Keywords	asphalt-rubber, SAM, SAMI, cracking
Description	An asphalt rubber membrane was used as a stress absorbing membrane (SAM) and as a stress absorbing membrane interlayer (SAMI) over a jointed concrete pavement. This project is located on Interstate 30 in Little Rock. Approximately 5 years after the asphalt rubber membrane was placed, the project was surveyed with the following results: 1. The control section showed 25% of the joints has reflected through; 2. The SAM section averaged 25% joint reflection,and 3. The SAMI section averaged 20% joint reflection. The results indicate that the use of a SAM and/or SAMI was not effective in retarding joint reflection cracking.
