Hot mix asphalt (HMA) pavement may be cheaper as a first cost, but what about life cycle cost?

Properly designed and constructed HMA pavements are the most economical to maintain over the long term. A comparison study of Ohio’s Interstates has shown that original HMA pavements have been cheaper to maintain throughout their lives than concrete pavements and have never had to be reconstructed or replaced. Another reason 93% of roadway surfaces are asphalt. For more information on the comparative costs of maintaining pavements, see our study Economic Evaluation of Ohio’s Flexible and Rigid Interstate Pavements.
