| Resumo: | This study presents the results of the research to investigate asphalt rubber mixtures produced with asphalt rubber binder obtained from two different processes; (i) terminal blend (produced in refinery); (ii) continuous blend (produced in laboratory). The experiment included the evaluation of fatigue and permanent deformation resistance of two gap graded mixtures (Caltrans ARHM -GG; ADOT AR-A C) and a dense gradation Asphalt Institute (AI) mix type IV) Two asphalt rubbers from terminal blend process were used with 15% and 20% of crumb rubber content. The asphalt rubber from continuous blend process was obtained with 21% of crumb rubber. Each gradation was used to produce mixtures using asphalt rubber from both processes (continuous and terminal blend). The results showed that asphalt-rubber mixtures with terminal blend process presented best performance for rutting and the mixtures from continuous blend presented better fatigue life. |
