Abstract:
This report discusses preliminary evaluations of adhesive use along longitudinal paving

joints on hot mix asphalt pavements to help prevent longitudinal cracking. Seven

pavements where adhesive was applied to the vertical or sloped face of the first lane

paved prior to overlaying the second lane are being evaluated for development of

centerline cracking and ravelling. Three pavements were overlaid in 2004 and four

pavements were overlaid in 2005. Three adhesive products made by different companies

were used at bead widths of 2 inches and 4 inches. The 2 inch bead was used on all

pavements while the 4 inch bead was used on two pavements. All but one pavement had

non-adhesive (control) section. This report only evaluated the use of longitudinal joint

adhesives on overlays, although the adhesive could be used on the top layer of newly

reconstructed pavements. This is a review of the distress found after at least one followup

visit to all sites. A summary of the literature search is also presented.

Conclusions from the limited data available were that longitudinal joint adhesives

sections appear to be performing as least as well or better than non-adhesive sections.

Further, using adhesives along centerline paving joints appears to be practical partial

solution to longitudinal joint cracking. Additional site evaluation is required to determine

long-term performance and cost effectiveness of the longitudinal joint adhesives.
