A study of asphaltic pavements ranging in age from 3 to 42 years, taken from several locations in the State of Kansas (USA) revealed that bacteria belonging to the family Pseudomonadaceae and the genus Thiobacillus appear to play an important role in the deterioration of asphaltic materials. The pinhole effect on the stripping of asphalt from aggregate surface is described alongside the synergistic effect of moisture and bacteria on asphalt deterioration.
