Cracking and Performance of Asphaltic Wearing Surfaces of Certain Highway Sections
A study of three South Carolina highway sections, was conducted to determine the cause of poor performance. Comparison of test results from sites of excellent and poor performance revealed no important differences or defects in the asphaltic concrete pavement and the macadam or sand-clay base. Benkelman beam deflection measurements indicated that the US 378 section, located in the Middle Coastal Plain, had become more uniformly stable with the passing of time, and it was concluded that the early poor performance was probably due to high moisture content of the fills during construction. However, for the two highway sections located in the Piedmont, very high deflections were noted at most sites of poor performance, and it was concluded that the high deflections and severe 'alligator' cracking noted at these sites was due to the presence of elastic, micaceous subgrade soil.
