| dc.description.abstract | The purpose of this study is to evaluate the performance of rubber modified asphalt mixture incorporating silane additive Zycotherm. The service characteristics of rubber modified asphalt mixture were evaluated using workability index and compaction energy index to indicate the ease of asphalt mixture to be placed, handling and compacted. Besides, the engineering properties of asphalt mixture were evaluated in terms of Indirect Tensile Strength (ITS), Resilient Modulus, permanent deformation, moisture susceptibility resistance and Leutner Shear (LS) Test. The asphalt mixture was prepared and compacted at 4 ± 1 % air voids which according to the Standard of Public Work Department of Malaysia’s (PDW), whereas the moisture susceptibility resistance was tested with using asphalt mixture compacted at 7 ± 1 % air voids. Based on the results, it was found that crumb rubber modified asphalt mixtures have a better performance in terms its tensile properties, permanent deformation, resilient modulus, shear resistance and moisture resistance. From the workability and compaction energy index, unmodified asphalt mixture is better than modified asphalt mixture. The asphalt mixture performance generally favours to the modified asphalt mixture. Therefore, modified asphalt mixture has better performance against the high traffic intensity and axle loads. | en_US |
