Stress-Relieving Interlayers for Bituminous Resurfacings
The study reported was initiated to determine the effectiveness of stress-relieving interlayers (SRIs) in reducing reflective cracking in bituminous overlays on flexible pavements. SRI test sections were installed in 1980 and 1981 at five locations comprised of both 1- and 2-1/2-in. overlays. Before construction, cracks were mapped in detail and deflection was measured to determine causes of cracking. SRIs tested included full-width nonwoven and woven fabrics, rubberized-asphalt surface treatments, reinforced rubberized-asphalt strips, and composite fiberglass-asphalt binder systems. Construction of these test installations is summarized. Results of annual surveys have yet to prove conclusively the value of using these materials or their comparative effectiveness.
