Rubber Asphalt Binder 'Stress Absorbing Membrane Interlayer'

摘要

Experimental installation of rubber-asphalt binder stress absorbing membrane interlayers were evaluated for their ability to delay or prevent reflective alligator cracking. The final results are inconclusive in that after 10 years of service life neither the control sections paved without an interlayer or the remainder of the projects paved with the interlayer have shown any reflective alligator cracking. It is suspected that the thickness of the overlay in combination with the sound structure of the underlying pavement has masked any of the benefits of the interlayer.
