It is entirely possible to apply asphalt pavement over a concrete parking lot, street or driveway. In addition, potholes and other significant damages to the concrete should be repaired prior to applying asphalt. With time, cracks may form in the asphalt above the expansion joints.
However, if your concrete is relatively sound and raising its elevation a few inches would not create problems, then you can pour new concrete directly over the old. If you bond new concrete to old, any cracks in the existing slab will transfer up into the new slab, and usually within a day or two.
Nearly any size crack can be patched with concrete or cold-patch asphalt, depending on your driveway type, or with some very effective specialty materials. Or, you can simply mix concrete and apply it with a trowel. To fix large holes and deep cracks, fill them with gravel to within 4 in.
Do it Yourself Asphalt Driveway. Making your own asphalt driveway is hard work, and not a job for one person. If you have friends who will help you, it is possible to save a lot of money by doing your own driveway, even after the cost of rental equipment is factored in.
Asphalt takes six to twelve months to fully cure, and remains a little more susceptible to damage for that time. However, it takes 48 to 72 hours to "dry" enough for foot and vehicle traffic. This is for new asphalt. Resurfaced asphalt can be dry in as soon as a few hours.
Cost. Ignoring any maintenance costs, asphalt is generally much cheaper to install than concrete. On average, the cost per square foot for asphalt will run between $2.50 to $4.00. It's not unheard of to have a stained concrete driveway with a smooth finish cost over $15.00 per square foot.

Avoid using an excavator on smaller slabs of asphalt that can be ripped up by hand. If you're tearing up a small section, use the jackhammer to break up the asphalt and then further chip away at it with the pick-axe.
Potholes are holes in the roadway that vary in size and shape. They are caused by the expansion and contraction of ground water after the water has entered into the ground under the pavement. When water freezes, it expands. Water will freeze at 32 degrees Fahrenheit.
