Nebraska Experimental Asphaltic Concrete Resurfacing Project F-171(12). Part IV
An asphaltic concrete overlay, consisting of 18 experimental sections, was constructed in 1961 to study the performance of several types of mixtures. Periodic inspections were made to determine cracking, rutting and wear, and cores were taken to monitor pavement density changes. No pavement failures caused by instability were observed in any section. Rutting was generally light, and there was no pavement bleeding. Several sections developed moderate to severe cracking, raveling and wear. In 1969 ten sections were overlaid with Type C asphaltic concrete. The remaining eight sections were in fair to very good condition in May, 1972. Voids in mineral aggregate filled with asphalt, calculated on the basis of final pavement density, showed very good correlation with the durability of the material. The performance of Nebraska Type A, Type C and Bridge Mix asphaltic concrete was good. (Author)
