A broad spectrum of materials which may have potential for improving the characteristics of pavements with regard to ruducing future maintenance were reviewed with those materials or materials systems possessing the most advantages being considered as candidates for a zero maintenance paving system. These included Gussasphalt, asbestos asphalts, sulfur modified asphalts, noncalcareous inorganic cements (sulfur and phosphate), expansive cements, fiber reinforced concree, polymers in concretes, sealants, ceramics, prestressed concrete and vacuum processed concrete. These materials were compared to conventional asphalt and portland cement concrete systems on the basis of mechanical properties, ease of construction and maintenance, environmental compatibility, availability, cost, and possible uses. None of the materials or materials systems studied will provide a singular answer to the problem of zero maintenance. However, many of the materials possess characteristics which could be incorporated into pavements to greatly extend the period prior to maintenance. /Author/
