Sealing cracks in flexible pavements interim report III - laboratory tests of asphalt sealants

Abstract

A survey of literature pertaining to materials and methods of sealing highway pavement cracks indicated a scarcity of information and a lack of standard testing procedures for asphalt pavement crack sealants. Therefore, the proposal for research on "Sealing Cracks in Flexible Pavements" called for evaluating and/or developing a series of laboratory test procedures that could be used to predict a sealant material's ultimate field performance.
