The purpose of this synthesis is: to identify the various materials and techniques used to reseal joints and cracks in rigid pavements and cracks in flexible pavements; to determine the costs associated with the use of these materials and techniques; to determine changes in pavement performance resulting from resealing joints and cracks; and to develop criteria for resealing joints and cracks if this practice is found to be beneficial. The scope of this report is limited to the sealing of individual cracks and joints; such area-wide crack sealing techniques as surface treatments, slurry seals, or squeegee-type applications are not described. However, it should be noted that slurry- seal material is used, in some cases, to seal individual cracks and as such is discussed in this synthesis. (Author/publisher)
