Rubberized Asphalt Pilot Road Trial in Kuwait
Results of an investigation carried out at the Kuwait Institute for Scientific Research (KISR) are presented showing the advantages of incorporating PelletPave (a rubber-bitumen additive in pelletized form) as partial substitute to conventional bitumen in rubberized hot mix asphalt (rubberized-HMA). The Pelletpave was composed of 18% tire derived crumb rubber blended with 60/70pen grade bitumen and processed by USA technology provider Phoenix Industries LLC into easy to handle granular/pellet form. Laboratory mix designs were followed up with full scale asphalt plant trials and the construction of a pilot trial (mill and replace an old wearing course) to test out the technology. The trial comprised 3 different test sections to compare the performance of rubberized-HMA with polymer modified Marshall asphalt and polymer modified SuperPave asphalt mix formulations. The test sections were laid on a low-medium trafficked road and one year following the trial, the performance of the rubberized-HMA appears to be on par with Polymer Modified HMAs.
