How do you install a tar and chip driveway?

A:

Quick Answer

To install a tar and chip driveway, place a layer of gravel in the desired area to form the base of the driveway, and pour a layer of liquid asphalt over the gravel. Place one or two layers of chipped stone on the asphalt, and compact the driveway to embed the stone in the tar. Allow the driveway to cure for at least 24 hours before using it.

Full Answer

If an existing driveway is installed and is in good condition, the tar and chip is installed directly over the driveway. Install the driveway when the temperatures are 70 degrees Fahrenheit or above, and when the ground is dry.

Apply at least 1/2 gallon of asphalt per square foot, and apply the chips to the asphalt within one to two minutes to ensure the stones stick to the asphalt. Do not pour too much asphalt, as this may cause the tar to show through the layers of stone. The stones are coated in a tar-like coating to help them stick to the asphalt, then sprayed onto the asphalt while the asphalt is soft.

Heavy equipment and the assistance of several people are necessary to create a tar and chip driveway, making the project most suitable for a professional team. Experience working with hot tar promotes safety and ensures the driveway is properly installed.
