Pros: 1  Economical option. Homeowners appreciate the sleek appearance of an asphalt-paved driveway at a lower cost than concrete or paver surfaces. 2  Flexible in extreme climate conditions.

Q. How can I prevent scaring on my new driveway? Cars starting out too fast, pulling in too quickly, and just plain driving too fast can scar blacktop. During the first 6-12 months while the blacktop is curing, don't park in the same spot every time. Do not turn your steering wheel back and forth when your car is not moving. Avoid using jack stands or car ramps unless a piece of plywood is placed under them to help distribute the weight. Q. My neighbor got a new driveway about two months ago. I can already see tire marks where they park.
