Your new asphalt pavement will look attractive in your yard and create a smooth surface as soon as it is installed. Overtime, the true stability within your asphalt's installed foundation base will become evident in how well it holds up under its existing environmental conditions. Depending on the climate you live in, for example, the weather may bring freezing temperatures and wet weather during winter that can cause the moisture to permeate the asphalt to freeze and expand. Here are some tips to help you make sure you asphalt's base is installed appropriately.
Prepare the Site
An important part of installing a new pavement surface is preparing its base, or foundation, to help your asphalt's surface be more able to withstand weather, traffic, and temperature fluctuations. A solid gravel base for your new pavement essentially gives your asphalt its flexibility and stability to help it last as long as possible.
First, excavate off the layer of topsoil from the area, which you can use to build-up soil and landscaping in other areas of your yard. Removing the topsoil also provides space for installation of your asphalt's gravel foundation.
You can rent a mini excavator or track loader from a local tool rental business to remove the soil and level the area. For a small area, you can complete the topsoil excavation with a shovel and rake.
Check the Base Soil
To help prepare your asphalt against wet and freezing weather, it is necessary to create proper drainage beneath the paving. Check the type of soil that exists in the prepared ground where you have excavated any topsoil for the job.
Take a fist-full of soil and squeeze it in your hand. When you release the soil and it stays clumped together, your soil is a poorly-draining soil. If the soil falls apart when you release it in your hand, it has a more sandy consistency and has better drainage properties.
Install a Drainage Layer
After you determine the type of soil in the ground where you will install your asphalt, you can add the appropriate drainage layer of gravel. This gravel will help water flow beneath the asphalt and prevent moisture from building up and causing damage to the asphalt layer above it.
For poorly-draining soil, it is recommended to install a layer of crushed gravel that is eight inches thick. For soil that contains more sand, you will only need to pour a crushed gravel layer four inches thick. Be sure to compact the gravel with a compactor machine or roller to compress the angular gravel pieces together and create a more stable surface for the asphalt.
