Asphalt-Rubber Binder Stress Absorbing Membrane Interlayer. Wheeler I/C to Adams Co. Line, I-90

摘要

This is the final report of an evaluation of an Asphalt-Rubber Binder Stress Absorbing Membrane Interlayer (SAMI) to control transverse, alligator and longitudinal cracking in the asphalt concrete overlay. A control section consisting of a tack coat of CSS-1 applied to the existing pavement was used to compare against the Asphalt-Rubber SAMI and a paving grade asphalt SAMI. Crack mapping for a period of 9 years disclosed the Asphalt-Rubber SAMI to perform slightly better than the paving grade asphalt and much better than the control.
