheit. Use the rake to continuously mix the hot asphalt in the wheelbarrow. This will keep the mixture from setting too quickly. Make sure this is maintained throughout the next step or else the asphalt will harden and be impossible to work with.
Step 3 – Applying the Asphalt
Work in sections, or the asphalt could harden. With a shovel, apply the hot asphalt directly on top of the brick. It will begin to cool immediately, so you will have to work quickly. Spread the asphalt over the brick using the hoe. Make sure you fill all of the cracks and holes of the brick in the mortar lines. Once the asphalt is spread out, use the tamper to flatten it out to approximately 1-inch thick. Shovel another mound of asphalt on the brick driveway, slightly overlapping the previous section. Spread it out and tamp it down. Overlapping the sections allows them to adhere together while they cool down. Use the hoe to even out the edges as well for each section. Continue in this fashion until the brick driveway is transformed into an asphalt driveway. It is also good to note that you should never attempt this task when rain is possible. You need at least two days of good weather before sealing the asphalt driveway.
