STATE MAKES CLOSE CALL ON CONCRETE VS ASPHALT

After several months of research, the Delaware Department of Transportation has opted to use concrete as opposed to hot-mix ashphalt on the main lanes of its $500 million, 41-mile U.S. Relief Route project. Life cycle cost analyses indicate that a rigid pavement would cost 2 to 12% less over 20 to 50 years. Concrete got the edge on the project because large trucks with high tire pressures will use the route and most of it will be built along new alignment. However, hot mix will be used for the 8-ft right shoulders, the 4-ft left shoulder and on most of the intersecting roads along the route.
