At an installed cost of about $7,000, itâs an appliance that makes very little financial sense for most people. Tesla lists the price of the battery at $3,500, but that does not include installation, or an additional piece of equipment called an inverter that is needed to connect the battery to the home.
Strong blacktop driveways are typically built using crushed angular gravel as a base. This gravel needs to be a minimum of 6 inches thick for light vehicle traffic such as cars. If you expect larger commercial trucks on your driveway, I would install a gravel base that is a minimum of 8 inches thick. The soil beneath the gravel must also be of good quality.
For example, let's calculate how much concrete is needed for a 5-inch thick rectangular driveway, 60-feet long (length) and 18-feet wide (width). The area of the driveway is 1,080 square feet (60-feet x 18-feet). According to the table above, one cubic yard of concrete placed at a thickness of 5-inches covers 65 square feet.
