We do not want to pave over concrete. It is not the inexpensive solution you may be seeking. Concrete has expansion joints and moves with changes in temperature (primarily during freezing and thawing). Asphalt is paved as a single monolithic slab. Unlike concrete, it has some inherent flexibility that allows it to expand and contract; however, it is not designed to move in the same way that concrete does. Consequently, asphalt applied over concrete will crack whenever and wherever the concrete moves. This includes both expansion joints and other cracks that the concrete has developed with age. Any expansion joint or a crack in the concrete pavement below it will soon be expressed in the asphalt above. This defeats the purpose of paving. In addition, this process creates a trip hazard in some areas. Finally, because there is no way to tuck asphalt, overlaying concrete can also produce a thin edge susceptible to accelerated deterioration. In short paving with asphalt over concrete is a very bad idea.
