EFFECT OF MOISTURE IN BITUMINOUS MIXTURES AS EXPERIENCED IN FIELD PAVEMENT OPERATIONS IN MICHIGAN

Stripping of asphalt from the aggregate, in the presence of water, has been observed by many people. This may be caused by incompatability of certain asphalts with different aggregates in the presence of moisture. Most asphalt technicians recognize that the presence of asphaltic acids in the asphalt gives better adhesion to non-acid or limestone type aggregates, however in contrast this may cause stripping if used with siliceous aggregates. Numerous studies of these conditions have been made and many anti-stripping additives have been developed. However, the writers' observations indicate that the long range benefits of these additives are still to be proved. With the advent of the elevated grades on most modern highways, it is seldom that we find an asphalt pavement submerged in water for long periods of time. This, I believe, has pretty much solved the stripping problem in Michigan and, more than likely, in most other states. (Author)
