Can you Pave over Concrete?

Can you Pave over Concrete? asphalt paving austin txIt is entirely possible to apply asphalt pavement over a concrete parking lot, street or driveway. In fact, many state and government agencies routinely apply an asphalt overlay on top of a concrete roadway across the country and in Austin, Texas!

Because asphalt derives its strength and durability from a solid foundation, concrete is ideally suited for an asphalt overlay. However, like any other foundation used for asphalt pavement, the concrete needs to be in good condition before the asphalt is applied.

Concrete is typically poured in individual blocks with expansion joints between each block. If the soil beneath the concrete shifts, blocks can be lifted up or move apart. It is not advisable to apply asphalt over a concrete surface that has large gaps between the blocks or that is uneven due to movement. 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. This is normal and is no cause for alarm. However, it is important to have these cracks filled as soon as possible as they can allow water to become trapped beneath the asphalt. This can damage the asphalt surface, especially in areas where the ground freezes in the winter, and cause extensive cracking of the asphalt.

An asphalt overlay can look attractive and function superbly for many years. Like concrete, asphalt needs to be properly maintained to reach its full life expectancy. Properly installed concrete that is in adequate condition is one of the best foundations for asphalt pavement.
