This is a very popular process in Arizona. Advantages of a Chip Seal are:

–  Lighter driveway color

–  Cooler temperature output

–  More cost efficient than paving

This process begins with first cleaning off the existing surface and in some cases re-grading and re-compacting a dirt surface. After the cleaning and prep work is complete, a layer of CRS-2 oil is sprayed on the surface. Immediately after a layer of 3/8th inch grey rocks are spread and manicured by hand on the hot oil. Final step involves rolling the rocks into the hot oil. On dirt this process is repeated and on existing asphalt it is generally only done once but in certain circumstances a second layer is applied.
